In view of this detail question, must obtain from keys production to try to eliminate the unsafe factor, obtains from the source, realizes in the mechanism to keys safe operation, prevents the key revelation to give the illegal user. How realizes to keys effective management constructs one of PKI systems important contents. The related question which this article is from produces from the key to is destroyed the entire process which involves to launch finally the elaboration, covered keys production, to load, the assignment, the memory, the renewal, the backup, to restore, contents and so on protection, cancel and destruction, proposed the solution key management difficult problem method. Followed the certificate life cycle entire stage, this article has been conducting the research to the key life cycle, finally completed a key management systems design with to realize.
