METHOD FOR PERFORMING ENCRYPTED COMMUNICATION BY OBTAINING AUTHENTICATION, AUTHENTICATION SYSTEM AND METHOD

摘要

PROBLEM TO BE SOLVED: To improve security in a system utilizing Web services. SOLUTION: An AP 11 of a user terminal transmits an authentication request to an authentication server 2. When the authentication server 2 authenticates the AP 11, a session key used for encryption and decryption is transmitted to the user terminal 1. When a job server 3 accepts from the user terminal 1 a sign-on request to a service component 32, an authentication request of the service component 32 is transmitted to the authentication server 2. When the authentication server 2 authenticates the service component 32, the same session key is transmitted to the job server 3. The AP 11 and the service component 32 then use the session key, respectively to perform encrypted communication with each other. COPYRIGHT: (C)2007,JPO&INPIT
