An Authentication Protocol in LTE-WLAN Heterogeneous Converged Network Based on Certificateless Signcryption Scheme With Identity Privacy Protection

Abstract

Aiming at to avoid the security drawbacks of the authentication protocol in Long Term Evolution-Wireless Local Area Network (LTE-WLAN) heterogeneous converged network proposed by the 3rd Generation Partnership Project (3GPP), an improved protocol based on hybrid cryptosystem is proposed to achieve access authentication for WLAN user equipment(UE) with identity privacy protection. The security analysis shows that by using certificateless signcryption(CLSC) scheme without pairing calculation based on Elliptic Curve Cryptography (ECC), hash chain and identity index mechanism, the proposed authentication protocol provides the following ten kinds of security properties: anonymous protection for International Mobile Subscriber Identity (IMSI), update on shared keys, protection for master session key(MSK), resistance to impersonation attack, replay attack, man-in-the-middle attack, redirect attack and Denial of Service (DoS) attack, mutual authentication between communication entities, and without framework modification from the original protocol. The performance analysis shows that the approximate calculation time of all the communication entities is 79 ms in total and that of UE is 266 us. Thus, our proposed protocol is superior to some other related improved protocols in terms of security and efficiency.

Blockchain-based differentiated authentication mechanism for 6G heterogeneous networks

“…The unified authentication of Identity-Based Cryptography (IBC) is realized among the access nodes. Cao et al [19] proposed an authentication protocol IEAP-AKA based on a hybrid cryptography system and certificate-free signature encryption in LTE-WLAN HetNets, and verified that the proposed method has higher security compared with the original EAP-AKA protocol. Liu et al [20] proposed authentication and key agreement protocol applied to Public Key Infrastructure (PKI) and CertificateLess Cryptography (CLC) environments, which implements secure communication between legally authorized users in heterogeneous IoT scenarios.…”

A Novel Security Scheme Supported by Certificateless Digital Signature and Blockchain in Named Data Networking

“…Certificateless signature schemes with batch verification could simultaneously verify the correctness of a large number of signatures from different signers for different messages, improving the efficiency of signature verification [29,30]. The integrated digital signature schemes have also attracted much attention [31,32] in order to support heterogeneous device environments where sensors in industrial IoT environments adopt ID-based cryptographic systems, and smart devices adopt CL-based cryptographic systems. Therefore, the certificate-less signature scheme has broad prospects for development and application scenarios and would become one of the important technological solutions for future digital signatures and identity verification.…”

Deep Neural Certificate less Hessian Heap Sign cryption for Secure Data Transmission in Wireless Network

“…This hybrid cryptosystem not only ensured access authentication but also ensured identity privacy protection. Yet another certificate less sign cryption method resisting to different types of attacks was presented in [7] to ensure security and efficiency. For flying ad hoc network, security concerns were addressed by employing certificate less key encapsulated sign cryption model in [8].…”
