用于解密加密服务的系统和方法
摘要：
本发明涉及由至少包括第一条件访问系统和第二条件访问系统的系统中的用户的用户终端解密加密服务的系统和方法。第一和第二条件访问系统彼此连接，至少第二条件访问系统连接到用户终端。第一条件访问系统通过第一标识符与用户终端中的第一安全客户端关联。第二条件访问系统通过第二标识符与用户终端中的第二安全客户端关联。由第一条件访问系统生成至少一个第一授权管理消息。此第一授权管理消息携带第一标识符和用户终端的用户对用户终端的用户已经预订的加密服务进行解密的授权。向第二条件访问系统传输第一授权管理消息。第二消息是在第二条件访问系统上生成的，并携带第二标识符。第一授权管理消息被封装在第二消息中，然后传输到用于解密加密服务的用户终端。
摘要（英）：

The invention relates to a system and a method of enabling decryption of an encrypted service by a user terminal of a subscriber in a system comprising at least a first conditional access system and a second conditional access system is proposed. The first and second conditional access system are connected to each other and at least the second conditional access system is connected to the user terminal. The first conditional access system is associated with a first security client in the user terminal by means of a first identifier (e.g. an identifier of an operator of the first conditional access system). The second conditional access system is associated with a second security client in the user terminal by means of a second identifier (e.g. an identifier of an operator of the second conditional access system). At least one first entitlement management message is generated by the first conditional access system. This first entitlement management message carries the first identifier and an entitlement for the subscriber of the user terminal for decrypting the encrypted services to which the user of the user terminal has subscribed. The first entitlement management message is transmitted to the second conditional access system. A second message is generated at the second conditional access system and carries the second identifier. The first entitlement management message is encapsulated in the second message and then transmitted to the user terminal for enabling decryption of the encrypted service.
