Abstract

Abstract

En 中文
In this paper we introduce a new authentication scheme to achieve individual authentication in group communications. The scheme is particularly efficient and suitable for applications where users require to transmit stream of data of undefined length through noisy channels. Our scheme is in fact, robust against loss of packets during the transmission. We present the scheme called chained stream authentication (CSA) and then we prove that the scheme is conditionally secure. We then describe two variations of CSA, one interactive to use when multicast is available and a timed version suitable for broadcast communications. We conclude by describing our implementation of the timed version that is integrated and fully compatible with RAT.
