Abstract
Protecting public keys against intruders is very important in public key cryptosystems. Most key authentication schemes require one or more authorities to authenticate keys. In this paper, we propose a new scheme for cryptosystems based on discrete logarithms. It is similar to the conventional certificate-based schemes, yet it requires no authorities. The certificate of the public key of a user is a combination of his password and private key. Our scheme is highly secure and the authentication process is very simple.
