Abstract

The Public Key Certificate (PKC) is an important way to support the secure global WEB applications. The revocation of the PKC, however, remains as one of the most costly problems in the certificate management. In this paper, a new public key certificate revocation scheme based on one-way hash chain is proposed. Specifically, no centralized authority holds responsibility to collect and publish certificate status information. Instead, the individual user takes charge of his own certificate status by periodically releasing an updated secure hash value. The paper concludes with an informal examination of the security, efficiency and scalability of this scheme.
