Abstract

See full text

A technique for providing message authenticity includes accepting transaction information, accepting a first data item used for authenticating an originating user, cryptographically processing the transaction information using only a second data item, wherein the entropy of the first data item is less than the entropy of the second data item, and authenticating the originating user using the first data item. The first data item can be a sequence of digits corresponding to those displayed on an external device, such as, for example, an RSA authorization token, credit card, etc.
