| Summary: | 碩士 === 世新大學 === 資訊管理學研究所(含碩專班) === 96 === For providing a secure distributed computer environment, efficient and flexible user authentication and key agreement is very important. For providing this security mechanism, we propose efficient and flexible password authenticated key agreement schemes using bilinear pairings. The major advantage for using bilinear pairings is the shorter key length with the same security. It can provide less storage space and computation time.
For providing the security mechanisms in different environments, we design security protocols in two-party and three party setting. The main merits in our proposed schemes include: (1) there does not need any password or verification table in the server; (2) users can choose or change his own password freely; (3) both of the server and a user can authenticate each other; (4) the user and the server can generate a session key; (5) it does not have a serious synchronization-clock problem; (6) even if the secret information stored in a smart card is compromised, it can prevent the offline dictionary attack; (7) it can prevent the server compromise in our three-party protocol.
