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

common used topologies in networking are: bus‚ star‚ ring‚ mesh‚ tree‚ and hybrid. The three major topologies that I will be discussing further in detail are: bus‚ star‚ and ring topology. Bus topology is probably considered the easiest of the network topologies. In a bus topology‚ the devices are connected to a central cable called the bus. The bus cable carries the transmitted message along the cable. When the message arrives at each workstation‚ the computer checks the destination address contained
