INCREASING THE LEVEL OF SECURITY OF THE PROTOCOL GROUP DIGITAL SIGNATURE BASED ON THE MASKING MECHANISM OF PUBLIC KEYS

First we consider the problem of raising the level of security protocols, group signature based on the masking mechanism of public keys of signers and a suggestion for solution of practical interest. Developed a Protocol based on computational difficulty of simultaneously solving the problem of factorization and discrete logarithm problem for a Prime modulus.
