INTRODUCTION Wireless ad hoc networks have emerged to support applications‚ in which it is required/desired to have wireless variety of devices without relying on communications among a any infrastructure or central management. In ad hoc networks‚ wireless devices‚ simply called nodes‚ have limited transmission range. Therefore‚ each node can directly communicate with only those within its transmission range (i.e.‚ its neighbours) and requires other nodes to act as routers in

Cryptographic Authentication for Real-Time Network Protocols1‚2 David L. Mills3 Abstract This paper describes a new security model and authentication scheme for distributed‚ real-time network protocols used in time synchronization and event scheduling applications. It outlines the design requirements of these protocols and why these requirements cannot be met using conventional cryptography and algorithms. It proposes a new design called autokey‚ which uses a combination of public-key cryptography
