An anonymous authentication scheme for edge computingbased carhome connectivity services in vehicular networks Abstract   With the rapid development of Internet of Things technology, the interconnection between objects has become more and more popular, particularly in the fields of smart home and intelligent transport systems. Carhome connectivity services allow the user to monitor and control home appliances while driving a car on the road. Such services can be deployed on edge servers in vehicular networks for low latency and user privacy. However, privacy issue is a big challenge for this application since userxe2x80x99s sensitive information such as driving route, home location, even connection between car and home are vulnerable to be disclosed and abused. To address this issue, the paper proposes an anonymous authentication scheme based on efficient cryptographic building blocks for privacypreserving carhome connectivity services. The scheme covers the IEEE standard WAVE stack and the higher layer facilitating anonymous authentication for security services. As a result, it allows the user driving in a car to interact with home appliances without sensitive information being leaked to any edge server or roadside unit. Meanwhile, a misbehaving user can be inspected against anonymity with hisher identity being retrieved by authority. The performance analysis shows that the proposed anonymous authentication scheme outperforms some other related works in vehicular network environment, with respect to communication overhead, computation overhead, signaling cost, serving ratio, and authentication delay.

IoTBased Anonymous Authentication Protocol Using Biometrics in Smart Homes The smart home is increasingly being considered as one of the Internet of Things applications. With the development of mobile networks and the speed of data transfer, the expansion of smartphones and increasing of interest in raising the safety factor in personal life, many companies have entered the smartphone market. With the help of the Internet of things portal, it is possible to monitor wireless sensors and use noncomputerized alert systems. Therefore, it is essential to secure such a system to create a sense of relaxation in the lives of users and homeowners to deal with possible occurrences. The integration of technologies for the automation of home affairs with the Internet of things means that all physical objects can be accessed on cyberspace; therefore, the concerns raised by users about the lack of privacy and security are a serious argument that science and technology should answer. This paper proposes an anonymous secure framework in connected smart home environments, using solely lightweight operations. The proposed framework in this paper provides efficient authentication and key agreement, and enables devices (identity and data) anonymity and unlinkability. It is demonstrated that computation complexity of the proposed framework is low as compared to the existing schemes, while security has been significantly improved. The proposed scheme assures us that even if the home owneru0027s device is attacked, the rest of the system will continue to work properly.
