With the development of mobile commerce,WPKI attracts more emphasis.As WPKI users are very large and WTLS certificates need to be renewed frequently,WPKI has to support on-line CAs.To guarantee the security of CAs,it is necessary to tolerate faults and intrusions.The article brings about a new fault-tolerant scheme about WPKI/CA.The new system supports distributed certification service and avoids single-failure.It can tolerate not only extern intrusions,but also internal fault activities.It would satisfy practical network environment.At the same time,the PK recovery mechanism is proposed.The fault-tolerance and robustness of the whole system is improved.
