“…In our work, we effectively balance the functionalities of message trustworthiness, privacy, and accountability. As a conclusion, our scheme seems to be better and more robust than the schemes proposed in [31,45]. / = achieve the security component.…”

“…Then they demonstrated how this insoluble task might be reduced to the challenging challenge of identifying the pathways and cycles of Cayley graphs, including Hamiltonian paths and cycles. In [31,32], Gupta et al developed a novel undeniable signature technique in a non-abelian group over a group ring, whose security depends on the complexity of solving DLP and CSP. However, this approach needs a regular connection with the signer in order to validate the message and credentials, and the signer may not always be available.…”

“…However, this approach needs a regular connection with the signer in order to validate the message and credentials, and the signer may not always be available. Therefore, the scheme in [31,32] is impractical for business and confidential transactions. They claimed an undeniable signature is effective; a signer who has access to a private key may publish a publicly available message signature, which may compromise the confidentiality of the signer's identity.…”

“…The length of user-generated messages with an 80 bit security level may be calculated as 100 + 2 + 128 + 2 = 232 bytes if the payload, a time stamp, and a group ID are each represented by 100 bytes, 2 bytes, and 2 bytes, respectively. In Gupta et al [31], the length of the message is 640 bytes, while in Mittal et al [45], the message size is 450 bytes. Therefore, compared to [31,45], our protocol successfully achieves lower communication costs.…”

Group signatures are a leading competing signature technique with a substantial amount of research. With group settings, group signatures provide user anonymity. Any group member with access to the group can generate a signature while remaining anonymous. The group manager, however, has the authority to expose and identify the signer if required. Since the privacy of the sender should be preserved, this is a conflict between privacy and accountability. Concerning high performance on security, we propose a novel, well-balanced security and privacy group signature scheme based on a general linear group over group ring. To the best of our knowledge, our work represents the first comprehensive framework for a group signature scheme that utilizes generic linear groups over group rings. We demonstrate that the competing security goals of message trustworthiness, privacy, and accountability are effectively resolved by our protocol. The results of the performance evaluation and simulation demonstrate that our protocol achieves strong security, system robustness, and high-performance efficiency, making it suitable for practical applications.
