终端和服务器之间的双向认证方法
摘要：
本发明涉及一种终端和服务器之间的双向认证方法。该方法包括该终端产生身份标识号和第一随机数，并发送给该服务器；该服务器验证该身份识别号是否存在于该服务器数据库中；该服务器根据该身份标识号、该第一随机数和服务器密钥产生一第一运算结果，该第一运算结果和一第二随机数传送到该终端；该终端根据该身份标识号、该第一随机数和该服务器密钥产生一第二运算结果，根据该第一、第二运算结果该终端对该服务器进行认证；该终端根据该第二随机数和终端密钥产生一第三运算结果，并将该第三运算结果发送到该服务器；该服务器根据该第二随机数和该终端密钥产生一第四运算结果，根据该第三、第四运算结果该服务器对该终端进行认证。
摘要（英）：

The invention relates to a mutual authentication method between a terminal and a server. The method comprises that: the terminal generates an identity number and a first random number and sends the identity number and the first random number to the server; the server verifies whether the identity number exists in a database of the server; the server generates a first operation result according tothe identity number, the first random number and a server secret key, and the first operation result and a second random number are transmitted to the terminal; the terminal generates a second operation result according to the identity number, the first random number and the server secret key and carries out authentication on the server according to the first and second operation results; the terminal generates a third operation result according to the second random number and a terminal secret key and sends the third operation result to the server; and the server generates a fourth operationresult according to the second random number and the terminal secret key and carries out authentication on the terminal according to the third and fourth operation results.
