Security Analysis of Concast and Anycast Digital Signature
In the above paper a conception has been proposed which is a variant of the ElGamal-type digital signature. It considers the problem of authentication in the concast and anycast communication model. This paper proposed an improvement of concast scheme and also given a forgery attack on the anycast scheme. The authors state signature scenario scheme as follows.
