Abstract:

In a group communication system,the basic authentication systems refer to the multi-receiver authentication codes with dynamic senders (DMRA-code). At present,many scholars have a lot of researches,in which the authentication of source state is restricted as only one. However,in the network communication,there are always scenarios in which multiple source states are required to be authenticated. Based on this problem,a multiple message authentication code with dynamic senders is constructed with symmetric polynomials. In addition,the probabilities of possible attacks are computed to ensure the scheme security.

Key words: authentication code, multiple message, dynamic, plynomial
