On a zero-knowledge property of arguments of knowledge based on secure public key encryption schemes

Yodai Watanabe

Abstract

This paper considers a weak variant on the notion of zero-knowledge. The weak notion is compatible with the chosen ciphertext security. In fact, arguments of knowledge based on IND-CCA encryption schemes are shown to be statistical zero-knowledge in that sense.
