Proficient Secrecy Roaming Conserving Security in Wireless Mobile Networks

Increasing number of mobile users is being allowed to use wireless mobile network services where the roaming service provides the constant services to a network without breaking the connection. Ensuring security in roaming service is a great challenge. In the absence of home server the inter-domain security should be established which makes it feasible for mobile users to move into the foreign domains. An authentication mechanism is required between the mobile users and the foreign server which supports the highly secured communication in wireless networks. In addition maintaining the privacy of the mobile user is an important requirement such as the information about behavior of the user who needs the roaming service. The participations of home attendants have engrossed significant interest to its stimulus on the communication proficiency. Formal protocols incur high communication and computation cost. The proposed protocol that has a novel three-round architecture which uses a pseudo-identity based signcryption scheme to perform efficient revocation with short revocation list and the authentication efficiency is higher than that of existing protocols. To provide the better computation efficiency and lightweight storage efficiency this scheme does not require the highest computational cost on the roaming user. A detailed analysis and overhead evaluation on a number of performance metrics such as computation cost and time is given to validate the performance of proposed protocols.
