Confessible Threshold Ring Signatures

Confessible Threshold Ring Signatures

We present two threshold ring signature schemes with different properties. One focuses on the confessibility (or signer verifiability) and the denouncibility properties. The other focuses on the threshold-confessibility. Our schemes are built on generic ring signature schemes and can be easily adapt...

Zusammenfassung:We present two threshold ring signature schemes with different properties. One focuses on the confessibility (or signer verifiability) and the denouncibility properties. The other focuses on the threshold-confessibility. Our schemes are built on generic ring signature schemes and can be easily adapted to most existing ring signature schemes. Based on the former works, we also construct a realization of our schemes as an example. We prove that our schemes are secure in the random oracle model.
