New constructions of equitable authentication codes with arbitration
Shucui Xie · Journal of Shaanxi Normal University · 2001
A new method to construct equitable authentication codes with arbitration is given through designing a kind of special functions. A class of equitable authentication codes with arbitration is constructed. The messages, the transmitter′s encoding rules, and the receiver′s decoding rules in the construction are divided into several parts respectively. Then a special function operates on them. The arbiter chooses the encoding rules in some way and distributes the rules to the transmitter and the receiver. The method to construct authentication codes has great agility, the number of source states can be arbitrarily large, and the construction is of more efficiency. The security can be designed at any level according to different requirement. The resulted codes can meet the optimal code-bound.
