Research output: Contribution to journalArticlepeer-review


Previously, Desmedt and Seberry developed a practical proven secure authentication scheme with arbitration. Their scheme, however, only provides an environment for a single sender. Nevertheless, in real applications, many senders may collaboratively send a message to the receiver and convince the receiver that the message is actually transmitted by them. In this paper, we present an efficient scheme which (a) is unconditionally secure against denial by the senders having sent a message and (b) reduces the size of evidence for the authentic message and the number of enciphering keys to be held by the senders in a multi-senders environment.
