Linkable ring signatures not only inherit the advantages of ring signatures, but also embed link tags in the signature scheme, enabling verifiers to determine whether two signatures are generated by the same signer, which addresses the issues of abuse or repeated signatures effectively. The CertificateLess Public Key Cryptography (CL-PKC) system can solve the problems of key escrow and certificate management, thereby enhancing security. By combining the advantages of the above two, a CertificateLess Linkable Ring Signature scheme (CL-LRS) based on elliptic curves was proposed, the system model and security model of the scheme were constructed, and the scheme was proven secure against Type Ⅰ/Ⅱ adversary attacks under random oracle model with anonymity, unforgeability, linkability, and non-slanderability. To verify the practical performance of the proposed scheme, the signature overhead and signature verification overhead of the proposed scheme were compared with those of several existing elliptic-curve-based ring signature schemes by calculating the time of each cryptographic operation used in the signature scheme. Experimental results indicate that without relying on bilinear pairing operations, the proposed scheme can still resist attacks from malicious Key Generation Centers (KGCs) and prevent potential signature abuse. Meanwhile, the total signature time of the proposed scheme is reduced by 80.1% compared with that of the elliptic-curve-based linkable ring signature. It can be seen that the scheme is suitable for applications in resource-constrained scenarios.
