Remote User Authentication Scheme in Multi-Server Environment Using Smart Card
In a single server environment, one server is responsible for providing services to all the authorized remote users. However, the problem exists if a user wishes to access several network services. To overcome this weakness, various multi-server authentication schemes have been proposed. Though, these schemes are exposed to one or the other network security attack. This paper suggests robust multi-server authentication scheme using smart cards. Its security is based on cryptographic one-way hash function and the discrete logarithm problem. This scheme allows remote users to access multiple servers without separately registering with each server.
