Stream Authentication Using Trapdoor Hash Function

Dodla Padmaja | P. Srilatha ^[3]

Abstract: Web based services engage distribution of contents like digital audio, video, games, software, stock quotes, Streaming presentations and live news feeds throughout distributed networking technologies, like Content Distribution Networks (CDNs), multicast networks, and peer-to-peer networks. We guard delay sensitive streams against malicious attacks, auditing mechanisms and security mechanisms need to be designed to efficiently process long sequence of bits. We have proposed a novel signature amortization technique based on trapdoor hash functions for authenticating each and every individual data blocks in the stream. Our technique affords for each and every intermediate blocks in the stream we want to stay away from the transmission loss and we will afford constant memory requirements for sender as well as receiver and we want to authenticate and verify the stream to keep away from unauthenticated user and to avoid malicious content.
