Summary :

In this paper, we present a framework to construct message recovery signature schemes from Sigma-protocols. The key technique of our construction is the redundancy function that adds some redundancy to the message only legitimately signed and recovered message can have. We provide a characterization of the redundancy functions that make the resulting message recovery signature scheme proven secure. Our framework includes known schemes when the building blocks are given concrete implementations, i.e., random oracles and ideal ciphers, hence presents insightful explanation to their structure.
