“…Harn et al [44] presented a novel design of group key distribution using only the logic exclusive-or (XOR) operation, and demonstrated its applications in various network models. A group key distribution scheme was introduced by [45] for a large size of group communication.…”

“…Tselikis et al [47] proposed an anonymous conference key distribution system, based on the elliptic curves, one-way hash functions and random pseudonyms. However, all the works of [44][45][46][47] introduced neither three-factor nor biometric-based authentication in their schemes. A secure authentication and group key distribution scheme for resource-limited Wireless Body Area Networks (WBANs) was proposed by Tan and Chung [48].…”

Fifth generation (5G) mobile technology enables a new kind of network that provides high peak data rates, ultra-low latency communication and high user density. Electronic healthcare (e-health) allows the data to be stored and shared in a highly efficient and flexible manner. Group e-health services help in improving long-term results of the treatments due to its collaborative characteristic. The services including real-time remote patient monitoring and transmission of large health data files can be facilitated by e-health systems enabled with the 5G network. Since the communication channel is open, security and privacy in the system should be taken into account. Our work proposes a key distribution scheme for group healthcare services in 5G network environments. We construct various healthcare domains and apply the proposed scheme to the group services. The paper also introduces Single Sign-On (SSO), a cost-efficient solution, for multi-server architecture of the constructed system. Security and privacy of the scheme are enforced by a three-factor authentication mechanism (integrating smart card, password and biometrics) and strong user anonymity property. We provide security proof of the proposed scheme using various well-known tools including RoR model, BAN logic and AVISPA simulation. Results of various performance comparisons indicate that our scheme provides most functions and bears rational costs, compared with its related works.

“…Two papers recently published by Harn et al [6,7] propose some very simple key distribution schemes designed to enable two or more parties to establish a shared secret key with the aid of a third party. Unfortunately, as we show, most of the schemes are inherently insecure and all are incompletely specified.…”

This is followed by analyses of the various proposed protocols: Sections 3, 4, 5 and 6 provide analyses of the four protocols in the first paper [7], and Section 7 briefly examines the almost identical protocols in the second paper [6]. Finally, Section 8 concludes the paper.…”

“…The two papers, whilst having very closely-related content and the same set of authors, do not refer to each other, and it is hard to know which was submitted first. For simplicity we refer throughout to Paper A [7], and Paper B [6]. Since the two schemes in Paper B [6] both appear to be slightly elaborated versions of two of the schemes in Paper A [7], we consider Paper A first.…”

With rapid development of next-generation mobile networks and communications (5G networks), group-oriented applications in resource-constrained smart environments (RSEs), such as smart homes and smart classrooms, have attracted great attentions. Due to the insecure communications between resource-constrained devices, secure group communications in RSE toward 5G face many challenges. In RSE toward 5G, lightweight communications and low computational overheads are crucial. Besides, the private tokens used to generate the group key are expected to be reused multiple times. However, the conventional frameworks for secure group communications cannot meet these requirements. A practical construction of extremely lightweight constant-round membership authenticated group key establishment framework is proposed in this paper for RSE toward 5G, which not only implements identity authentication among the members and group key establishment but also ensures extremely lightweight computation and communication costs by each group member. In our proposed scheme, the increase in the number of group members will not lead to a linear or logarithmic increase in the communication and calculation costs at the member side. Our framework also resists external and internal attacks and meets all the desirable security features. In this framework, the privacy of tokens can be well protected, so that they can be reused for multiple times. Therefore, our scheme significantly reduces the costs of communication and calculation, and it is more efficient compared with the related schemes in the literature. This proposal is fairly suitable for lightweight membership authentication and group key establishment in RSE toward 5G.
