A method and apparatus are provided for enhancing security for a private key or other multibit secure token code stored in a token by (a) assuring that the secure token code is not stored in the token except for short intervals when the token is actually in use by an authorized user and (b) by assuring that the secure token code cannot be obtained from the token except by an authorized user. This is accomplished by algorithmically combining a PIN or other secret code memorized by the user with the secure token code, either in the token or at a suitable terminal, to generate a meaningless multibit sequence/token secret which is stored in the token. The multibit sequence stored in the token is selected such that when it is algorithmically combined with the secret memorized code known only to the user, either in the token or at a terminal, it produces the private key or other secure token code.
Apparatus for providing enhanced security for a multibit secure token code which is obtained from a token, the apparatus comprising:
Apparatus for providing enhanced security for a multibit secure token code which is obtained from a token, the apparatus comprising:
Apparatus for providing enhanced security for a multibit secure token code which is obtained from a machine readable token, the apparatus comprising:
A token having a memory element for storing a selected multibit sequence which is used under selected conditions to generate a desired multibit secure token code unique to a token user, which token is formed by the process of:
