A fully dynamic authentication method without identifier is disclosed in the present invention. The user's original identification code and authentication code having been encrypted dynamically will be transmitted by the user terminal to the server, and will be decrypted there for identification confirmation. In the authentication method of the invention, the identification code and authentication code are encrypted and decrypted unitedly. The results of each encryption are different from all others and there is no a static identification code or feature to be identified each time the user's identification is authenticated, therefore the hacker would not be able to trace, record and analyze the user's authentication information. Thus actually the cracking object of the hacker has to be changed from the variation law of a single user to those of all users, which provides higher security. <IMAGE> |
