Lightweight and secure D2D group communication for wireless IoT

Abstract

In recent years, wirless Internet of Things (IoT) technology has developed rapidly, and the reuse of spectrum resources, network efficiency, and the diversity of multi-communication scenarios have brought great challenges to the existing Internet of Things. And Device to Device (D2D) communication technology in 5th Generation Mobile Communication Technology (5G) has good application prospects in these aspects. Therefore, the combination with D2D can well solve the needs in the wirless Internet of things. However, safe and effective communication has become an urgent problem to be solved. In this paper, this paper proposes a D2D group communication protocol for wireless IoT in 5G. In this protocol, the Chinese remainder theorem is introduced into the protocol design, and a secure and efficient group authentication scheme is constructed based on secret sharing and Chebyshev Polynomials. The formal security proof using Burrows Abadi Needham (BAN) logic and informal security analysis show that our proposed protocol meets the security requirements. Through performance analysis, compared with other related schemes, this scheme not only provides better security, but also has obvious advantages in computation and communication efficiency.

A Trusted Internet of Things Access Scheme for Cloud Edge Collaboration

“…However, the attacker cannot obtain the user password, and it is difficult for the attacker to log in successfully and authenticate. (11) Forward security Assuming that the main key s of CSC is leaked and that the attacker has intercepted all communication content on the channel, they will want to crack the previous session key. At this point, the attacker needs to calculate SK 3 = H(CK 3 ||I 1 ||E 1 ||D 1 ||ID c ); however, the secret value of CK 3 is calculated using a chaotic mapping algorithm.…”

“…Recently, edge computing has been introduced. Edge computing is not a method to replace the cloud center, but rather to expand the capabilities of the cloud center [11]. As such, edge computing also has the security problems of cloud computing.…”

Secure and Lightweight Authentication Protocol in Internet of Things

“…This paper will adopt the universally considered threat model in the IoT security threat model [11]. Like most authentication schemes, this paper first considers the Dolev-Yao threat model [27].…”

“…As the increasing scale of terminal access devices and data, some criminals launch malicious attacks by finding, utilizing or controlling Internet of things devices with security vulnerabilities [10]. Therefore, security issues are not only related to the interests of users, but also have a great impact on economic development, social stability and national security [11]. Here, we need to use cryptographic theory and technology to build a scheme to provide a comprehensive security mechanism.…”
