New DLOG-Based Convertible Undeniable Signature Schemes in the Standard Model

Abstract

We propose discrete-logarithm-based undeniable signature schemes supporting both selective and all conversion, with formal security analysis in the standard model. The schemes are the first practical ones of their type, enjoying relatively short signatures and efficient confirmation/disavowal protocols, while for security relying on the strong Diffie… (More)
