| Abstract: | In the past, several key agreement protocols are proposed on password based
mechanism. These protocols are vulnerable to dictionary attacks. Storing plain
text version of password on server is not secure always. In this paper we utilize
the service of a trusted third party, i.e., the Key Distribution server (KDS) for key
agreement between the hosts. Now-a-days in large working environments two
party key agreement protocols are being rarely used. In this proposed scheme,
instead of storing plain text version of password we store one way hash of the
password at the server. Every host and server agree upon family of commutative
one-way hash functions, using which host authentication is done when a host
applies for session key with KDS. Host establishes one time key with server
using which server authentication is done. Due to this man-in-the middle attacks
are defeated. The proposed protocol is based on Diffie-Hellman key exchange
protocol. |
