ABSTRACT
This paper reports on an investigation into several differing certificate validation techniques. It compares their mechanisms and, more importantly, their performance. An analysis is presented showing the largest number of validator clients that each validation method can support. This is done in each of five differing scenarios, scenarios that are encountered in a web environment. The affect of caching validation information is also examined. Finally, a new, hybrid method for disseminating certificate validity information is presented and recommendations are made for which method use in varying circumstances.
