    • A method and device for authenticating a MS has an R-UIM by using CAVE Algorithm are provided. The hardware structure of the device includes a cdma2000/HRPD dual-mode chip, a User Identity Module supporting the CAVE algorithm. The dual-mode terminal forms the NAI value with the domain name stored in a memory of the dual-mode terminal in advance by the IMSI. The dual-mode terminal extracts a RAND that is necessary for the calculation of an authentication parameter1 from the Random values included in a Chap Challenge message, instructs the R-UIM card to use the CAVE algorithm to calculate the authentication parameter1 with the RAND and an existing SSD_A in the R-UIM card, and bears the authentication parameter1 by the Result domain of a Chap Response message. With the present invention, the wastes caused by the replacement of R-UIM cards can be avoided.
    • 用于认证MS的方法和设备具有使用CAVE算法的R-UIM。 该设备的硬件结构包括cdma2000 / HRPD双模芯片,支持CAVE算法的用户识别模块。 双模终端由IMSI预先形成存储在双模终端的存储器中的域名的NAI值。 双模终端从Chap Challenge消息中包含的Random值提取认证参数1计算所需的RAND,指示R-UIM卡使用CAVE算法计算出RAND的认证参数1, 在R-UIM卡中存在SSD_A,并通过Chap响应消息的Result域承载认证参数1。 利用本发明,可以避免由更换R-UIM卡引起的废物。

    • A method for Access Authentication in the High Rate Packet Data Network is proposed in the present invention comprising steps of the AN-AAA receiving the Radius Access Request message sent from the HRPD AN; the AN-AAA judging whether a terminal is a roaming one according to the Network Access ID and transmits the roaming terminal's authentication information to the terminal's home nerwork. If said terminal is a local one, the AN-AAA judges the type of the terminal according to the NAI value. If said terminal is a single-mode one, the AN-AAA works out the Result2 with the MD5 algorithm. if said terminal is in dual-mode, the AN-AAA calculates the Result2 with the CAVE algorithm to compare the Result1 with the Result2.
    • 本发明提出了一种高速率分组数据网络中的接入认证方法,包括AN-AAA接收HRPD AN发送的半径接入请求消息的步骤; AN-AAA根据网络接入ID判断终端是否为漫游终端,并将漫游终端的认证信息发送到终端的家庭故障。 如果所述终端是本地终端,则AN-AAA根据NAI值来判断终端的类型。 如果所述终端是单模,则AN-AAA使用MD5算法来计算Result2。 如果所述终端处于双模式,则AN-AAA使用CAVE算法计算Result2,以将Result1与Result2进行比较。
