The recent advancement in wireless body area networks (WBAN) plays an important role in remote health care systems. However, these networks are suffering from data security and privacy threats. Lack of anonymous authentication and secure data communication leads to operation failure in WBAN. Computational cost and privacy preservation are the two major hindrances for anonymous authentication in many existing schemes. Therefore, a secure and efficient privacy-preserving anonymous authentication scheme is proposed to provide data security and privacy to the users with low computational and communication cost. The performance analysis and experimental simulation results ensure that our proposed anonymous authentication method outperforms the existing systems in terms of providing data security and privacy with less computational overhead.
Automatic Dependent Surveillance-Broadcast (ADS-B) system provides significant improvements in air traffic control system such as optimal routing in non-radar environments with a new level of safety and efficiency. The ADS-B system is being installed in many aircrafts in recent year. The ADS-B equipped aircraft broadcasts the air traffic information to nearby aircraft and ground stations either once or twice per second.Because of the open channel communication atmosphere, the ADS-B system is affected by many security attacks. Many authentication and batch verification schemes are available to provide data integrity and source authentication for the ADS-B system. But they are suffering from computational overhead and communication overhead. Hence, an efficient anonymous authentication scheme is proposed for the ADS-B system with batch verification based on Message Recovery Signature (MRS). The security and performance analysis section ensure that the proposed scheme provides essential security features with less computational and communication overhead comparison with the other existing schemes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
