技术领域Technical field

本公开实施例涉及网络安全技术领域，尤其涉及一种信息共享方法、装置、***、电子设备以及计算机可读存储介质。The embodiments of the present disclosure relate to the field of network security technologies, and in particular, to an information sharing method, device, system, electronic device, and computer-readable storage medium.

背景技术Background technique

随着计算机和网络技术的快速发展，各种网络安全事件频繁发生，新漏洞层出不穷，催生出大量新的安全风险，对网络安全和业务安全造成严重威胁。With the rapid development of computer and network technology, various network security incidents occur frequently, and new vulnerabilities are emerging one after another, spawning a large number of new security risks, posing serious threats to network security and business security.

传统的网络安全模式中，各个安全子***相互独立，安全防护各自为营，使得各项威胁情报信息相对孤立，造成孤岛效应；从而导致各个安全子***无法及时有效地获取或者分析出最新且最有价值的威胁情报信息，进而无法及时进行防护及应急响应，导致安全风险及安全攻击。In the traditional network security model, each security subsystem is independent of each other, and security protection works independently, making various threat intelligence information relatively isolated, causing an island effect; thus, each security subsystem cannot obtain or analyze the latest and most updated information in a timely and effective manner. Valuable threat intelligence information prevents timely protection and emergency response, leading to security risks and security attacks.

因此，为了使各个安全子***协同进行高效的防护工作，威胁情报信息共享平台的构建是网络安全建设中一项非常重要的工作。同时，相关技术中的共享机制中，其共享的威胁情报信息存在被篡改的可能性。Therefore, in order to make the various security subsystems work together for efficient protection, the construction of a threat intelligence information sharing platform is a very important task in the construction of network security. At the same time, in the sharing mechanism in related technologies, the threat intelligence information shared may be tampered with.

具体实施方式detailed description

背景技术中，相关技术中的共享机制中，其共享的威胁情报信息存在被篡改的可能性。In the background art, in the sharing mechanism in the related art, the threat intelligence information shared may be tampered with.

比如，相关技术中，根据预设周期对内网中的未知数据表进行轮询，获得未知数据表中的未知数据；根据未知数据向情报云服务器发送查询请求，并接收情报云服务器返回的包括威胁情报信息的查询结果；将查询结果推送至内网的威胁情报平台，以使威胁情报平台将所述查询结果进行存储，实现威胁情报信息的共享。For example, in the related technology, the unknown data table in the intranet is polled according to a preset period to obtain the unknown data in the unknown data table; the query request is sent to the intelligence cloud server based on the unknown data, and the information returned by the intelligence cloud server is received. The query result of threat intelligence information; the query result is pushed to the threat intelligence platform of the intranet, so that the threat intelligence platform can store the query result to realize the sharing of threat intelligence information.

基于此，本公开实施例提出基于区块链对威胁情报信息进行共享的方案。Based on this, the embodiments of the present disclosure propose a scheme for sharing threat intelligence information based on the blockchain.

下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获取的所有其他实施例，都属于本公开保护的范围。The technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present disclosure.

The electronic device may be an information sharing server for sharing the threat intelligence information provided by the first blockchain node based on the blockchain.

参见图1，图中示出了本公开实施例提供的信息共享方法的流程示意图之一。如图1所示，该方法可以包括如下步骤：Refer to FIG. 1, which shows one of the schematic flowcharts of the information sharing method provided by an embodiment of the present disclosure. As shown in Figure 1, the method may include the following steps:

For example, Node 1 can interact with n-1 nodes such as Node 2, Node 3, Node n-1, Node n; Node 2 can interact with n-1 nodes such as Node 1, Node 3, Node n-1, Node n, etc. Nodes interact; Node 3 can interact with n-1 nodes such as Node 1, Node 2, Node n-1, Node n; Node n-1 can interact with Node 1, Node 2, Node 3, Node n, etc. n- One node interacts; Node n can interact with n-1 nodes such as Node 1, Node 2, Node 3, Node n-1.

应当说明的是，图2中虽示出了5个区块链节点，但是，在图中区块链节点的个数只作为一种示意，并不作为对区块链节点具体个数的限制。在实际应用中，区块链节点的个数可能远不止5个。It should be noted that although 5 blockchain nodes are shown in Figure 2, the number of blockchain nodes in the figure is only used as an indication, not as a restriction on the specific number of blockchain nodes . In practical applications, the number of blockchain nodes may be far more than 5.

本公开实施例中，区块链节点从功能上划分，可以存在多种类型，每种类型的区块链节点可以包括多个，所述第一区块链节点为提供威胁情报信息的区块链节点，可以称之为威胁情报提供者，也可以称之为威胁情报源，所述第一区块链节点可以是专业威胁情报厂家、防病毒厂家、防APT厂家、检测类产品厂家、免费情报联盟、客户等角色。In the embodiments of the present disclosure, the blockchain nodes are functionally divided, and there may be multiple types, each type of blockchain node may include multiple, and the first blockchain node is a block that provides threat intelligence information.

这里，本公开实施例中电子设备在接收到威胁情报信息之后，基于第一共识算法，对威胁情报信息进行共识，共识之后，对威胁情报信息进行记录，可以记录获取到威胁情报信息的时间，以在区块链中实现对区块的同步。Here, in the embodiments of the present disclosure, after receiving the threat intelligence information, the electronic device agrees on the threat intelligence information based on the first consensus algorithm. After the consensus, the threat intelligence information is recorded, and the time when the threat intelligence information is acquired can be recorded. In order to realize the synchronization of blocks in the blockchain.

记录威胁情报信息之后，即可进行区块链中共享区块的构建。参见图3，图中示出了本公开实施例提供的信息共享方法中共享区块的结构示意图。After the threat intelligence information is recorded, the shared block in the blockchain can be constructed. Refer to FIG. 3, which shows a schematic structural diagram of a sharing block in an information sharing method provided by an embodiment of the present disclosure.

如图3所示，共享区块包括区块头和区块体。其中，区块头由前一共享区块的散列值、Merkle根、随机数、时间戳构成。区块体可以包括威胁网络安全的IP地址信息、威胁网络安全的域名信息、威胁网络安全的URL信息、威胁网络安全的安全事件信息、威胁网络安全的漏洞信息中的至少一种。As shown in Figure 3, the shared block includes a block header and a block body.

The block body may include at least one of IP address information threatening network security, domain name information threatening network security, URL information threatening network security, security event information threatening network security, and vulnerability information threatening network security.

同时，为了解决威胁情报源众多，无法有效判定威胁情报源是否可信，以及贡献率高低的问题，区块体中还可以包括对威胁情报源的评级参数，所述评级参数可以基于第二区块链节点针对威胁情报源共享的威胁情报信息的调用而更新，其具体更新过程将在以下实施例中详细说明。At the same time, in order to solve the problem that there are many threat intelligence sources, it is impossible to effectively determine whether the threat intelligence source is credible, and the contribution rate is high or low, the block body can also include the rating parameters of the threat intelligence source, and the rating parameters can be based on the second zone. The block chain node is updated in response to the invocation of the threat intelligence information shared by the threat intelligence source, and the specific update process will be described in detail in the following embodiments.

具体地，前一共享区块的散列值，是由前一个共享区块的所有信息加上前时间戳，通过哈希所产生的值。Specifically, the hash value of the previous shared block is the value generated by hashing from all the information of the previous shared block plus the previous timestamp.

Merkle根，是由区块体中所有信息构成Merkle树，计算Merkle树根的散列值，该值可以将区块头和区块体绑定起来。The Merkle root is a Merkle tree composed of all the information in the block body, and the hash value of the Merkle tree root is calculated. This value can bind the block header and the block body.

随机数，是当前节点根据所有的公钥信息以及当前时间戳，通过SHA256哈希算法来产生一个随机数，此随机数要求下一个共享区块的哈希值要以该数目为开头的一串数字，通过该随机数可以防止攻击者伪造区块链的区块。A random number is a random number generated by the current node through the SHA256 hash algorithm based on all public key information and the current timestamp. This random number requires the hash value of the next shared block to start with this number. Number, through which the random number can prevent the attacker from forging the block of the blockchain.

时间戳，是发布该共享区块的节点在发布时打的时间标记，从1970年1月1日00:00 UTC开始，到该共享区块产生时间隔的秒数。The timestamp is the time stamp stamped by the node that released the shared block at the time of release, starting at 00:00 UTC on January 1, 1970, and the number of seconds between when the shared block was generated.

对威胁情报源的评级参数包括威胁情报源可信度、威胁情报源贡献率和威胁情报源的级别。威胁情报源可信度，是威胁情报源的可信度相关信息，威胁情报源贡献率，是威胁情报源的贡献率相关信息，威胁情报源的级别是威胁情报源的等级相关信息。The rating parameters of threat intelligence sources include the credibility of threat intelligence sources, the contribution rate of threat intelligence sources, and the level of threat intelligence sources. Threat intelligence source credibility refers to the credibility-related information of the threat intelligence source, the contribution rate of threat intelligence source is the contribution rate related information of the threat intelligence source, and the level of the threat intelligence source is the level-related information of the threat intelligence source.

基于所述威胁情报信息，按照共享区块构建的结构特性，生成第一共享区块。Based on the threat intelligence information, the first shared block is generated according to the structural characteristics of the shared block construction.

同时，基于构建的各个共享区块，即可构建一条区块链链路，参见图4，图中示出了区块链的链式示意图。如图4所示，该区块链由创世区块、共享区块1、共享区块2···共享区块m-1、共享区块m组成。At the same time, based on each shared block constructed, a blockchain link can be constructed, as shown in Figure 4, which shows a chain diagram of the blockchain. As shown in Figure 4, the blockchain is composed of a creation block, a shared block 1, a shared block 2, and a shared block m-1, and a shared block m.

应当说明的是，第一共享区块为基于威胁情报源提供的威胁情报信息构建的初始区块，因此，对威胁情报源的评级参数可以默认为0。It should be noted that the first shared block is the initial block constructed based on the threat intelligence information provided by the threat intelligence source. Therefore, the rating parameter for the threat intelligence source can be 0 by default.

步骤103，在所述第一共享区块被接收所述第一共享区块的多个区块链节点共识的情况下，将所述第一共享区块写入至区块链中。Step 103: In the case where the first shared block is received by the consensus of multiple blockchain nodes of the first shared block, write the first shared block into the blockchain.

电子设备生成第一共享区块之后，会广播该第一共享区块。具体的，将第一共享区块发送给与第一区块链节点同类型的所有区块链节点，这些区块链节点接收到第一共享区块后，会对第一共享区块进行共识，共识通过之后，将结果发送给该电子设备。After the electronic device generates the first shared block, it will broadcast the first shared block. Specifically, the first shared block is sent to all blockchain nodes of the same type as the first blockchain node. After these blockchain nodes receive the first shared block, they will reach a consensus on the first shared block. After the consensus is passed, the result is sent to the electronic device.

在所述第一共享区块被多个区块链节点共识通过的情况下，将所述第一共享区块写入至区块链中。In the case where the first shared block is approved by a consensus of multiple blockchain nodes, the first shared block is written into the blockchain.

应当说明的是，将所述第一共享区块写入至区块链中的前提条件，即第一共享区块被区块链节点共识通过的个数可以根据具体情况进行设置，可以设置成相对所有区块链节点个数的预设百分比，如50％，也可以设置成预设数值，如6个。总之，只要所述第一共享区块被预设个数的区块链节点共识通过后，电子设备即会将所述第一共享区块写入至区块链中。It should be noted that the prerequisite for writing the first shared block to the blockchain, that is, the number of the first shared block passed by the consensus of the blockchain nodes can be set according to the specific situation, and can be set to The preset percentage relative to the number of all blockchain nodes, such as 50%, can also be set to a preset value, such as 6. In short, as long as the first shared block is approved by the consensus of a preset number of blockchain nodes, the electronic device will write the first shared block into the blockchain.

上面详细介绍了基于威胁情报源提供的威胁情报信息，对共享平台的构建，下面将详细介绍基于共享平台是如何对威胁情报信息进行共享，以及如何对共享平台中构建的共享区块中的评级参数进行更新。The above describes in detail the construction of the sharing platform based on the threat intelligence information provided by the threat intelligence source. The following will describe in detail how to share the threat intelligence information based on the sharing platform, and how to rate the rating in the shared block constructed in the sharing platform. The parameters are updated.

进一步的，基于实施例一，参照图5，图中示出了本公开实施例提供的信息共享方法的流程示意图之二。如图5所示，所述步骤103之后，该方法还可以包括如下步骤：Further, based on the first embodiment, referring to FIG. 5, the figure shows the second schematic flowchart of the information sharing method provided by the embodiment of the present disclosure. As shown in Figure 5, after the step 103, the method may further include the following steps:

步骤501，接收第二区块链节点针对目标威胁情报信息发送的调用信息。Step 501: Receive the call information sent by the second blockchain node for the target threat intelligence information.

这里，从功能上划分，所述第二区块链节点为调用威胁情报信息的区块链节点，可以称之为威胁情报调用者，也可以称之为威胁情报共享者。Here, in terms of functions, the second blockchain node is a blockchain node that calls threat intelligence information, and can be called a threat intelligence caller or a threat intelligence sharer.

所述第二区块链节点通常与第一区块链节点不同，但也存在相同的情况，如检测类产品厂家即可以作为威胁情报源提供威胁情报信息，又可以作为威胁情报调用者调用其他威胁情报源提供的威胁情报信息。The second blockchain node is usually different from the first blockchain node, but the same situation exists. For example, the detection product manufacturer can provide threat intelligence information as a threat intelligence source, and can also call others as a threat intelligence caller. Threat intelligence information provided by threat intelligence sources.

所述第二区块链节点对所述目标威胁情报信息的共享记录进行调用，生成调用信息；并调用上传接口，将所述调用信息上传至电子设备。相应的，该电子设备接收所述调用信息。The second blockchain node calls the shared record of the target threat intelligence information to generate call information; and calls the upload interface to upload the call information to the electronic device. Correspondingly, the electronic device receives the call information.

步骤502，基于所述调用信息，对目标共享区块中的评级参数进行更新，所述目标共享区块为基于所述目标威胁情报信息生成的时间轴上最新的共享区块，所述评级参数为对共享所述目标威胁情报信息的区块链节点进行评价的参数。 Step 502, based on the call information, update the rating parameters in the target shared block, the target shared block being the latest shared block on the time axis generated based on the target threat intelligence information, the rating parameter It is a parameter for evaluating the blockchain nodes sharing the target threat intelligence information.

所述评级参数可以包括威胁情报源可信度、威胁情报源贡献率和威胁情报源的级别。威胁情报源可信度，是威胁情报源的可信度相关信息，威胁情报源贡献率，是威胁情报源的贡献率相关信息，威胁情报源的级别是威胁情报源的等级相关信息。The rating parameters may include the credibility of the threat intelligence source, the contribution rate of the threat intelligence source, and the level of the threat intelligence source. Threat intelligence source credibility refers to the credibility-related information of the threat intelligence source, the contribution rate of threat intelligence source is the contribution rate related information of the threat intelligence source, and the level of the threat intelligence source is the level-related information of the threat intelligence source.

所述威胁情报源的级别可以通过威胁情报源可信度和威胁情报源贡献率来计算，比如，当威胁情报源可信度在10％～20％之间，且威胁情报源贡献率在10％～20％之间时，所述威胁情报源的级别处于第五等级。当然，上述设置威胁情报源的级别的方式只是作为一种示例，并不能用来限制威胁情报源的级别设置方式。The level of the threat intelligence source can be calculated by the credibility of the threat intelligence source and the contribution rate of the threat intelligence source. For example, when the credibility of the threat intelligence source is between 10% and 20%, and the contribution rate of the threat intelligence source is 10%. %-20%, the level of the threat intelligence source is at the fifth level. Of course, the above method of setting the level of threat intelligence sources is just an example, and cannot be used to limit the method of setting the level of threat intelligence sources.

电子设备接收到调用信息之后，基于所述调用信息中的目标威胁情报信息，查询共享所述目标威胁情报信息的区块链节点，即查询所述目标威胁情报信息源于哪个威胁情报源。After receiving the calling information, the electronic device queries the blockchain nodes sharing the target threat intelligence information based on the target threat intelligence information in the calling information, that is, queries the threat intelligence source from which the target threat intelligence information comes.

首先，基于所述调用信息中的目标威胁情报信息，查询获得目标共享区块，基于目标共享区块，获得共享所述目标威胁情报信息的区块链节点，同时获得评级参数。First, based on the target threat intelligence information in the calling information, query and obtain the target shared block, and based on the target shared block, obtain the blockchain nodes that share the target threat intelligence information, and obtain the rating parameters at the same time.

然后，基于所述调用信息，对所述评级参数进行更新。Then, based on the calling information, the rating parameters are updated.

所述基于所述调用信息，对目标共享区块中的评级参数进行更新的步骤包括：The step of updating the rating parameters in the target shared block based on the calling information includes:

其中，所述目标参数包括以下至少一项：Wherein, the target parameter includes at least one of the following:

调用次数；Number of calls

可以根据统计调用信息的个数，来确定所述调用次数。另外，所述调用信息中也可以包括第二区块链节点针对所述目标威胁情报信息的调用进行评价的评价参数，比如，可以设置反馈机制，给威胁情报调用者提供反馈接口，以反馈威胁情报信息的质量高低；相应的，获取调用信息中的评价参数。The number of invocations can be determined according to the number of statistical invocation information. In addition, the calling information may also include evaluation parameters used by the second blockchain node to evaluate the calling of the target threat intelligence information. For example, a feedback mechanism may be set to provide a feedback interface for threat intelligence callers to feed back threats. The quality of the intelligence information is high or low; accordingly, the evaluation parameters in the calling information are obtained.

具体的，有以下三种方式对所述评级参数进行更新。Specifically, there are the following three ways to update the rating parameters.

第一种：基于第二区块链节点对目标威胁情报信息的调用次数，对所述评级参数进行更新。The first method is to update the rating parameters based on the number of times the second blockchain node calls the target threat intelligence information.

比如，调用次数达到预设值时，其评级参数相应增加预设百分比，举个例子来说，调用次数达到1时，其评级参数相应增加1％。For example, when the number of calls reaches a preset value, the rating parameter is increased by a preset percentage. For example, when the number of calls reaches 1, the rating parameter is increased by 1%.

第二种：所述第二区块链节点针对所述目标威胁情报信息的调用进行评价的评价参数，对所述评级参数进行更新。The second type: the evaluation parameter of the second blockchain node for evaluating the call of the target threat intelligence information, and the evaluation parameter is updated.

比如，评价参数指示所述目标威胁情报信息有用时，其评级参数相应增加预设百分比；评价参数指示所述目标威胁情报信息无用时，其评级参数相应降低预设百分比。For example, when the evaluation parameter indicates that the target threat intelligence information is useful, its rating parameter is correspondingly increased by a preset percentage; when the evaluation parameter indicates that the target threat intelligence information is not useful, its rating parameter is correspondingly reduced by a preset percentage.

第三种：基于第二区块链节点对目标威胁情报信息的调用次数和，所述第二区块链节点针对所述目标威胁情报信息的调用进行评价的评价参数，对所述评级参数进行更新。The third type: based on the number of calls of the target threat intelligence information by the second blockchain node and the evaluation parameters for the second blockchain node to evaluate the calling of the target threat intelligence information, the rating parameters are evaluated Update.

比如，根据指示目标威胁情报信息有用的评价参数的个数和调用次数的比值，对所述评级参数进行更新，比值越大，评级参数相应增加的越多。For example, the rating parameter is updated according to the ratio of the number of evaluation parameters that indicate the usefulness of the target threat intelligence information and the number of calls. The larger the ratio, the more the rating parameter increases accordingly.

步骤503，在更新的评级参数被第二共识算法共识的情况下，基于所述目标共享区块和所述更新的评级参数，生成第二共享区块。Step 503: In the case where the updated rating parameters are agreed by the second consensus algorithm, a second shared block is generated based on the target shared block and the updated rating parameters.

所述第二共识算法可以与第一共识算法相同，也可以不同，这里不做限制。The second consensus algorithm may be the same as or different from the first consensus algorithm, and there is no restriction here.

这里，在更新评级参数之后，基于第二共识算法，对更新的评级参数进行共识，共识之后，对更新的评级参数进行记录，可以记录更新评级参数的时间，以在区块链中实现对区块的同步。Here, after updating the rating parameters, based on the second consensus algorithm, a consensus is made on the updated rating parameters. After the consensus, the updated rating parameters are recorded, and the time when the rating parameters are updated can be recorded, so as to realize the regionalization in the blockchain. Synchronization of blocks.

记录更新的评级参数之后，即可基于所述目标共享区块和所述更新的评级参数，按照共享区块构建的结构特性，生成第二共享区块。After recording the updated rating parameters, based on the target shared block and the updated rating parameters, a second shared block can be generated according to the structural characteristics of the shared block construction.

应当说明的是，所述第二共享区块与目标共享区块可以仅评级参数不同。It should be noted that the second shared block and the target shared block may differ only in rating parameters.

步骤504，在所述第二共享区块被接收所述第二共享区块的多个区块链节点共识的情况下，将所述第二共享区块写入至所述区块链中。Step 504: In the case where the second shared block is received by the consensus of multiple blockchain nodes of the second shared block, write the second shared block into the blockchain.

电子设备生成第二共享区块之后，会广播该第二共享区块。具体的，将第二共享区块发送给与第二区块链节点同类型的所有区块链节点，这些区块链节点接收到第二共享区块后，会对第二共享区块进行共识，共识通过之后，将结果发送给该电子设备。After the electronic device generates the second shared block, it will broadcast the second shared block. Specifically, the second shared block is sent to all blockchain nodes of the same type as the second blockchain node. After these blockchain nodes receive the second shared block, they will reach a consensus on the second shared block. After the consensus is passed, the result is sent to the electronic device.

在所述第二共享区块被多个区块链节点共识通过的情况下，将所述第二共享区块写入至区块链中。In the case where the second shared block is approved by a consensus of multiple blockchain nodes, the second shared block is written into the blockchain.

应当说明的是，将所述第二共享区块写入至区块链中的前提条件，即第二共享区块被区块链节点共识通过的个数可以根据具体情况进行设置，可以设置成相对所有区块链节点个数的预设百分比，如50％，也可以设置成预设数值，如6个。总之，只要所述第二共享区块被预设个数的区块链节点共识通过后，电子设备即会将所述第二共享区块写入至区块链中。It should be noted that the prerequisite for writing the second shared block to the blockchain, that is, the number of second shared blocks that are passed by the consensus of the blockchain nodes can be set according to the specific situation, and can be set to The preset percentage relative to the number of all blockchain nodes, such as 50%, can also be set to a preset value, such as 6. In short, as long as the second shared block is approved by the consensus of a preset number of blockchain nodes, the electronic device will write the second shared block into the blockchain.

本公开实施例中，通过在区块链中的共享区块中设置评级参数，并通过第二区块链节点针对目标威胁情报信息发送的调用信息，对评级参数进行更新，In the embodiment of the present disclosure, the rating parameters are updated by setting the rating parameters in the shared block in the blockchain, and using the calling information sent by the second blockchain node for the target threat intelligence information,

从而能够根据该评级参数，确定威胁情报源的可信度、贡献度和级别，解决威胁情报源众多，而使威胁情报调用者无法有效判定威胁情报源是否可信，贡献率高低的问题。同时，可以设置反馈机制，为威胁情报调用者反馈共享的威胁情报信息的质量高低，这样，能够解决针对威胁情报源所提供的威胁情报信息的质量高低没有对应的反馈机制的问题。进而能够有利于整个威胁情报生态的闭环持续有效开展。Therefore, the credibility, contribution and level of threat intelligence sources can be determined according to the rating parameters, and the problem of numerous threat intelligence sources can be solved, so that threat intelligence callers cannot effectively determine whether the threat intelligence source is credible and the contribution rate is high or low. At the same time, a feedback mechanism can be set up to feed back the quality of the threat intelligence information shared to the threat intelligence caller. In this way, it can solve the problem that there is no corresponding feedback mechanism for the quality of the threat intelligence information provided by the threat intelligence source. In turn, it can be beneficial to the continuous and effective development of the closed loop of the entire threat intelligence ecosystem.
