T wo New Constructions of Multi-receiver Authentication Codes from Singular Pseudo- Symplectic Geometry over Finite Fields
You Gao, Li-Wei Chang · WSEAS Transactions on Mathematics archive · 2012
In this paper, two new constructions of multi-receiver authentication codes using singular pseudosymplectic geometry on finite fields are described. Under the assumption that the encoding rules of the transmitter and the receiver are chosen according to a uniform probability distribution, the parameters and the probabilities of success for different types of deceptions are computed by the method of matrix and combinatorial enumeration.
