1. A method for authenticating a web site, comprising the steps of:
- computing a dynamic code;
computing a first one-time password corresponding to the computed dynamic code;
transmitting the dynamic code to the web site;
computing, by the web site, a web site computed one-time password corresponding to the dynamic code; and
comparing the first computed one-time password to the web site computed one-time password, in order to authenticate the web site.

Abstract
An authentication system is provided that includes a portable device and a decryption node. An individual uses the portable device, such as a portable device like a cell phone to compute a challenge and a response. The challenge and response is sent to a decryption node. In response, the decryption node computes a presumed response and compares the presumed response to the response of the portable device, in order to authenticate the individual associated with the portable device.

7. A method for authenticating a web site, comprising the steps of:
-
computing a displayable and human readable dynamic code; computing a first one-time password corresponding to the computed dynamic code; transmitting the dynamic code to the web site; transmitting the dynamic code to a third party entity server; computing a server computed one-time password that corresponds to the dynamic code received by the server; receiving by the web site the server computed one-time password corresponding to the dynamic code; and comparing the first computed one-time password to the web site transmitted one-time password, in order to authenticate the web site. - View Dependent Claims (8)
