    • A method generates an authentication key to be used in an authentication algorithm at position at which a mobile station's subscriber is located. First, when there is a request to create the authentication key by a customer service center (CSC), at an authentication center module (ACM), a first type of parameters are issued and transmitted to a mobile station (MS). At the MS, a reference key to be used in creating the authentication key is then obtained on the basis of the first type of parameters to send the reference key to the ACM. A second type of parameter is derived by using the first type of parameters when the reference key is received from the MS and then transmitted to the MS at the ACM. At the MS, the authentication key is generated by using the first type of parameters, the second type of parameter and the reference key and a key generation complete message is transferred to the ACM. In response to the key generation complete message from the MS, at the ACM, the authentication key is generated by using the reference key from the MS, one of the first type of parameters and the second type of parameter and a key generation complete message is transferred to the CSC to allow the MS to be activated so that the MS's subscriber can use a communications service provided by a mobile communications system.
    • 一种方法产生将在移动台用户位于的认证算法中使用的认证密钥。 首先,当客户服务中心(CSC)有请求创建认证密钥时,在认证中心模块(ACM)处,发出第一类参数并发送给移动台(MS)。 然后在MS中,根据第一类参数获得用于创建认证密钥的参考密钥,以将参考密钥发送给ACM。 当从MS接收到参考密钥然后在ACM发送到MS时,通过使用第一类型的参数来导出第二类型的参数。 在MS中,通过使用第一类型的参数,第二类型的参数和参考密钥生成认证密钥,并且将密钥生成完成消息传送到ACM。 响应于来自MS的密钥生成完成消息,在ACM,通过使用来自MS的参考密钥生成认证密钥,第一类型的参数和第二类型的参数之一以及密钥生成完成消息是 转移到CSC以允许MS被激活,使得MS的用户可以使用由移动通信系统提供的通信服务。
