    • A data file decryption method, a decryption device and a data broadcasting system are disclosed, which are applied to a data broadcasting service. Among them, the data file decryption method includes the steps of: receiving the file delivery information which includes a data file identification and a key file identification corresponding to the data file; receiving the corresponding data file and key file according to the data file identification and the key file identification; and decrypting the data file according to the key file. According to the data file decryption method, decryption device and the data broadcasting system of the present invention, by setting the data file identification and the corresponding key file identification in the file delivery information and receiving the corresponding file according to the data file identification and the key file identification, the resource dissipation due to a large quantity of useless information received at a terminal is avoided, and the file to be received can be quickly located by the terminal, so that the time delay due to the decryption of a data file is avoided, and the service experience for users is improved.
    • 公开了一种应用于数据广播服务的数据文件解密方法,解密装置和数据广播系统。 其中,数据文件解密方法包括以下步骤:接收包含与数据文件相对应的数据文件标识和密钥文件识别的文件传送信息; 根据数据文件识别和密钥文件识别接收相应的数据文件和密钥文件; 并根据密钥文件对数据文件进行解密。 根据本发明的数据文件解密方法,解密装置和数据广播系统,通过将数据文件识别和对应的密钥文件识别设置在文件传递信息中,并根据数据文件标识接收对应的文件, 关键文件识别,避免了在终端接收到的大量无用信息引起的资源耗散,并且可以由终端快速定位待接收的文件,使得由于数据文件的解密而引起的时间延迟是 避免了,用户的服务体验得到改善。

    • An authentication system, method and device are provided in the present application. The authentication system includes an Application Server (AS) for providing non Internet protocol Multimedia Subsystem (IMS) service, an authentication gateway and an IMS terminal. The AS forwards a connection request message sent by the IMS terminal to said authentication gateway, the authentication gateway sends a obtained first random number to said IMS terminal through the AS, the IMS terminal generates a first Response (RES) value according to the first random number and sends the generated first RES value to the authentication gateway through the AS, and if the received first response value and an obtained Expected Response (XRES) value is found coincident after being compared by the authentication gateway, the authentication gateway determines that the authentication to the IMS terminal is passed, and indicates the AS to provide non IMS service for the IMS terminal. By using the technical solutions of the present application, solved is the problem existed in prior art that non IMS AS needs to authenticate each of IMS terminals respectively for obtaining non IMS service and thus reducing the service processing efficiency of the AS.
    • 本申请中提供了认证系统,方法和设备。 认证系统包括用于提供非互联网协议多媒体子系统(IMS)服务的应用服务器(AS),认证网关和IMS终端。 AS将IMS终端发送的连接请求消息转发给认证网关,认证网关通过AS向IMS终端发送获取的第一个随机数,IMS终端根据第一个随机数生成第一个响应(RES)值 并通过AS将生成的第一RES值发送给认证网关,如果在认证网关进行比较后发现接收到的第一响应值和获得的预期响应(XRES)值一致,则认证网关确定认证 通过IMS终端,并指示AS为IMS终端提供非IMS业务。 通过使用本申请的技术方案,解决了现有技术中存在的问题,即非IMS AS需要分别对每个IMS终端进行认证,以获得非IMS业务,从而降低AS的业务处理效率。
