Evaluation of revocation systems with a Java test-bed

Public key cryptography is widely used to provide different security services. The PKI is the infrastructure that supports the public key cryptography and the revocation of certificates implies one of its major costs. Java test-bed has been developed for certificate revocation by J.L. Munoz and J. Forne (2003). The goal of this paper is to evaluate the most used revocation systems using this test-bed. In this sense, some results in terms of downlink bandwidth and processing capacity requirements are shown for CRL, OCSP and ADMHT.
