Abstract

Optical fiber communication system plays an important role in the field of data communication which has strict requirements for high-speed, reliable and real-time data transmission. Therefore, in order to ensure the security of data transmission, we should strengthen the security requirements of optical fiber communication system in this aspect. Based on the discrete logarithm problem, this paper proposes the first log-sized traceable ring signature scheme with DualRing, a new construction paradigm designed by Yuan et al. The scheme has the function of digital signature technology to ensure that the information is not tampered with, which can ensure the anonymity of real users and avoid the excessive anonymity of dishonest users. Next, we prove the security of two schemes: unforgeability, traceability and anonymity. Finally, the communication and calculation costs are analyzed, and the comparison results show that the two schemes are more efficient.
