Towards using multiple KGC for CL-PKC to secure D2D communications

The standardization of Device-to-Device (D2D) communication is underway by the Third Generation Partnership Project (3GPP) under the proposal Proximity Services (ProSe) which allows enabling direct communication between proximate devices [1]. Security of D2D communications must be assured in both scenarios: in coverage and out of coverage according to whether communication control is ensured by the Evolved Packet System (EPS) or the devices themselves. CertificateLess Public Key Cryptography (CL-PKC) [2] gives a serious solution for securing D2D communications. In this paper, we introduce a basic idea of a key management scheme based on CL-PKC, which aims to overcome security issues in all scenarios related to D2D communications and to deal with conflicting security requirements between privacy, anonymity, and traceability by the use of multiple Key Generator Centers (KGCs).
