摘　　要：将可转换不可否认签名方案的思想方法应用到NIDV不可否认签名方案中,使其具有可转换为普通自验证签名的性质,提出了一个可转换NIDV不可否认签名方案,并给出了随机预言模型下的安全性证明.Non-interactive designated verifier undeniable signatures only allow the designated verifier to participate the confirmation and denial protocol. Practical applications may need to cancel restrictions on the verifier of in the future. It is said that anyone can participate in the signature confirmation and the deni- al. This article applied the methods of convertible undeniable signature scheme to the NIDV undeniable signature scheme, so that it can be converted into ordinary signatures. We proposed a convertible NIDV undeniable signature scheme together with the security proofs under the random oracle model.
