Abstract(in English) | Sanitizable or deletable signatures attract much attention because of their privacy-perserving property in which after generating a signature on an original document, partial information can be masked with keeping the integrity of disclosed part. Recently, Sano et al. combined these signatures into the sanitizable and deletable signature. However, there is a restrictions on subdocument status. In addition, possibilities whether similar signatures can be constructed was not discussed. This paper analyzes signatures of Sano et al., and constructs a new sanitizable and deletable signature with no restriction on subdocument status. Moreover, some similar siagntures are also constructed. |
