WPKI plays an important role in mobile e-commerce,and the certificate retraction technology is its key component.The three common certificate retraction technologies in WPKI are analyzed and compared;the OCSP protocol can provide the real time service for certificate retraction,however,it is not suitable to be applied in WPKI immediately for the special restriction of WPKI.A design based on the OCSP protocol is provided,which is custom-built for the WPKI;several key technologies in its implementation are also described in detail to improve the efficiency and security of the system。
