摘要： A method and an apparatus for secure registration for a multicast-broadcast-multimedia system (MBMS) are disclosed. A random number is generated by a broadcast-multicast-service center (BM-SC) and broadcast to user equipment in the coverage area of a radio access network (RAN). A memory module or smart card (UICC) in the user equipment generates a radio access network key (RAK) which is a function of the random number and a key selected from the group consisting of a public land mobile network key (PK) and a broadcast access key (BAK), and then generates a temporary registration key (RGK) as a function of the RAK, a service identification number and a user identification number, for example, P-TMSI, which may be extracted by the RAN to authenticate the registration as legitimate.

摘要： Methods and apparatus for protecting user privacy in a shared key system. According to one aspect, a user generates a derived identity based on a key and a session variable, and sends the derived identity to an application. In one embodiment, a key server may be used to receive the derived identity from the application, and return a sub-key to the application to use for encrypting communications with the user.
摘要翻译：在共享密钥系统中保护用户隐私的方法和装置。根据一个方面，用户基于密钥和会话变量生成导出的身份，并且将所导出的身份发送到应用。在一个实施例中，密钥服务器可以用于从应用程序接收导出的身份，并将子密钥返回到应用程序以用于加密与用户的通信。

摘要： A method of requesting and issuing a certificate from certification authority for use by an initiating correspondent with a registration authority is provided. The initiating correspondent makes a request for a certificate to the registration authority, and the registration authority sends the request to a certificate authority, which issues the certificate to the registration authority. The certificate is stored at a location in a directory and this location is associated with a pointer such as uniform resource locator (URL) that is derived from information contained in the certificate request. The initiating correspondent computes the location using the same information and forwards it to other corespondents. The other correspondents can then locate the certificate to authenticate the public key of the initiating correspondent.
摘要翻译：提供了一种从认证机构请求和颁发证书以供初始记者与注册机构使用的方法。起诉记者向登记机关发出证书请求，登记机关向认证机关发送请求，认证机构向认证机构发放证书。证书存储在目录中的位置，并且该位置与诸如从证书请求中包含的信息派生的统一资源定位符（URL）的指针相关联。启动通讯员使用相同的信息计算位置，并将其转发给其他通讯员。其他通讯员然后可以定位证书来验证初始通讯员的公钥。
