A taxonomy of multicast data origin authentication: Issues and solutions

“…Several schemes have been proposed 978-1-4244-4652-0/09/$25.00 c 2009 IEEE to address this problem in different settings [1]. However, no rigorous analysis and quantitative comparison of the different schemes have been done in the literature, to the best of our knowledge.…”

The problem of multimedia stream authentication has received significant attention by previous works and various solutions have been proposed. These solutions, however, have not been rigorously analyzed and contrasted to each other, and thus their relative suitability for different streaming environments is not clear. In this paper, we conduct comprehensive analysis and comparison among the main authentication schemes proposed in the literature. To perform this analysis, we propose five performance metrics: computation cost, communication overhead, receiver buffer size, delay, and tolerance to packet losses. We derive analytic formulas for these metrics for all schemes, and we numerically analyze these formulas. In addition, we implement all schemes in a simulator to study their performance in different environments. Our detailed analysis reveals the merits and shortcomings of each scheme and provides guidelines on choosing the most appropriate scheme for a given application. Our analysis also helps in designing new authentication schemes and/or improving existing ones.

“…In contrast, multicast data origin authentication is more complicated because the group key which is known by all group members cannot be used to identify a specific sender. We distinguish between two levels of multicast data origin authentication [6]:…”
