Abstract

We study the verification of data integrity during peer-to-peer video streaming sessions. Challenges include the timing constraint of streaming, as well as the untrustworthiness of peers. We show the inadequacy of existing authentication protocols and propose a more efficient protocol which utilizes message digest and probabilistic verification. We then propose One Time Digest Protocol (OTDP) and Tree-based Forward Digest Protocol (TFDP) to further reduce the communication overhead. Finally, a comprehensive comparison is presented comparing the performance of existing protocols and our protocols, with respect to overhead, security assurance level, and packet loss tolerance.
