Authentication of Online Digitized Content Using Trapdoor Hash Function Method

Abstract

Web based services involve distribution of content like digital audio, video, software, games, stock quotes, streaming presentations, and live news feeds through distributed networking technologies, like Content Distribution Networks (CDN’s), multicast networks, and peer-to-peer networks. We protect delay sensitive streams against malicious attacks, security mechanisms and auditing mechanisms need to be designed to efficiently process long sequence of bits. We propose a novel signature amortization technique based on trapdoor hash functions for authenticating each and every individual data blocks in the stream. Our technique provides for each and every intermediate blocks in the stream we want to avoid the transmission loss and we will provide constant memory requirements for sender as well as receiver and we want to authenticate and verify the stream to avoid unauthenticated user and to avoid malicious content.
