متن کاملPassword Protected Smart Card and Memory Stick Authentication against Off-Line Dictionary Attacks
We study the security requirements for remote authentication with password protected smart card. In recent years, several protocols for password-based authenticated key exchange have been proposed. These protocols are used for the protection of password based authentication between a client and a remote server. In this paper, we will focus on the password based authentication between a smart ca...
