A sanitizing signature scheme, which is a variant of digital signatures, enables a trusted party named sanitizer to modify parts of signed documents without corresponding to the signer. A lot of sanitizing signature schemes have been proposed since 2001. However these schemes are suitable for table-style documents, but none of them are considered for story-style documents. We consider that the solution...
The notion of limited verifier signature (LVS) was first introduced by Araki et al. in 1999. It is a useful cryptographic primitive to limit the publicly verifiable property of ordinary digital signatures. In a LVS, the signature can be verified by a limited verifier. When necessary, the signer or the limited verifier can provide a proof to convince a designated verifier (eg., a judge) that the signer...
