Sanjeet Kumar Nayak, Banshidhar Majhi, Sujata Mohanty · 2013
In this paper we presents an Elliptic Curve Discrete Logarithm Problem (ECDLP) based blind signature scheme. Elliptic Curve Cryptosystem is the best known public-key cryptosystem till date, and is suitable for resource constrained environment because of smaller key size. The proposed scheme is untraceable and proved to be resistant against active attacks. The scheme is also universally verifiable. We compared the performance with some existing scheme and found that, the computational overhead of the proposed scheme is very low. Hence it can be applicable to real life scenarios, such as, e-voting, e-cash and e-commerce applications.
