An Improved GN-AK Protocol Using Double-Base Scalar Multiplication and Point Halving over Elliptic Curves

Applied Sciences
Starting from the basic form of GN-authenticated key agreement (GN-AK), the current research proposes an improved protocol by integrating a new scalar multiplication technique based on a dual-base chain representation with bases 1/2 and 3.

New Blind Muti-signature Schemes based on ECDLP [PDF]

International Journal of Electrical and Computer Engineering (IJECE), 2018
In various types of electronic transactions, including election systems and digital cash schemes, user anonymity and authentication are always required. Blind signatures are considered the most important solutions to meeting these requirements. Many studies have focused on blind signature schemes; however, most of the studied schemes are single blind ...

Multi‐hop anonymous payment channel network based on onion routing

IET Blockchain, Volume 4, Issue 2, Page 197-208, June 2024.
To solve the payment channel network path privacy problem, we analyse the multi‐hop anonymous and privacy‐preserving payment channel network scheme and propose a multi‐hop anonymous payment channel network based on onion routing based on it. The scheme removes the routing assumptions of the original scheme, designs an onion routing‐based payment ...

A Novel Security Scheme Supported by Certificateless Digital Signature and Blockchain in Named Data Networking

IET Information Security, Volume 2024, Issue 1, 2024.
Named Data Networking (NDN) is a promising network architecture that differs from the traditional TCP/IP network, as it focuses on data rather than the host. A new secure model is required to provide the data‐oriented trust instead of the host‐oriented trust.

(t, n) threshold secret sharing scheme without SDC

Tongxin xuebao, 2006
By means of the intractability of ellipse curve discrete logarithm problem（ECDLP）,a（t,n） secret sharing threshold scheme based on ellipse curve cryptography was proposed.Generally speaking,there are two kinds of threshold schemes: a threshold scheme with
