ScholarBank@NUS Repository. https://doi.org/10.1109/Metrisec.2011.17||Abstract:||Public Key Infrastructure (PKI) is a key infrastructure for secure communications and transactions on the Internet. We revisit the problem of timely certificate revocation and develop a performance analysis framework with more realistic assumptions of when certificates are revoked, a query model differentiating revoked and unrevoked certificates, and realistic cost factors. Our analysis is fine-grained and shows the impact of a revocation scheme on the computation, storage and bandwidth costs particularly on mobile devices as the verifiers. We apply our performance framework to analyze the following schemes: CRL, OCSP, CRS and CREV. Our analysis shows clearly the strengths and weaknesses of each scheme particularly for mobile lightweight verifiers under higher timeliness guarantees. © 2011 IEEE.||Source Title:||Proceedings - 2011 3rd International Workshop on Security Measurements and Metrics, Metrisec 2011||URI:||http://scholarbank.nus.edu.sg/handle/10635/41737||ISBN:||9780769546803||DOI:||10.1109/Metrisec.2011.17|
