【摘要】：弱仲裁量子签名的安全性依赖于量子力学的一些基本原理,其不仅比传统的数字签名具有更好的安全性,而且比仲裁量子签名计算效率较高.为此,给出了一种新型弱仲裁量子签名,该签名具有以下特点:(1)仲裁者并不参与签名的产生和验证过程,只在发生纠纷时,仲裁者才参与纠纷的解决;(2)通过利用签名者身份信息以及与密钥绑定的旋转算子对签名进行认证,可以抵抗伪造攻击,并具有不可否认性;(3)该签名方案具有基于身份的数字签名方案的优点,即用户的身份信息直接用作公钥,无须量子公钥证书,这将给用户提供更多的方便.
[Abstract]:The security of weak arbitration quantum signature depends on some basic principles of quantum mechanics. It is not only more secure than traditional digital signature, but also more efficient than arbitration quantum signature. In this paper, a new weak arbitration quantum signature is presented. The signature has the following characteristics: 1) the arbitrator does not participate in the process of signature generation and verification, and only in the event of a dispute. By using the signer's identity information and the rotation operator bound to the key to authenticate the signature, the arbitrator can resist forgery attacks. The signature scheme has the advantages of identity-based digital signature scheme, that is, the user's identity information is directly used as the public key and does not require the quantum public key certificate, which will provide more convenience to the user.
