Two Improved Partially Blind Signature Schemes from Bilinear Pairings
A blind signature scheme is a protocol for obtaining a digital signature from a signer, but the signer can neither learn the messages he/she sign nor the signatures the recipients ...

Verifiable Signature Sharing
Abstract. We introduce Verifiable Signature Sharing (VCS), a cryptographic primitive for protecting digital signatures. VCS enables the holder of a digitally signed document, who m...

A Concealed t-out-of-n Signer Ambiguous Signature Scheme with Variety of Keys
In 2004, Abe et al. proposed a threshold signer-ambiguous signature scheme from variety of keys. Their scheme is a generalized case of the ring signature scheme, and it allows the ...

Divertible Protocols and Atomic Proxy Cryptography
Abstract. First, we introduce the notion of divertibility as a protocol property as opposed to the existing notion as a language property (see Okamoto, Ohta [OO90]). We give a defi...

Identity Based Threshold Ring Signature
In threshold ring signature schemes, any group of t entities spontaneously conscript arbitrarily n - t entities to generate a publicly verifiable t-out-of-n signature on behalf of ...
