DOI: 10.1007/s12652-018-0698-2
Abstract: As IoT technology evolves, developments of ubiquitous computing accelerates. At the same time, threats of privacy exposure also increase since the IoT systems expose the information such as user’s location or medical status collected from… read more here.

DOI: 10.1109/access.2020.2964686
Abstract: A lattice-based group signature scheme (LGSS) is an active cryptographic primitive, where each group member can sign messages anonymously in the name of the entire group and each valid signature should be traced to some… read more here.

DOI: 10.1109/access.2020.2997840
Abstract: As special ad-hoc networks, vehicular ad-hoc networks (VANETs) support vehicles to communicate with each other via opportunistic wireless links. In order to protect privacy of drivers, vehicles registered in VANETs are required to authenticate and… read more here.

DOI: 10.1109/tetc.2021.3062348
Abstract: In contrast to the traditional cloud-based IoT structure, which imposes high computation and storage demands on the central cloud server, edge computing can process data at the network edge. In this paper, we present an… read more here.

DOI: 10.1109/tit.2020.2976073
Abstract: We solve an open question in code-based cryptography by introducing two provably secure group signature schemes from code-based assumptions. Our basic scheme satisfies the CPA-anonymity and traceability requirements in the random oracle model, assuming the… read more here.
