The Ad Hoc Networks in Security Sensitive Applications Using Tam A Tiered Authentication of Multicast Protocol

Abstract

TAM(Tiered Authentication of Multicast Protocol), which pursues a two tired hierarchical strategy combining both time and secret-information asymmetry in order to achieve scalability and resource efficiency. The performance of TAM has been analysed mathematically and through simulation, confirming its effectiveness. The simulation and analytical results demonstrate the performance advantage of TAM in terms of bandwidth overhead and delivery delay. A new Tiered Authentication scheme for Multicast traffic (TAM) for large scale dense ad-hoc networks. TAM combines the advantages of the time asymmetry and the secret information asymmetry paradigms and exploits network clustering to reduce overhead and ensure scalability. Multicast traffic within a cluster employs a one-way hash function chain in order to authenticate the message source. newline
