    Abstract: The advancement of public-key cryptography in
    recent years has offered strong background support for
    the invention of numerous new system applications vastly
    employed in electronic business as well as other fields. However,
    that does not change the fact that the one-and-only
    Internet still remains open and unprotected. Therefore, for
    the sake of information security, confirming the legality of an entity’s public key is always critical. Typically, a key authentication scheme needs one or more authorities to authenticate keys. To make a difference, in this study, we have developed a new key authentication scheme using generalized discrete logarithm problem and integer factorization problem for cryptosystems. Although the new scheme works pretty much the same way as regular certificate-based techniques,it differs in that it needs no authority. Taking the password/secret key pair as the certificate of public key for an entity, the new key authentication technique is very simple
    but profoundly secure.
