Group key agreement protocol among terminals of the intelligent information system for mobile edge computing

Abstract

Security communication and information sharing among mobile devices are important application technologies of the intelligent information system (IIS). Because IIS is vulnerable to attacks, so the security of information sharing among mobile devices is seriously threatened. Thence, it is necessary to establish a secure channel for communication among mobile devices of IIS over an opening network. Group key agreement (GKA) can establish a secure channel among mobile devices of IIS by encryption technology. Due to the resource‐constraints of mobile devices, such as weak computing power, small storage capacity, and limited communication range. To address these issues, an asymmetric GKA protocol among terminals of IIS for mobile edge computing (GKA–IIS–MEC) network is proposed in this paper. Adopted asymmetric GKA to achieve the group secure communication mechanisms that message sender unfettered in this protocol; the protocol also uses edge computing environment to migrate the computation and communication loads of mobile devices of IIS to edge nodes, thereby ensuring that mobile devices have lightweight computation and communication loads; and the members participating in the GKA can verify whether the group session keys they calculated are correctness. Under the hardness assumption of bilinear inverse Diffie–Hellman problem, the proposed protocol is proven that it can resist negative attacks. After evaluating the performance of the protocol, GKA–IIS–MEC has higher efficiency than the referred works in terms of time cost, communication consumption, and computation consumption.

An Edge‐Cloud Collaborative Cross‐Domain Identity‐Based Authentication Protocol with Privacy Protection

“…Group key agreement protocol among terminals is proposed in Ref. [19]. This scheme defines the concept of multi‐authorization center identity authentication, which mainly includes three parts: initialization algorithm, key generation algorithm and authentication protocol.…”

“…only be deduced after the resetting period, the number of remaining codeword combinations can be determined by (2). This is done by multiplying the number of candidates as well as the average discrimination ratio.…”

“…Covert channels can be an effective and efficient means of transmitting confidential information in untrusted IoT networks. [1][2][3] The deployment of Voice over Long Term Evolution (VoLTE) for next-generation audio and video communication over mobile networks has significantly increased the available data rates and quality of service (QoS). [4][5][6] The core network of this technology is a packet-switched network, that is also part of the 5G standard.…”

A group key agreement protocol for intelligent internet of things system

“…It also proposes a specific conversion from AGKA without certificate authentication to AGKA without identity authentication based on session key. Group key agreement among intelligent terminals in intelligent system are proposed in Zhang et al 23,24 A scalable GKA protocol is proposed in Naresh et al 25 The flexible architecture proposed by the protocol not only reduces the process of cryptographic calculations, but also reduces the workload. The protocol adopts a hybrid and hierarchical approach to clusters, and the workload of key update is reduced without affecting other groups.…”
