Revocatoin: Options and challenges

Abstract

Public keys can be trusted if they are digitally signed by a trusted third party. This trust is most commonly conveyed by use of a digital certificate. However, having once established trust in a public key, means must exist to terminate that trust should circumstances dictate. The most common means to do so is through revocation of the corresponding digital certificate. This paper identifies and discusses options that may be considered by those undertaking to address the revocation of digital certificates.
