Using classical groups to construct authentication codes
LI Dian-long · Journal of Computer Applications · 2010
To design a simple and practical authentication scheme is one of the important issues in the authentication codes research.Applying partition of positive integers and Anzahl theorem of subgroups of classical groups,a class of authentication codes was obtained and all parameters of this scheme were computed.Simultaneously,supposing that the secret key was chosen according to the uniform probability distribution,security analysis of the scheme was given.The construction increased the number of the source state dramatically,which indicates that this code has better traits than some other codes obtained by matrices method before.
