An Implementation of a Pairing-Based Anonymous Credential System with Constant Complexity
Amang Sudarono, Toru Nakanishi, Nobuo Funabiki (Okayama Univ.) NS2010-135
Abstract (in Japanese) (See Japanese page) 
(in English) An anonymous credential system allows the user to convince a verifier of the possession of a certificate issued by the issuing authority anonymously.
A previously proposed system achieves the constant complexity for the number of attributes.
However, due to the use of RSA-based cryptography, it still suffers from a high cost computation.
Recently, we proposed an anonymous credential system with the constant complexity using a pairing-based accumulator.
In this paper, we present an implementation of the anonymous credential system in the application to an electronic identity card (eID).
We show the practicality of the system from experimental results that the processing times are less than a second.
