英文摘要 | Device-to-Device (D2D) communications and the fostered services have been expected to play a key role in the next generation mobile communication networks (5G) and the Internet of Things (IoT) ecosystems. D2D Group Communications (D2DGCs) push forward the technology of two-device communications to that for group of device communications. However, they also expose new security threats and raise great privacy concern. Resource-and-battery constraints in the terminal devices further amplify the challenges of designing secure D2DGC. Existent Privacy Preserving Authenticated Key Agreement (PPAKA) schemes for D2DGC are far from being practical in terms of their computational complexities and weak fault-tolerance. This paper, based on the Modified Computational Diffie-Hellman Problem (MCDHP) and the proposed Certificate-Less Aggregate Signature (CLAS) scheme, proposes a new Privacy- Preserving Authenticated Key Agreement (PPAKA) scheme which greatly improves the computational performance, the communication performance, and the fault tolerance. The improvements are amplified as the number of devices in a group increases. The analysis shows that that, even for the smallest group of two devices, a device in our scheme only demands 4% the computational complexity of Wang-Yan’s PPAKA-Identity-Based Signature scheme, which is the state of the art scheme for privacy-preserving D2DGC. |
