Confessible Threshold Ring Signatures
Yu-Shian Chen, Chin‐Laung Lei, Yun-Peng Chiu, Chun‐Ying Huang · 2006
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.
