Abstract

The invention provides a method for key protection and a system for the key protection. The method for the key protection includes that a mobile terminal receives a registration instruction and generates a user public key and a user private key according to the registration instruction; when the mobile terminal is subjected to identification authentication by a mobile banking server and a bank comprehensive front server, the mobile banking server sends the user public key to a third-party e-commerce authentication server for certified signing so as to generate a user public key certificate and store the user public key certificate; the mobile banking server carries out an authentication process to encrypted user transaction information sent by the mobile terminal according to the user public key certificate, and when the authentication is passed, the bank comprehensive front server executes a transaction; and after the transaction is finished, the mobile terminal generates an updated private key protecting parameter and sends the updated private key protecting parameter to the mobile banking server, and then the mobile terminal receives an update success result from the mobile banking server and encrypts and stores the user private key according to the updated private key protecting parameter. The method for the key protection and the system for the key protection can increase attack difficulty and improve safety.
