Abstract:
1. A computer-implemented method for providing message authenticity for a message by an originating user to a recipient's computer, the method comprising the steps of: accepting, through the recipient's computer, from the originating user: decrypting the key management component, through the recipient's computer, to yield (a) a key which decrypts the user authentication key and (b) a message integrity key, wherein the entropy of the user authentication key is less than the entropy of the message integrity key; decrypting the authenticator component, through the recipient's computer, using the key which decrypts the user authentication key; authenticating the user, through the recipient's computer, using the authentication data; accepting, through the recipient's computer, a message comprising message data from the originating user's computer; and validating the message integrity component through the recipient's computer using the message integrity key and the message data, thereby validating the message.
