Cryptanalysis of an ID-based Deniable Threshold Ring Authentication
[[abstract]]In this paper, we offer analysis of a deniable threshold ring authentication protocol proposed by Jin et al. [5]. The Authors in [5] combined the two concepts, namely, threshold ring signature and deniable authentication, to propose a non ...

碩士許多提供匿名性的可否認驗證協定都假設收送雙方事先已互相知道對方身份為基礎;而且為了防止傳送訊息洩露身份隱私,Hwang和Sung進一步提出第一個提供機密性、匿名性與公平保護的非互動式可否認驗證協定。然而,因為匿名的特性,使得事先已互相知道對方身份的假設並不實際。另一方面,Hwang和Sung所提出的協定中的機密性,其安全層級只達到IND-CPA。為了移除不實際的假設,並且提高機密性的安全層級至IND-CCA2,我們提出了可提供不可區分安全性與匿名性之非互動式公平可否認驗證協定 ...

Cryptanalysis on Improved Chou et al.\u27s ID-Based Deniable Authentication Protocol [PDF]
A deniable authentication protocol enables the protocol participants to authenticate their respective peers, while able to deny their participation after the protocol execution. This protocol can be extremely useful in some practical applications such as

碩士近年Hwang和Chao提出具匿名公平保護功能之互動式可否認認證協定,用於保護資料收送雙方的權益,然而他們的協定中對資料並無提供機密性保護,並採互動式設計,而影響協定整體的效能。一般而言,在傳輸效能上,非互動式協定較互動式協定有效率,但目前非互動式可否認驗證協定尚未對資料提供機密性保護,因此傳輸的資料有可能造成雙方權益的損失,進而對其他安全特性造成危害。為了有效地提供傳輸資料的機密性與可否認性,本論文首先提出第一套允諾簽密法;並藉由允諾簽密法的幫助,提出兩套具機密性、匿名性與收(送 ...

Deniable Authentication when Signing Keys Leak [PDF]
Deniable Authentication is a highly desirable property for secure messaging protocols: it allows a sender Alice to authentically transmit messages to a designated receiver Bob in such a way that only Bob gets convinced that Alice indeed sent these ...
