Online Certificate Status Checking in Financial Transactions:  The Case for Re-issuance

Barbara L. Fox and Brian A. LaMacchia

 


Abstract

High-value financial transactions underwrite the need for a relying party to check the status of a digital certificate in real time. In this paper, we propose a simple mechanism for online certificate status checking that is particularly well-suited to the closed public key infrastructures that characterize financial networks. We further identify a dangerous trend towards maintaining the lifetime of a certificate for non-technical reasons and, as a by-product, create overly-complex protocols and data structures.
