Abstract:
1. A method of authenticating a user on a network, comprising: receiving, by a security server, a request of a network site for authentication of the user; calculating, by the security server in response to the receipt of the authentication request, a one-time-password based on (i) a secret shared by the security server and the network site but not by the user, and the secret is not shared or associated by the security server or the network site with the user, and (ii) a one-time-password generating algorithm, wherein the one-time-password is independently calculable by the network site based on the shared secret and the one-time-password generating algorithm; transmitting, by the security server to the network site, a time stamp or counter value associated with the calculated one-time-password; and transmitting, by the security server to the user, the calculated one-time-password to authenticate the user to the network site.
