New Quantum Signature Scheme with Weak Arbitrator
- 分享到:
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.
Quantum signatures with weak arbitrator, whose security is based on some fundamental properties of quantum me-chanics ？ are believed to be more secure than the traditional digital signatures. They are more efficient than the quantum signa-tures with arbitrator. Then, a new quantum signature with weak arbitrator is proposed. Our scheme has the properties as fol-lows. （1） The arbitrator doesn？t involve the signing or verifying phase unless the disavowals occur. （2） The signature is veri-fied by using the identity information of the signer and the rotation operator combined with secret key, and it can resist against forgery attack and has the property of undeniablilty. （3） Our scheme has the virtues of the identity -based signature. That is, the signer＇s identity information is used as the public key. It does not need any quantum public - key certificate, so it can pro-vide more convenience for the users.
