Abstract

本发明的目的在于提供一种方法，该方法通过专用于该对用户单元/安全组件的匹配密钥，来确保安全组件和用户单元之间交换数据的加密，且同时允许该安全组件与其他用户单元配对。依照本发明，此目的通过包含下述步骤的方法来实现：由用户单元检测所连接的安全组件与其是否配对，如果匹配，则使用专用于该对用户单元/安全组件的唯一配对密钥来加密交换数据，如果不匹配，则请求操作中心授权与该安全组件配对，请求附有该用户单元以及该安全组件的标识符，由操作中心来验证该匹配请求的符合度，并且将结果传送到用户单元，如果给予授权，则建立属于该对用户单元/安全组件的配对密钥，以用来加密交换数据。

Description

匹配控制方法
本发明涉及一种用户单元和安全组件之间安全信息传送的管理方法，特别是在该安全组件与多个用户单元相互作用期间。
这些用户单元与一个或多个提供产品或服务的网络相连。
这些产品或服务需进行有条件的访问，使用这些产品须以任何形式进行支付，例如通过定购或特殊购买。
这些用户单元能以多种形式出现，例如，收费电视解码器、计算机，甚至是移动电话、掌上型电脑、PDA、收音机、电视机、多媒体工作站、自动柜员机。
对于产品或服务，我们理解不仅包括电影、体育消息广播、音乐、计算机程序、游戏、股票市场或新闻信息，而且包括诸如访问及使用网络，识别或电子支付的服务。该产品或服务可以在用户能够连接到其上，并且为安全起见而使用了加密装置的网络上获得。
为了管理使用这些产品或服务的授权，用户单元还包括有设置在安全组件中的安全装置。
该安全组件一般以智能卡、***或微处理器，甚至是包括加密处理器(USIM，WIM)的SIM卡的形式出现。通过使用存储在加密处理器的存储器中的密钥的解密操作，该卡允许提供必要的信息，以便授权使用该产品，而这被认为是不可违反的。
该安全组件负责与用户单元交换机密消息，例如，当在收费电视领域中传送产品的解密密钥时，该密钥在安全组件中被解密，并传送到用户单元以处理数据。
这就是为了防止与这些数据干扰，对安全组件和用户单元之间的通讯装置，由被称为配对密钥的专用于这两个元件的密钥进行解密的原因。这种结构在PCT/IB99/00821的申请中描述过，其中专用密钥最初在解密器中，而后在初始化阶段的期间被装入该安全组件。一旦安全组件与解码器相匹配，则此组件就不能在其他任何单元中运行。
此解决方案显现出的第一个不便之处，是其阻止了该安全组件在另外的解密器中任意使用，即使该解码器属于同一用户。此方法的另一个不便之处，是其不能防止使用克隆卡(cloned card)，该克隆卡在任一解密器中首次使用后，其就能与此解码器配对。
本发明的目的在于提供一种方法，该方法用于确保在安全组件和用户单元之间交换的数据的解密，同时消除了上述的不便之处。
此目的通过安全组件和用户单元之间的配对管理方法来实现，后者具有双向通讯装置，该装置具有操作中心，其特征在于该方法包括：
-由用户单元检测所连接的安全组件与其是否配对，
-如果匹配，则使用专用于该对用户单元/安全组件的唯一配对密钥来加密交换数据，
-如果不匹配，则请求操作中心授权与该安全组件配对，请求附有用户单元以及安全组件的标识符，
-由操作中心来验证该配对请求的符合度，并且将结果传送到用户单元，
-如果给予授权，则建立属于该对用户单元/安全组件的配对密钥，以用来加密交换数据。
由此，该匹配管理以一种动态的方式来执行，并且不再是用户单元中安全组件连接的结果。其通过操作中心来管理，该操作中心确定是接受还是拒绝此配对。这就是为什么要将该请求，附加上这两个元件的标识符、诸如它们的序列号的数据的原因。该请求能够附加关于该单元位置、由其他装置所获得的数据，例如其网络上该单元的呼叫号码或者地址。
对匹配密钥，我们理解为对称或非对称密钥，例如，公共或私有密钥。在后面的情况下，将提出下列三种情况：
-每个部件都包括两个公共和私有密钥。向其他部件的通讯，由公共密钥进行加密，然后由私有密钥进行解密。
-每个部件都包含公共或私有密钥中的一个。在一种倾向中，数据将由公共密钥进行加密，然后由私有密钥进行解密，而在另一种倾向中，数据由私有密钥进行加密，然后由公共密钥进行解密。
-每个部件都包含其他部件的公共密钥以及其自身的私有密钥。数据由其他部件的公共密钥进行加密，而由其自身拥有的私有密钥进行解密。
应该注意到，安全组件能够与多个用户单元进行配对。其存储器具有用于存储一组匹配密钥的分区，每个密钥都与用户单元的识别号相关联。
由此，在用户单元中的这种组件的每个连接过程中，初始协议包括相互识别以及使用专用于该对用户单元/安全组件的密钥(或多个密钥)。
依照一个实施例，用户单元同样能够具有匹配密钥的分区，且由此使得该用户单元能够与多个安全组件配对。
该单一的密钥能够通过多种方法来产生。其能够由该操作中心产生，并以加密的形式，通过匹配授权的情况下传送，以加密的形式被获知。根据公知的程序，使用根据对话密钥而建立的加密，将该密钥传送到安全组件。
获得此专用密钥的另一种方法是在用户单元，或安全组件，或者部分在这些元件中的每一个产生它，且合并后由此形成该密钥。
在本发明方法的一个实施例中，对操作中心的请求不仅附加了该对用户单元/安全组件的识别数据，而且附加了包含在配对存储器分区中的数据，该存储器分区包括所有先前的配对。
操作中心于是核对该安全组件已经与它已经授权用户的用户单元，并按照请求的顺序配对。
由此，如果安全组件已经被克隆，当此克隆组件需要与用户单元配对时，传送到操作中心、涉及先前匹配的数据，将不同于那些原始组件。为此，该操作中心具有用于识别克隆组件的装置。
首次操作时，操作中心部将接受此克隆卡与新用户单元B的配对。如果已经大规模地使用真实卡的克隆，那么下一张克隆卡，该卡具有相同的用户标识符，请求与新的用户单元C进行配对，则操作中心部将无法找出先前与用户单元B进行匹配的任何痕迹。这种指示将能够检测到欺诈的企图，并且由此而发挥作用。此外，如果该真实卡的用户想在新的单元D上使用该卡，那么由此组件传送的配对数据，将不包含单元C的任何痕迹，且操作中心将拒绝此次配对，并甚至引起完全阻塞该安全组件。
