Abstract

Keystroke dynamics is an intelligent data processing technique of analyzing the user's habitual typing patterns to identify him. Keystroke dynamics combined with password authentication has been widely used as a means to enhance user authentication system. However, the user authentication system's security does not rely solely on the keystroke dynamics. To guarantee a high level of security, more secure password authentication is needed. The design and development of a secure password authentication protocol for keystroke dynamics is discussed in this paper. We propose a new efficient password authentication protocol that is secure against all types of attacks considered in the paper. We also show that our two-party protocol is extended to a three-party protocol, where each user only shares a password with a trusted server. As a result, our protocols with keystroke dynamics can provide a secure and intelligent means of authentication and access control of computer users.
