    • Apparatus and method for generating a traffic encryption key includes generating a traffic encryption key for encrypting data transmitted as part of a service, the traffic encryption key having a validity equal to a traffic encryption key validity time period; checking whether a period for the service is longer than the traffic encryption key validity time period; and if the period of the service is longer than the traffic encryption key validity time period, ascertaining a residual period which indicates by what period the service is longer than the traffic encryption key validity time period of the traffic encryption key; generating a residual traffic encryption key which is used for encrypting data transmitted as part of a service; ascertaining a residual traffic encryption key validity time period which indicates for how long the residual traffic encryption key is valid; and associating the residual traffic encryption key validity time period with the residual traffic encryption key.
    • 用于生成流量加密密钥的装置和方法包括:生成用于加密作为服务的一部分发送的数据的流量加密密钥,所述流量加密密钥具有等于流量加密密钥有效期的有效性; 检查服务的周期是否长于流量加密密钥有效期; 并且如果所述服务的周期长于所述流量加密密钥有效期间,则确定指示所述服务比所述流量加密密钥的流量加密密钥有效期间长的时间段的剩余期间; 生成用于加密作为服务的一部分发送的数据的剩余业务加密密钥; 确定剩余业务加密密钥有效期,指示剩余业务加密密钥有效多久; 并将剩余业务加密密钥有效期与剩余业务加密密钥相关联。

    • Server of a communication system having a broadcast communication network, a communication service server and a storage device, the server providing a plurality of media streams which can be transmitted in a service area of the broadcast communication network by the broadcast communication network. The server includes a determination device that interrogates parameter values from a storage device for each client situated in the service area, and receives data which are transmitted by the broadcast communication network, wherein the parameter values are used to determine which of the media streams are intended to be communicated to the respective client, and determines based on the parameter values which of the media streams are intended to be transmitted by the broadcast communication network in the service area. The server also includes a controller that controls the broadcast communication network such that the network transmits the media streams which are intended to be transmitted.
