In this paper, we hope to combine discrete logarithm with factorization, that strengthen the security of multi-proxy.　Both of discrete logarithm and factorization are the hard problem of computational complexity. In execution of multi-proxy signature, we have to think over the problem of proxy change, for example quit job, sickness, or death. Then, in the paper, we hope to improve multi-proxy signature scheme for the problem of proxyies append and delete by Rabin’s scheme.
