Real time communication protocol of identification based on zero - knowledge proof 保密通讯中基于零知识证明的身份认证协议
( 4 ) apply zero - knowledge proof into digital watermarking verification and present a kind of watermarking verification protocol ( 4 )将零知识证明应用于数字水印认证,提出数字水印基础设施中的一种数字水印认证协议。
In zero - knowledge proofs , a person ( or device ) proves that he or she knows a secret without revealing it , like opening a combination lock without giving away the actual combination 在零知识证明之中,一个人(或装置)无须揭露机密,也可以证明自己确实知道这个秘密,就好像不必说出真正的密码组合,就可以打开密码锁一样。
The idea of zero - knowledge proof is used in key updating protocol - , the signature protocol - , validity verification protocol of signature and the verification protocol of forward security . it can guarantee that the new scheme is more secure and efficient than previous schemes 对新方案的密钥更新协议、签名协议、签名的有效性验证协议、前向安全性验证协议用了零知识证明的思想,具有更高的安全性和效率。
Finally , a new threshold and confirmer signature scheme for group or organization is proposed by using the multiplicative secret sharing and rsa public key cryptosystem , whose confirming and denying protocols are constructed by using the idea of zero - knowledge proof 提出适合于团体和组织的门限证实数字签名方案。新方案以乘法秘密共享和rsa加密算法为基础,采用一次性零知识证明思想构建签名的证实协议和否认协议。
The topics covered in this course include interactive proofs , zero - knowledge proofs , zero - knowledge proofs of knowledge , non - interactive zero - knowledge proofs , secure protocols , two - party secure computation , multiparty secure computation , and chosen - ciphertext security 本课程所涵盖的主题包含有互动式证明,零知识证明,知识的零知识证明,非互动式零知识证明,安全协定,双方安全计算,多方安全计算与选择密文安全性。
The digital signature algorithms with special attributes are studied , and the new digital signature scheme , a undeniable forward - secure digital signature scheme based on zero - knowledge proof , is proposed based on the difficult mathematic problems . it is the first time that the undeniable property and the forward - secure property are combined in a digital signature scheme 以数学中的困难问题为理论基础研究了具有特殊性质的数字签名算法,提出了满足特殊需求的新的数字签名算法- - - -基于零知识证明的不可否认前向安全数字签名算法,首次将不可否认数字签名与前向安全数字签名结合起来。
Caronni presented the conception of " digital watermark " in 1993 firstly . [ 8 - 11 ] in order to transfer digital watermarking skill from theoretic to reality , this article researches it from the angle of application . we apply agent , zero - knowledge proof into the area of digital watermarking , and try to construct feasible and integrated digital watermarking system 为了将数字水印技术由理论变为现实,本文从实际应用的角度出发,从三个方面对数字水印进行了研究,将agent 、零知识证明等应用于数字水印领域,并借鉴目前较为成熟的密码学和pki ca建设经验,尝试构建可行的完备数字水印系统的方法。
