| Abstract: | This paper firstly point out the limitation of strong equivalence of 1] in analyzing the security relation between two signature schemes,and extend its idea security strong equivalence Then by use of the method of transform each other,we proof that ElGamal type signature scheme is security strong equivalence with corresponding MR(P) type scheme So the problem left in 2] is resolved |
