A Construction of Multi-receiver Authentication Codes with Dynamic Sender from Linear Codes

Multi-receiver authentication codes with dynamic sender (DMRA-codes) are extensions of traditional group communication system in which any member of a group can broadcast an authenticated message such that all other group members can individually verify its authenticity, and some malicious participants of group can not successfully impersonate the potential sender, or substitute a transmitted message. In this paper, a construction of DMRA-code will be given using linear code and its unconditional security is also guaranteed.
