Abstract

Anonymous Attribute-Based Credential (ABC) schemes allow users to anonymously prove the ownership of their attributes, such as age, citizenship, gender. The ABC schemes are part of a larger group of cryptographic constructions called Privacy Enhancing Technologies (PETs), aiming to increase user's privacy. In the article, we present a new ABC scheme based on elliptic curves and HM12 scheme. The scheme provides anonymity, untraceability, unlinkability, selective disclosure of attributes, non-transferability, revocation and malicious user identification. By involving elliptic curves, we achieved faster verification phase (by 30%) and smaller communication cost between user and verifier (by 85%) compared to the original HM12 scheme, with equivalent or greater security level.
