Abstract

In this article, we propose a new public key authentication scheme for cryptosystems with a trusty server. The scheme is based on discrete logarithms. In the scheme, the certificate of the public key is a combination of user's password and private key. The scheme not only resolve the problems appeared but also is secure for the others public-key authentication.
