DAA: Fixing the pairing based protocols
Liqun Chen, Paul Morrissey, Nigel Paul Smart · IACR Cryptology ePrint Archive · 2009
In [17, 18] we presented a pairing based DAA protocol in the asymmetric setting, along with a “security proof”. Jiangtao Li has pointed out to us an attack against this published protocol, thus our prior work should not be considered sound. In this paper we give a repaired version, along with a highly detailed security proof. A full paper will be made available shortly. However in the meantime we present this paper for the community to check and comment on.
