A NOVEL PROTOCOL FOR INDIRECT AUTHENTICATION IN MOBILE NETWORKS BASED ON ELLIPTIC CURVE CRYPTOGRAPHY
P. Rajeswari, K. Thilagavathi · 2009
Unlimited mobility free of any fundamental communications is presented by Mobile Networks. In such networks, the information access between unacquainted nodes and server is a usual thing that happens frequently. This creates more chance to take the advantage of accessing information illegally by any invalid user node. The threat of apprehensive surroundings, information mishandling, etc is the eventual outcome. The fortification of classified and susceptible data in mobile networks can be done by the vital system, cryptosystem that spots the legitimacy. In such circumstances, the fundamental pre-requisite for better authentication is the performance of authentication by a middle agent, say Authentication server. Hereby, we are proposing a protocol that provides a secure transfer of information between the both unaccustomed parties. The most common public-key cryptographic scheme, elliptic curve cryptography is exploited to devise the protocol. Subsequently, the mobile networks employ the protocol for the authentication of user node. As the protocol utilizes the elliptic curve cryptography, it offers security more than enough with a reasonable key length. Hence the protocol develops an environment in which the user node which is unfamiliar to the Main server can transfer information without any eavesdropping of unauthenticated nodes.
