Layered Multicast Data Origin Authentication and Non-repudiation over Lossy Networks

Abstract

Security and QoS are two main issues for a successful wide deployment of multicast services. For instance, in a multicast streaming application, a receiver would require a data origin authentication service as well as a quality adaptation technique for the received stream. Signature propagation and layered multicast are efficient solutions satisfying these two requirements. In this paper we investigate the use of signature propagation to ensure data origin authentication service. We, then, propose a set of novel data origin authentication techniques for layered media-streaming video. In addition to data origin authentication, the proposed techniques offer continuous non-repudiation of the origin and data integrity. These techniques take advantage of the preestablished layered structure of the encoded video data to reduce the overhead and improve the overall verification in lossy network environments. We evaluate the performance of the proposed techniques through extensive simulations using NS2 simulator.

Survey on multicast data origin authentication

“…It is assumed that the packets in the highest priority class are spaced evenly throughout the block so that two consecutive packets of the highest priority class are located exactly r packets apart. To reduce the communication overhead of amortization schemes, Park et al proposed SAIDA [20] using Erasure Codes to achieve this goal, but its computation overhead is higher than other schemes based on hashing amortization [1,2,3,[5][6][7][8]11,13,14,21]. …”

LMCM: Layered Multiple Chaining Model for Authenticating Multicast Streams

“…In the random chaining, target packets that will carry a hash of the current packet are selected randomly. This approach complies with the random packet loss pattern [2,3,4,5,7]. In order to take advantage of both approaches, …”
