Wireless '96 Design of Secure End-to-End Protocols for Mobile Systems

Use of mobile personal computers in open net-worked environment is revolutionalising the way we use computers. Mobile networked computing is raising some important information security and privacy issues. This paper is concerned with the design of authentication protocols for a mobile networked computing environment. We propose mobile user authentication protocols in intra and inter domain situations using symmetric key based cryptosystems. The paper then extends these protocols to an end-to-end situation, thereby allowing two mobile users to have secure conversations. The protocols provide varying degrees of anonymity of the communicating users to other system users.
