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
