A hi-speed system to execute certification path validation of the X.509 Certificate was developed. The algorithm used not only certificates and certificate revocation information but also certification path information as cached information in order to speed up transactions. The effect of it was confirmed by the performance experiment of the certification path validation system in test and real environment.
