Group signature with time-bound keys and unforgeability of expiry time for smart cities

Abstract: Internet of Things (IoT) lays the foundation for the various applications in smart cities, yet resource-constrained IoT devices are prone to suffer from devastating cyberattacks and privacy leak threats, thus are inevitability supposed as the weakest link of the systems in smart cities. Mitigating the security risks of data and the computing limitation of edge devices, especially identity authentication and key validity management of group devices are essential for IoT system security. In order to tackle the i… Show more

“…They used the properties of bilinear pairing operations to carry out batch verification. Group signatures with time-bound keys and batch verification are suggested as a result of the prior art in [44]. To provide conditional tracing, rapid verification, and dynamic device management, the group signature that is then proposed is implemented in both transactions and blocks.…”
