20110276804 | SERVER AUTHENTICATION METHOD AND CLIENT TERMINAL - A server authentication method is provided. In the method, a client receives a public key of an evaluated server during establishment of a secure communication path with the evaluated server. The client terminal transmits a first ID to the evaluated server. The client terminal receives a second ID and a first random number from the evaluated server. The client terminal determines that the evaluated server is valid when the received first random number corresponds to the transmitted first ID and a public key stored in a public key management unit configured to manage the public key in advance is identical to the received public key. The client terminal transmits a second random number corresponding to the second ID to the evaluated server when the evaluated server is determined to be valid. | 11-10-2011 |
