The Internet has consolidated itself as a very powerful platform that has changed the communication and business way. Nowadays, the number of users navigating through Internet is about 1,552 millions according to Internet World Stats. This large audience demands online commerce, e-government, knowledge sharing, social networks, online gaming . . . which grew exponentially over the past few years. The security of these transactions is very important considering the number of information that could be intercepted by an attacker. Within this context, authentication is one of the most important challenges in computer security. Indeed, the authentication step is often considered as the weakest link in the security of electronic transactions. In general, the protection of the message content is achieved by using cryptographic protocols that are well known and established. The well-known ID/password is far the most used authentication method, it is widely spread despite its obvious lack of security. This is mainly due to its implementation ease and to its ergonomic feature: the users are used to this system, which enhances its acceptance and deployment. Many more sophisticated solutions exist in the state of the art to secure logical access control (one time passwords tokens, certificates . . . ) but none of them are used by a large community of users for a lack of simplicity usage (O'Gorman, 2003)...
