Strong authentication using dual SIM

Access to Internet services and home services demand proper authentication due to the increase of threats in the Internet. Passwords are not sufficiently strong while stronger authentication schemes are quite often expensive and complicated. This paper proposes a strong authentication scheme called Dual SIM authentication which makes use of two identical (u)SIMs in the authentication of the user upon access to services provided by a service provider or by himself from his home computer network. One SIM card located on the service side is used in the generation of authentication data while the other one located on the user side is participating to the authentication.
