理想格上强指定验证者的可截取签名方案.

Most of the existing content extraction signature schemes publicly verify signatures, but in some cases, they may compromise the signer's privacy. To enhance security and render the signature scheme resistant to quantum attacks, this paper proposed a new interceptable signature scheme based on the ring-SIS problem on the ideal lattice and integrated it with the strong specified verifier signature scheme. The scheme employed the anomaly abort technique of uniform sampling, capable of thwarting side-channel attacks. Additionally, this paper validated the security and correctness of the scheme. Compared to other schemes, this scheme exhibits clear advantages in security, number of repetitions, and signature size. [ABSTRACT FROM AUTHOR]
