实施方式
为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合本申请实施例中的附图，对本申请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申请技术方案的一部分实施例，而不是全部的实施例。基于本申请文件中记载的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请技术方案保护的范围。
下面对本申请实施例中涉及的部分概念进行介绍。
智能合约：即Smart contract，是一种旨在以信息化方式传播、验证或执行合同的计算机协议。智能合约允许在没有第三方的情况下进行可信交易，这些交易可追踪且不可逆转。
以太坊：即Ethereum，是一个开源的有智能合约功能的公共区块链平台，通过其专用加密货币以太币Ether提供去中心化的虚拟机(“以太虚拟机”Ethereum Virtual Machine)来处理点对点合约。
众包：是指把过去由员工执行的工作任务，以自由自愿的形式外包给非特定的(而且通常是大型的)大众网络的做法。
密码破解：是指使用暴力枚举的方式，构造或者使用现有的字典文件，对给定的密码哈希值进行尝试，还原出密码原文的攻击方法。
区块链技术：是指利用块链式数据结构来验证与存储数据、利用分布式节点共识算法来生成和更新数据、利用密码学的方式保证数据传输和访问的安全、利用由自动化脚本代码组成的智能合约来编程和操作数据的一种全新的分布式基础架构与计算方式。
哈勃分析***:是一种安全辅助平台，用户可以通过简单的操作，上传样本并得知样本的基本信息、可能产生的行为、安全等级等等信息，从而更便捷地识别恶意文件。
相关技术中，任务发布方可在网络平台发布公开邀约任务，网络平台中的任务完成方完成公开邀约任务之后，若任务发布方对任务完成方的完成质量不满意，可能存在不支付任务完成方或不按照约定支持任务完成方的情况，就会造成任务完成方与任务发布方之间的不信任问题，若平台或第三方介入实施仲裁，也会存在发布方与任务完成方不信任第三方或平台仲裁结果，所以，相关技术中在执行任务过程，存在发布方和任务完成方之间的不信任的问题。
鉴于此，本申请实施例提供了一种任务处理方法，该方法在接收任务发布方设备发布的任务以及与执行所述任务对应的电子资源时，向区块链网络发送接收到的任务以及电子资源，即将任务发布方设备发布的任务以及与执行该任务对应的电子资源，作为智能合约构造函数的输入参数发送给所述区块链网络用以构造与任务对应的智能合约，并在获得任务应邀方设备在执行任务后针对该任务发送的执行结果时，将执行结果发送给所述区块链网络，进而可以通过所述区块链网络根据智能合约验证执行结果以及根据验证结果自动执行电子资源的分配，由于所述区块链网络的智能合约自动化履约，规则透明，逻辑透明，任务实施产生的数据均存储在区块链上，公开且无法篡改，所以消除了任务发布方和任务应邀方之间的不信任关系，也不需要第三方介入实施仲裁，所以也简化了任务执行的复杂度，同时抵御了伪造结果的非法操作。
进一步的，由于该方法中在任务被成功执行完成之后，由所述区块链网络按照智能合约的约定分配给任务应邀方设备相应的资源，保证了任务应邀方的获 取对应报酬的权益，能够吸引更多的任务应邀方投入更多的计算资源执行任务，所以，也提升了任务的执行效率和成功率。
需要说明的是，本申请实施例中的任务可以是任何能够在网络平台上发布、且可由网络平台用户自由选择并利用其计算资源执行的公开邀约任务，这样的公开邀约任务如为进行密码安全强度评估而公开发布的密码破解任务，如为需求答案而公开发布的疑难问题任务等等。
本申请实施例中的任务处理方法可以应用于如图1所示的应用场景，该应用场景中包括第一用户终端10、第二用户终端11、任务控制计算设备以及区块链网络。
在一些实施例中，如图1中所示，任务控制计算设备可以为任务控制服务器12，任务控制服务器12可以是一台服务器，也可以是若干台服务器组成的服务器集群或云计算中心。
区块链网络是由多个节点参与的分布式数据库***，包括多个节点，该区块链网络中包括至少一个具有智能合约功能的公共区块链。在图1中所示的实施例中，该区块链网络由多个节点构成，该区块链网络中的节点13支持具有智能合约功能的公共区块链。其中，在区块链网络中具有智能合约功能的公共区块链如以太坊、超级账本Hyperledger、RSK等。
第一用户终端10与第二用户终端11可以为具备网络通讯能力的电子设备，该电子设备可以是智能手机、平板电脑、便携式个人计算机或其他智能终端等等。
在一些实施例中，任务控制服务器12可以与第一用户终端10、第二用户终端11以及所述区块链网络中的任一节点13通过网络进行通讯，其中，网络可以为局域网、广域网或移动互联网等通信网络中的任意一种。
第一用户终端10与第二用户终端11中安装有任务控制服务器12支持的客户端。第一用户终端10与第二用户终端11可以基于各自安装的客户端与任务控制服务器12进行通讯。
在该场景中，第一用户终端10可以作为任务发布方设备，通过其安装的客户端在任务控制服务器12中发布任务。第二用户终端11可以作为任务应邀方设备，通过其安装的客户端从任务控制服务器12申请任务进行破解，当然，第一用户终端10也可以为任务应邀方设备，申请任务进行破解，第二用户终端11可以为任务发布方设备，发布任务。
需要注意的是，上文提及的应用场景仅是为了便于理解本申请的精神和原理而示出，本申请实施例在此方面不受任何限制。相反，本申请实施例可以应用于适用的任何场景。
下面结合图1所示的应用场景，对本申请实施例提供的任务控制方案进行说明。
请参考图2A，本申请实施例提供了一种任务控制***，该***包括任务控制子***20以及智能合约控制子***21，其中，任务控制子***20可以理解为图1所示应用场景中的任务控制服务器12，智能合约控制子***21可以理解为图1所示应用场景中的支持具有智能合约功能的公共区块链。
在本申请实施例中，任务控制子***20用于在接收到任务发布方22发布的任务以及与执行任务对应的电子资源时，从智能合约控制子***21调用智能合约构造函数，并将任务发布方发布的任务以及与执行该任务对应的电子资源，作为智能合约构造函数的输入参数发送给智能合约控制子***21。
智能合约控制子***21用于根据接收到的任务以及与执行该任务对应的电子资源，构造与任务对应的智能合约；以及接收任务控制子***20发送的执行结果，并根据所述智能合约对执行结果进行验证，并根据验证结果向任务应邀方设备转移电子资源，该执行结果为任务应邀方设备23实施任务后，针对该任务发送给任务控制子***20的。
结合图1所示的应用场景以及图2A所示的任务控制***，本申请实施例提供了一种任务处理方法，由图1所示应用场景中的任务控制服务器12执行。不失一般性的假设，图1中的第一用户终端10为任务发布方设备，第二用户终端11为任务应邀方设备。如图2B所示，该任务处理方法，包括以下步骤：
S201，接收任务发布方设备发布的任务以及与执行所述任务对应的电子资源。
在一些实施例中，任务控制服务器接收任务发布方通过任务发布方设备上的客户端发布的任务和执行该任务对应的电子资源。
其中，电子资源是指区块链中用来支付交易手续费和运算服务费的媒介，区块链中不同公共区块链平台可以有属于该平台的电子资源，如以太坊区块链中的以太币即Ether，即以太坊区的代币(电子资源)，它是以太坊上用来支付交易 手续费和运算服务费的媒介。
S202，向区块链网络发送所述任务以及所述电子资源，以使所述区块链网络构造与所述任务对应的智能合约。
在一些实施例中，任务控制服务器可以向所述区块链网络发送智能合约调用指令，以使其反馈被调用的智能合约构造函数；接收所述区块链网络返回的智能合约构造函数；并将所述任务以及所述电子资源作为所述智能合约构造函数的输入参数发送给所述区块链网络，以使其根据接收到的输入参数，构造与任务发布方设备发布的任务对应的智能合约。
需要说明的是，可以向所述区块链网络中的任一节点发送智能合约调用指令，根据其反馈的智能合约构造函数，将所述任务以及所述电子资源作为所述智能合约构造函数的输入参数发送给所述区块链网络的该节点，该节点根据所述任务以及所述电子资源构造所述任务对应的智能合约后，会将该智能合约同步更新至所述区块链网络中的其他的各个节点。这样，所述区块链网络中的任一节点在接收到任务控制服务器转发的任务应邀方设备的执行结果后，都可以根据所述智能合约对该执行结果进行验证，并根据验证结果完成电子资源的转移。
S203，接收任务应邀方设备在执行所述任务后发送的所述任务对应的执行结果。
在一些实施例中，在接收任务应邀方实施所述任务后发布的执行结果之前，任务控制服务器将所述任务放入任务池；接收所述任务应邀方设备发送的申请执行任务请求；从所述任务池选择任务；并将所选择的任务发送给所述任务应邀方设备执行。
在一些实施例中，可以按照设定的条件，为所述任务池中的任务设置执行优先级，在从所述任务池选择任务时，可以从所述任务池选择执行优先级最高的任务。其中，所述设定的条件包括：电子资源的额度，其中，额度越高则执行优先级越高；或者任务的发布时间，其中，发布时间越早则执行优先级越高。
在一些实施例中，任务应邀方设备在向任务控制服务器发送申请执行任务请求时，可以将申请执行的任务的任务标识携带在该申请执行任务请求中。从所述任务池选择任务时，可以在从所述任务池中，根据所述申请执行任务请求中携带的申请执行的任务标识，选择所述任务标识对应的任务。
在一些实施例中，从所述任务池选择任务之后，所述任务控制服务器还可以向所述区块链网络发送智能合约调用请求，以调用所选择的任务对应的智能合约，并确认所述智能合约是否有效；如果确认所述智能合约有效，则将所选择的任务发送给所述任务应邀方设备执行；以及如果确认所述智能合约无效，则从所述任务池中删除对应的任务，并从所述任务池中重新选择任务。
S204，将所述执行结果发送给区块链网络，以使其根据所述智能合约对所述执行结果进行验证，并根据验证结果向任务应邀方设备转移所述电子资源。
如前所述，所述区块链网络中的第一节点构造与任务发布方设备发布的任务对应的智能合约后，会将该智能合约同步更新至所述区块链网络中的其他的各个节点。因此，所述区块链网络中的第二节点在接收到任务控制服务器转发的任务应邀方设备的执行结果后，也可以根据所述智能合约对该执行结果进行验证，并根据验证结果完成电子资源的转移，所述第二节点可以与第一节点相同，也可以不同。
在一些实施例中，所述任务应邀方设备在完成任务之后，通过第二用户终端上的客户端将执行结果发送至所述任务控制服务器，所述任务控制服务器将接收到的所述执行结果发送给所述区块链网络之后，还可以接收所述区块链网络发送的合约已履行的确认消息；所述确认消息为所述区块链网络在根据所述验证结果向任务应邀方设备转移所述电子资源后生成的；从所述任务池中删除对应的任务。
在一些实施例中，所述向所述区块链网络发送所述电子资源包括：向所述区块链网络发送所述任务发布方设备的第一账户地址和所述电子资源的数量；所述方法进一步包括：将所述任务应邀方设备的第二账户地址发送给所述区块链网络；其中，当所述验证结果正确时，所述区块链网络将所述电子资源从所述第一账户地址转移到所述第二账户地址，进而使任务应邀方设备获取对应的报酬。
在本发明实施例中，在接收任务发布方设备发布的任务以及与执行所述任务对应的电子资源时，向区块链网络发送接收到的任务以及电子资源，即将任务发布方设备发布的任务以及与执行该任务对应的电子资源，作为智能合约构造函数的输入参数发送给所述区块链网络用以构造与任务对应的智能合约，并在获得任务应邀方设备在执行任务后针对该任务发送的执行结果时，将执行结果发送给 所述区块链网络，进而可以使所述区块链网络根据智能合约验证执行结果以及根据验证结果自动执行电子资源的分配，由于区块链网络中的节点中的智能合约自动化履约，规则透明，逻辑透明，任务实施产生的数据均存储在区块链上，公开且无法篡改，所以消除了任务发布方和任务应邀方之间的不信任关系，也不需要第三方介入实施仲裁，所以也简化了任务执行的复杂度，同时抵御了伪造结果的非法操作。
基于同一发明构思，本申请实施例提供了一种任务处理方法，为叙述方便，在下文中以任务具体为密码破解任务，任务控制服务器为众包服务器为例，结合上述应用场景，对本申请实施例中的任务处理方法进行详细叙述。
如图3A所示，本申请实施例中的任务处理方法，由任务控制服务器执行，也即由众包服务器执行，包括：
步骤301：接收任务发布方设备发布的任务以及与执行所述任务对应的电子资源。
在本申请实施例中，众包平台可以理解为由众包服务器实现，众包平台接收任务发布方设备发布的任务以及与执行任务对应的电子资源的方式包括多种，例如，一种方式是：众包平台可先接收任务发布方发送的密码破解任务的发布请求，然后，众包平台查看任务发布方设备是否具有发布任务的权限，若任务发布方设备具有发布任务的权限，向任务发布方设备发送表征任务发布方设备可发布任务的确认信息，任务发布方设备接收到该确认消息之后，再向众包平台发送任务以及与执行任务对应的电子资源。
另一种方式是：任务发布方设备在发布的密码破解任务请求中携带任务以及与执行任务对应的电子资源，众包平台接收该请求，并从该请求中获取携带的任务以及与执行任务对应的电子资源；再一种方式是：任务发布方设备直接在众包平台提供的发布窗口发布任务以及与执行该任务对应的电子资源，进而使众包平台直接接收到任务发布方设备的密码破解任务以及与执行该任务对应的电子资源。
其中，上述列举的前两种方式中众包平台接收密码破解任务请求的方法包括多种，例如，众包平台可在用户交互界面提供用于发布密码破解任务的选项，通过任务发布方设备选择该选项的方式，获得任务发布方设备发布的密码破解任务请求，也可以通过接收任务发布方设备以语音输入方式或文本输入方式发布的 密码破解任务请求。
其中，密码破解任务中的密码，可以为任何需要进行密码安全强度评估的密码，这样的密码如网络环境中部署的应用服务的密码、服务器的密码、文件的密码等等。密码破解任务中的密码可以是基于哈希函数加密的密码，也可以是基于其他加密技术进行加密的密码。
步骤302：向区块链网络中发送智能合约调用指令，以使其反馈被调用的智能合约构造函数。
在本申请实施例中，步骤302中的区块链网络可以理解为具有智能合约功能的公共区块链。在实际应用中，区块链网络中可以包括一个或多个具有智能合约功能的公共区块链，不同公共区块链可拥有与不同的智能合约构造函数，也可以具有通用的智能合约构造函数，上述公共区块链可以是以太网坊等。众包平台在接收到任务发布方设备发布的密码破解任务请求时，可以从区块链网络包括的多个公共区块链中，选择众包平台支持的一个公共区块链，用于构建与密码破解任务对应的智能合约。
在本申请实施例中，如果区块链网络中不同公共区块链拥有不同的智能合约构造函数，也即不同公共区块链拥有与其对应的智能合约构造函数，众包平台从其支持的公共区块链中选择一个公共区块链，并向选择的公共区块链发送智能合约调用指令，以使其反馈被调用的智能合约构造函数；如果区块链中不同公共区块链拥有通用的智能合约构造函数，那么，众包平台可向区块链网络发送智能合约调用指令，以使其反馈被调用的区块链中通用的智能合约构造函数。
在此，以区块链网络中不同公共区块链拥有与各自对应的智能合约构造函数为例，那么，众包平台可从其支持的公共区块链中选择的一个公共区块链，并向选择的公共区块链发送智能合约调用指令，以使其反馈被调用的智能合约构造函数。不失一般性假设，本申请中的区块链网络中的各个节点都具有智能合约功能，因此，在向区块链网络发送智能合约调用指令时，可以向图1中所示的所述区块链网络中的任一节点13发送智能合约调用指令。该节点13根据所述任务以及所述电子资源构造所述任务对应的智能合约后，会将该智能合约同步更新至所述区块链网络中的其他的各个节点。这样，所述区块链网络中的任一节点在接收到任务控制服务器转发的任务应邀方设备的执行结果后，都可以根据所述智能合约对该执行结果进行验证，并根据验证结果完成电子资源的转移。
步骤303：根据智能合约构造函数，向所述区块链网络发送任务发布方发布的任务以及与执行该任务对应的电子资源。
所述众包平台根据调用的智能合约构造函数，可将任务发布方设备发布的密码破解任务以及与破解密码破解任务对应的电子资源，作为该智能合约构造函数的输入参数发送给所述区块链网络，所述区块链网络根据接收到的输入参数，构造与任务发布方发布的密码破解任务对应的智能合约。
其中，电子资源是指区块链中用来支付交易手续费和运算服务费的媒介，区块链中不同公共区块链平台可以有属于该平台的电子资源，如以太坊区块链中的以太币即Ether，即以太坊区的代币(电子资源)，它是以太坊上用来支付交易手续费和运算服务费的媒介。
步骤304：接收所述区块链网络发送的智能合约构造成功消息。
在本申请实施例中，在所述区块链网络构造与密码破解任务对应的智能合约之后，可以向众包平台发送智能合约构造成功的消息，还可以在该消息中还可携带构造的智能合约的地址信息，用于众包平台在后续过程中根据该地址信息调用或查看该智能合约。因此，本申请实施例中众包平台还可以执行步骤304即接收到所述区块链网络发送的智能合约构造成功的消息。
步骤305：将任务放入任务池。
在本申请实施例中，众包平台可设置任务池，用于存放待破解的密码破解任务以供破解者从任务池中选择待破解的密码破解任务。众包平台接收到所述区块链网络反馈的智能合约构造成功消息后，可将该智能合约对应的密码破解任务放入任务池中，以供破解者从任务池中选择待破解的密码破解任务。
步骤306：按照设定的条件，为任务池中的任务设置执行优先级。
在本申请实施例中，众包平台还可以按照设定的条件，为任务池中的密码破解任务设置破解优先级，其中，设定的条件可以包括密码破解任务对应的电子资源的额度或密码破解任务在众包平台的发布时间，例如，众包平台可根据密码破解任务对应的电子资源的额度从高到低的顺序，设定任务池中每个密码破解任务的破解优先级，额度越高破解优先级越高，当然，众包平台可根据密码破解任务在众包平台的发布时间从早到晚的顺序，设定任务池中每个密码破解任务的破解优先级，发布时间越早则破解优先级越高，也可以结合电子资源的额度及发布时间进行破解优先级排序。
在本申请实施例中，如图3B所示，众包平台还可以按照破解优先级的从高到低的顺序，依次显示任务池中的密码破解任务，图3B中按照各密码破解任务的奖金金额即电子资源额度，从高到低进行破解优先级排序并显示，当然，也可以选择按照发布时间，或结合电子资源的额度及发布时间进行破解优先级排序并显示。
步骤307：接收所述任务应邀方设备发送的申请执行任务请求。
在本申请实施例中，任务应邀方设备可以向众包平台发送申请执行任务池中的密码破解任务的请求，即申请对任务池中的密码破解任务进行破解，其中，任务应邀方设备可以在该请求中直接携带所要选择的密码破解任务。
步骤308：从任务池选择任务。
在本申请实施例中，当上文中的申请执行任务请求携带任务应邀方设备所要选择的密码破解任务，众包平台可以在任务池中为任务应邀方设备选择携带的密码破解任务；当上文中的申请执行任务请求未携带任务应邀方设备所要选择的密码破解任务，可由众包平台从任务池中为任务应邀方设备选择一个密码破解任务进行破解，例如，在众包平台对任务池中的密码破解任务设置了破解优先级时，众包平台可以为任务应邀方设备选择当前破解优先级最高的密码破解任务，当然，众包平台也可以从任务池的密码破解任务中为任务应邀方设备随机选择一个密码破解任务。
步骤309：确定所选择的任务对应的智能合约是否有效。
在本申请实施例中，在从任务池选择任务之后，还可以从所述区块链网络中调用所选择的任务对应的智能合约，以确认该智能合约是否有效。
若确认该智能合约无效，则从所述任务池中删除对应的任务，并重新执行上述步骤308，即从所述任务池中重新选择任务。
其中，智能合约无效的情况包括：众包平台从所述区块链网络未成功调用到智能合约，则可确定该智能合约无效，或众包平台从所述区块链网络成功调用到该智能合约，但该智能合约由于其对应的密码破解任务已被执行等原因导致其无效。
在一些实施例中，可以通过密码破解任务对应的智能合约提供的接口函数，并基于智能合约在所述区块链网络中的地址信息调用该智能合约。其中，智能合约有效表示智能合约中的密码破解任务还未被成功破解并支付，智能合约无效表 示智能合约中的密码破解任务已被成功破解且已支付或因为其他原因被强制终止。
若确认该智能合约有效时，执行
步骤310：将所选择的任务发送给任务应邀方设备执行。
在众包平台成功调用到所选择的密码破解任务对应的智能合约时，可从该智能合约中获取密码破解任务，然后将获取的密码破解任务发送给任务应邀方设备进行破解。
步骤311：接收任务应邀方设备在执行任务后针对该任务发送的执行结果。
在本申请实施例中，任务应邀方设备获得众包平台发送的密码破解任务之后，可使用任务应邀方设备的计算资源，并基于密码暴力枚举破解工具对密码破解任务进行破解，其中，密码暴力枚举破解工具例如hashcat，对密码破解任务进行枚举破解。其中，hashcat系列软件在硬件上支持使用CPU、NVIDIA GPU、ATI GPU来进行密码破解，并且支持将几台机器连接起来，进行分布式破解作业。
例如破解方在得到任务后，可以使用hashcat工具中“./hashcat-cli32.exe -m 500 -a 0 hash_string passwordlist.txt”命令，对密码破解任务进行暴力破解，该命令表示对hash_string即密码破解任务进行字典模式***破解(其中，-a 0为指定使用的字典模式)，hash_string使用md5加密方式(-m 500，为指定的hash类型)，使用的字典文件为passwordlist.txt。
若任务应邀方设备成功破解密码破解任务，可在将破解结果发送给众包平台，众包平台接收该破解结果之后，执行：
步骤312：将执行结果发送给所述区块链网络，以使所述区块链网络根据所述智能合约对执行结果进行验证，并根据验证结果支付电子资源。
如前所述，所述区块链网络中的任一节点构造与任务发布方设备发布的任务对应的智能合约后，会将该智能合约同步更新至所述区块链网络中的其他的各个节点。因此，所述区块链网络中的任一节点在接收到任务控制服务器转发的任务应邀方设备的执行结果后，也可以根据所述智能合约对该执行结果进行验证，并根据验证结果完成电子资源的转移。
其中，执行结果即为上文中的破解结果，在具体实践过程中，众包平台可通过调用被成功破解的密码破解任务对应的智能合约的接口，基于该接口将破解结果发送给所述区块链网络中对应的智能合约，以使所述区块链网络根据所述智 能合约对破解结果进行验证，并根据验证结果支付电子资源。
下面介绍所述区块链网络根据所述智能合约验证破解结果以及根据验证结果支付电子资源的具体过程，如图4所示，该过程包括：
步骤401：接收执行结果；
步骤402：验证执行结果是否正确，若是，则执行步骤403，否则执行步骤407；
步骤403：根据所述区块链网络接收到执行结果的时间，确定执行结果是否为所述任务对应的第一个验证正确的结果，若是，则执行步骤404，否则执行步骤406；
在一些实施例中，如前所述，众包平台可通过调用被成功破解的密码破解任务对应的智能合约的接口，基于该接口将破解结果发送给所述区块链网络中对应的智能合约，因此，所述区块链网络接收到执行结果的时间也可以是所述区块链网络中的智能合约接收到执行结果的时间。
步骤404：将电子资源从第一账户地址转到第二账户地址；其中，第一账户地址为任务发布方设备的电子资源在区块链网络中的地址，第二账户地址为任务应邀方设备的电子资源在区块链网络中的地址；
步骤405：向任务控制服务器发送支付成功的信息。
步骤406：向任务控制服务器发送表征执行结果不是所述任务对应的第一个验证成功结果的信息；
步骤407：向任务控制服务器发送表征执行结果验证未通过的信息。
在本申请实施例中，所述区块链网络在接收到众包平台输入的破解结果时，可对该破解结果进行验证，破解结果即为图4中的执行结果，所述区块链网络可通过智能合约调用区块链中的具有密码验证的功能模块，例如可调用具有oraclize技术的功能模块，向该功能模块发起一个oraclize请求，并在oraclize请求中携带破解结果以及密码hash值即密码破解任务中的密码，其中，携带的破解结果又可称为明文。该功能模块基于oraclize请求中携带的破解结果以及密码hash值，在orcalize的数据源中将明文使用相同的算法加密成hash值，最后比较计算出的hash值与传递进来的密码hash值是否一致，如果一致则验证成功，若不一致则验证失败。该功能模块在完成上述验证之后，根据验证结果，向所述区块链网络中的智能合约反馈验证成功的信息或反馈验证失败的信息。
若所述区块链网络接收到该功能模块反馈的验证成功的信息，可根据破解结果输入智能合约的输入时间，确定破解结果是否为针对其对应的密码破解任务的第一个验证成功的结果，若是，所述区块链网络可将任务发布方设备转移密码破解任务提供的电子资源，从任务发布方设备在区块链网络中的电子资源的第一账户地址转到任务应邀方设备在区块链网络中电子资源的第二账户地址，进而完成支持。
所述区块链网络可以向众包平台发送支付成功的信息，以便众包平台删除任务池中与所述智能合约对应的密码破解任务，众包平台也可向任务应邀方设备发送破解成功以及支持成功的信息。所述区块链网络接收到所述智能合约反馈的交易完成，请求关闭交易(即删除交易)的信息后，删除该智能合约。
若所述区块链网络确定破解结果不是密码破解任务对应的第一个验证成功的结果(例如，相差较小时间间隔内，存在多个任务应邀方设备对发布该密码破解任务的破解结果，其中已验证其他任务应邀方设备中的某个任务应邀方设备的破解结果正确且该结果是第一个验证成功的结果，而此时智能合约还未关闭)，可向众包平台发送表征破解结果不是密码破解任务对应的第一个验证成功的结果，众包平台可向任务应邀方设备发送支付失败的信息，也可在支付失败的信息中携带表征支付失败是因为其不是第一个验证成功的原因。
在本申请实施例中，在步骤402中若所述区块链网络验证破解结果不是正确的结果，可向众包平台发送表征破解结果验证失败的信息，以便众包平台向任务应邀方设备反馈破解失败的信息，并继续等待其他破解者破解智能合约中的密码破解任务。
在本申请实施例中，还可以设置智能合约有效时长，若在有效时长内，该智能合约中的密码破解任务未被成功破解，所述区块链网络可无效该智能合约，还可以向众包平台发送该智能合约无效的信息，以便众包平台删除任务池中与该智能合约对应的密码破解任务。
所以，通过上述方法，在本申请实施例中，在接收到任务发布方设备发布的任务请求时，可以从区块链网络调用智能合约构造函数，构造与任务对应的智能合约，由于区块链网络中的智能合约具有自动化履约，执行规则及逻辑透明，结果公开且无法篡改的特征，所以，在任务应邀方设备实施其选择的任务后，由区块链网络根据所述智能合约对其执行结果验证，保证了验证结果的准确性和公 正性，解决了任务发布方与任务应邀方之间就执行结果质量之间的信任问题，且区块链网络可根据验证结果通过智能合约自动执行电子资源的分配，保证报酬能够顺利分配到符合成功完成任务的任务应邀方设备，所以，进一步解决了任务发布方与任务应邀方之间在执行任务过程中的信任问题，同时也不需要第三方介入实施仲裁，简化了任务执行的复杂度，进一步的，由于执行任务过程中结果公开且无法篡改，所以也抵御了伪造结果的非法操作。
进一步的，由于该方法中在任务被成功执行完成之后，由区块链网络通过智能合约按照约定分配给任务应邀方设备，保证了任务应邀方获取对应报酬的权益，能够吸引更多的任务应邀方投入更多的计算资源执行任务，所以，也提升了任务的执行效率和成功率。
下文以区块链网络具体为以太坊，在众包平台中发布的密码破解任务具体为“$1$yQyreloj$VroB091VbXCpywPOTYHcE1”，电子资源具体为以太币为例，来对本申请实施例中的方法进一步说明。
基于众包平台和具有智能合约功能的以太坊的密码破解任务的控制流程可如图5所示，包括：
S1：任务发起终端向众包平台发送密码破解任务的发布请求。
在本申请实施例中，任务发起终端可视为上文中的任务发布方的设备终端，任务发起终端中安装有众包平台应用，当然还可以安装有其他类型的应用，任务发起终端的用户在众包平台应用中进行操作，以申请发布密码破解任务，例如点击众包平台应用对应的用户界面中的任务发布按钮，任务发起终端接收到该操作之后，向众包平台发送密码破解任务请求。
其中，任务发起终端的用户可以为众包平台中的个体用户，也可以为***级用户，例如任务发布方可为哈勃分析***，那么，哈勃分析***可提取IoT固件密码，然后通过任务发起终端向众包平台发送密码破解任务请求，以便将IoT固件密码发布到众包平台中，其中，IoT固件密码为经过哈希函数进行保护的密码。
S2：众包平台确定任务发起终端具有密码破解任务的发布权限，向任务发起终端发送允许发布密码破解任务的消息。
众包平台接收到任务发起终端发送的密码破解任务的发布请求，可对任务发起终端进行密码破解任务发布权限的鉴定，即查看任务发起终端是否具有发布 码破解任务的权限，若具有权限，则向任务发起终端发送允许发布密码破解任务的消息，否则，向任务发起终端发送拒绝其发布密码破解任务的消息。
S3：任务发起终端向众包平台发送密码破解任务以及为执行该密码破解任务支付的电子资源。
任务发起终端接收到上述允许发布密码破解任务的消息之后，可跳转到众包平台应用中用于用户输入任务的用户界面，如图6所示，为本申请实施例中提供的众包平台应用中用于用户输入任务的用户界面的示意图，在该应用界面包括选项“_mission”用于输入具体的密码破解任务，选项“Value”用于输入为破解密码破解任务支付的电子资源即以太币，当然还可以包括其他选项如用于输入的发布密码破解任务的钱包地址的选项“Account”，以及确定密码破解任务相关信息输入完成的选项“transact”等。
用户在该用户界面的选项“_mission”中输入的密码破解任务为“$1$yQyreloj$VroB091VbXCpywPOTYHcE1”，在选项“Value”中输入为破解该密码破解任务支付的50以太币，还可以在选项“Account”输入用户以太币所在的钱包地址，当然，任务发起终端也可以自动获取用户以太币所在的钱包地址，并在选项“Account”中现实。待上述信息输入完成之后，用户可选择用户界面中的选项“transact”以确定信息输入完成。
任务发起终端接收到用户选择选项“transact”操作之后，可将用户输入的任务以及为执行任务支付的电子资源发送给众包平台，其中，发送的电子资源包括其金额即50以太币以及该50以太币所在的钱包地址。
S4：众包平台向以太坊发送智能合约调用请求，以使其反馈被调用的智能合约构造函数。
众包平台接收到任务发起终端发送的密码破解任务以及为执行密码破解任务支付的电子资源之后，具体可以向以太坊发送智能合约调用指令，以调用以太坊中的智能合约构造函数，智能合约构造函数是以太坊中用于构造智能合约的函数，以太坊根据输入智能合约构造函数中参数，构造对应的智能合约。
S5：众包平台接收到以太坊发送的智能合约构造函数。
S6：众包平台根据智能合约构造函数，将任务发起终端发送的密码破解任务以及电子资源发送给以太坊。
众包平台接收到以太坊发送的智能合约构造函数之后，可将任务发起终端 发送密码破解任务“$1$yQyreloj$VroB091VbXCpywPOTYHcE1”，以及电子资源即50以太币和其所在的钱包地址，作为智能合约构造函数的输入参数发送给以太坊。
S7：以太坊构造与密码破解任务对应的智能合约。
以太坊根据接收到的智能合约构造函数的输入参数，构造与密码破解任务“$1$yQyreloj$VroB091VbXCpywPOTYHcE1”对应的智能合约，其中，构造的智能合约中包括为支付该密码破解任务提供的以太币金额、以太币所在地址、需要破解的密码破解任务本身以及表征该密码破解任务是否有效的参数。
例如图7所示，为以太坊构造的名为“HashHunter”的智能合约，在该智能合约中“owener”表示密码破解任务的需求方即任务发布方，“bounty”为支付密码破解任务的电子资源即以太币，“mission”为需要破解的被哈希保护的密码字符串即密码破解任务，“isActive”表征智能合约是否仍然有效，例如“isActive”取值为1时表征智能合约有效，“isActive”取值为0时表征智能合约无效。
S8：以太坊向众包平台发送智能合约构造成功的信息。
S9：众包平台将构造成功的智能合约对应的密码破解任务放入任务池。
在本申请实施例中，众包平台在接收到以太坊发送的智能合约构造成功的信息时，可将该智能合约对应的密码破解任务放入任务池，以便任务接收终端从任务池中选择需要破解的密码破解任务。
其中，众包平台可按照上文叙述的方式对智能合约对应的密码破解任务进行执行优先级排序后放入任务池，且还可以按照执行优先级排序控制其在任务池中的显示顺序。
S10：任务接收终端向众包平台发送申请执行密码破解任务请求。
在本申请实施例中，任务接收终端可视为上文中的任务应邀方设备，众包平台将构造成功的智能合约对应的密码破解任务放入任务池之后，在任务接收终端的众包平台应用中可显示任务池中的密码破解任务，任务接收终端的用户可从众包平台应用显示的密码破解任务中选择需要破解的密码破解任务，任务接收终端在获得其用户选择需要破解的密码破解任务的操作时，可基于该操作向众包平台发送申请执行密码破解任务的请求。
S11：众包平台从任务池选择密码破解任务。
S12：众包平台向以太坊点发送调用所选择的密码破解任务对应的智能合约 的请求，以确定该智能合约是否有效。
如上文叙述，若在申请执行任务请求中携带任务接收终端用户所选择破解的密码破解任务时，众包平台可以在任务池中选择携带的密码破解任务；若未携带，则众包平台从任务池中为任务接收终端用户选择一个密码破解任务进行破解。在众包平台从任务池中为任务接收终端用户选择密码破解任务之后，还可以调用所选择的密码破解任务对应的智能合约的请求，以便通过确定智能合约中参数“isActive”当前的值，以确定该智能合约是否有效，其中，众包平台可基于智能合约在以太坊的地址信息向以太坊发送调用该智能合约的请求。
S13：众包平台接收以太坊发送的该智能合约相关信息。
S14：众包平台根据该智能合约相关信息，确定该智能合约有效。
S15：众包平台向任务接收终端发送该智能合约对应的密码破解任务。
以太坊在接收到众包平台发送的上述调用请求后，将智能合约的相关信息发送给众包平台，众包平台可根据该智能合约相关信息中参数“isActive”当前的值，来确定该智能合约是否有效，这里，假设参数“isActive”取值为1时表征智能合约有效，参数“isActive”取值为0时表征智能合约无效，并假设该智能合约中参数“isActive”当前的值为1，那么，众包平台可确定该智能合约有效，并向任务接收终端发送智能合约对应的密码破解任务执行，以便任务接收终端执行该密码破解任务。
S16：任务接收终端向众包平台发送破解结果。
S17：众包平台向以太坊转发破解结果。
任务接收终端接收到众包平台发送的密码破解任务之后，使用其可获得的计算资源对密码破解任务进行破解，其可获得的计算资源可以为任务接收终端自身所拥有的计算资源，也可以为其可获得的其他终端的计算资源。当任务接收终端完成密码破解任务的破解时，可将破解结果发送给众包平台，以便众包平台将该破解结果转发给以太坊。
S18：以太坊根据所述智能合约验证破解结果正确，且确定该破解结果为第一个验证正确的结果。
S19：以太坊根据所述智能合约向任务接收终端支付以太币。
以太坊根据所述智能合约对接收到的破解结果进行验证，若验证成功，以太坊还可验证该破解结果是否为针对其对应的密码破解任务的第一个验证成功 的结果，若是，以太坊将用于支付其对应的密码破解任务的50以太币支付给任务接收终端，即将该50以太币从该任务发起终端用户的以太币地址转到任务接收终端用户的以太币地址中，以完成支持。
若验证失败，如破解结果错误导致验证失败，或破解结果正确、但该结果不是针对其对应的密码破解任务的第一个验证成功的结果导致的验证失败，则智能合约可继续等待其他任务接收终端的破解结果。
所以，通过上述方法，在接收到任务发起终端发送的密码破解任务请求时，可以从以太坊调用智能合约构造函数，构造与密码破解任务对应的智能合约，并在任务接收终端实施密码破解任务后，由以太坊根据智能合约对其破解结果验证，保证了验证结果的准确性和公正性，解决了任务发起终端与任务接收终端之间就执行结果质量之间的信任问题，且以太坊可根据验证结果通过智能合约自动执行以太坊即报酬的分配，保证报酬能够顺利分配到符合成功完成任务的任务接收终端，所以，进一步解决了任务发起终端与任务接收终端方之间在执行密码破解任务过程中的信任问题，同时也不需要第三方介入实施仲裁，简化了密码破解任务执行的复杂度，进一步的，由于执行密码破解任务过程中结果公开且无法篡改，所以也抵御了伪造结果的非法操作。
进一步的，在密码破解任务被成功破解之后，由以太坊根据智能合约按照约定分配给任务接收终端，保证了任务接收终端获取对应报酬的权益，所以，能够吸引更多的任务接收终端投入更多的计算资源执行密码破解任务，所以，也提升了密码破解任务的执行效率和成功率，进而提高了密码破解任务对应的密码的安全评估质量。
