Abstract
The present invention is directed toward efficient digital certificate processing. In one aspect a system for efficient digital certificate processing comprises a computer and a secure certificate cache coupled to a computer. The secure certificate cache stores pre-verified digital certificates. In a second aspect, a method for efficient digital certificate processing in a data processing system comprises providing a secure certificate cache and receiving a digital certificate. The method further includes determining if the digital certificate is within the secure certificate cache. The method finally includes verifying the validity of the digital certificate if the digital certificate is within the secure certificate cache. The system and method in accordance with the present invention provides efficient processing of digital certificates in that it advantageously avoids unnecessary repetitive verification of commonly used digital certificates and also requires less memory to verify a certificate chain than conventional systems. Pre-verified digital certificates are maintained in the secure certificate cache to facilitate accelerated certificate chain validation and avoid repeat verification in the future.
