Trusted Principal-Hosted Certificate Revocation

Abstract : Public Key Infrastructure is a key infrastructure for secure and trusted communication on the Internet. This paper revisits the problem of providing timely certificate revocation focusing on the needs of mobile devices. We survey existing schemes then present a new approach where the principal’s server functions as the directory for its own revocation information. We evaluate the properties and trust requirements in this approach, and propose two new schemes, CREV-I and CREV-II, which meet the security requirements and performance goals. Evaluation of CREV shows it is more lightweight on the verifier and more scalable at the CA and the principals while providing near real-time revocation.
