Certificateless strong designated verifier multi-signature

open access: yesTongxin xuebao, 2016
In order to satisfy the application requirements in the fields of judicial administration,e-government,etc.,the definition and security model for certificateless strong designated verifier multi-signature were proposed.Then,the first certificateless ...

Polynomial approximation of bilinear Diffie–Hellman maps

open access: yesFinite Fields and Their Applications, 2008
Let \(p\) b an odd prime and \(\mathbb{F}_q\) the finite field of characteristic \(p\) with \(q\) elements, \(E\) an elliptic curve defined over \(\mathbb{F}_q\), \(\ell\) a prime different from \(p\) dividing the order \(|E(\mathbb{F}_q)|\), \(P\in E(\mathbb{F}_q)\) a point of order \(\ell\) and \(m\) the order of \(q\) (modulo \(\ell\)). The bilinear

Curve25519: New Diffie-Hellman Speed Records [PDF]

open access: yes, 2006
This paper explains the design and implementation of a high-security elliptic-curve-Diffie-Hellman function achieving record-setting speeds: e.g., 832457 Pentium III cycles (with several side benefits: free key compression, free key validation, and state-of-the-art timing-attack protection), more than twice as fast as other authors' results at the same

Strongly secure certificateless one-pass authenticated key agreement scheme

open access: yesKuwait Journal of Science, 2015
As certificateless public key cryptography (CLPKC) could solve the problem of keyescrow, recently it has been studied more and more. Certificateless authenticated keyagreement (CLAKA), as an important part of the CLPKC, also attracts ...

The n-Diffie-Hellman Problem and Its Applications

open access: yes, 2011
The main contributions of this paper are twofold. On the one hand, the twin Diffie-Hellman (twin DH) problem proposed by Cash, Kiltz and Shoup is extended to the n-Diffie-Hellman (n-DH) problem for an arbitrary integer n, and this new problem is shown to be at least as hard as the ordinary DH problem.
