In secure roaming service, the foreign server must authenticate the roaming user, who originally subscribed to the home server. Hence, an authentication mechanism is currently important requirement for providing secure roaming services and protects the location privacy of users on unidentified authentication. The unidentified authentication will process without participating the home server on efficiency communication for existing work. The process of authentication increases high computation costs and huge revocation lists. The novel three-round anonymous (unidentified) roaming protocol uses a pseudo-identity-based signcryption scheme and using CK-model to perform efficient revocation with a short revocation list and efficient authentication. The use of a signcryption algorithm minimizes the storage in a Subscriber Identification Module (SIM) card with limited storage capacity. The authentication efficiency is also higher than that of existing protocols.
