Abstract

This work proposes a reparation to the flaw in the paper of Blazy et al. (IEEE 2017). The flaw lies in the proof of the unforgeability property. More precisely, the way of handling collisions and of using the adversary to solve the challenge problem are incorrect. This problem is circumvented by adding a proof of knowledge of the randomness. It results in a scheme with the same public key size as that of the previous one, the size of the signature is a little bit larger.
