An Authentication and Security Protocol for Mobile Computing

The main contributions of this paper are to analyze an authentication and key distribution protocol for mobile computing proposed by Beller Chang and Yacobi in and reveal two problems associated with their protocol to propose a new authentication and key distribution protocol that utilizes a broadcast channel in a mobile network A particularly interesting feature of the new proposal is that it allows the authentication of a base station by a mobile user to be conducted at the background which yields a very compact protocol whose total number of moves of information between a mobile user and a base station is only
