Abstract

A sanitizable signature scheme is a signature scheme which allows a sanitizer to hide parts of the original message after the message is signed, without interacting with the signer. There exists many security models, properties and constructions for sanitizable signatures, which are useful in different scenarios. The aim of this paper is twofold.Firstly, we summarize different properties in the literature and gives some generic conversions between them. We propose a security model to capture most of these properties.Secondly, we present the first concrete construction of sanitizable signatures which is proven secure in the standard model.
