Abstract:
The present invention is applicable to the technical field of communications. Provided is a method for generating a dynamic login credential, comprising the steps of: if data interaction occurs between a server and a communication terminal, updating at least one dynamic key according to a pre-determined key updating algorithm; when a dynamic login credential reaches a pre-determined update period, judging whether the dynamic key is updated within the update period this time; and if the dynamic key is updated, according to a pre-determined credential updating algorithm and the updated dynamic key, updating the dynamic login credential. Accordingly, further provided is a system for generating a dynamic login credential. By virtue of this, in the present invention, the dynamic login credential is generated by means of the negotiation between the server and the communication terminal. By means of the continuous update of the dynamic login credential, even though the dynamic login credential is stolen by a violator at a certain moment, the security of the dynamic login credential can still be ensured after update, thereby protecting the security for the use by a user.
