New Proxy Signature, Proxy Blind Signature and Proxy Ring Signature Schemes from Bilinear Pairing
Fangguo Zhang and Reihaneh Safavi-Naini and Chih-Yin Lin
Abstract: Proxy signatures are very useful tools when one needs to delegate
his/her signing capability to other party. After Mambo $et\ al.$'s
first scheme was announced, many proxy signature schemes and
various types of proxy signature schemes have been proposed. Due
to the various applications of the bilinear pairings in
cryptography, there are many ID-based signature schemes have been
proposed. In this paper, we address that it is easy to design
proxy signature and proxy blind signature from the conventional
ID-based signature schemes using bilinear pairings, and give some
concrete schemes based on existed ID-based signature schemes. At
the same time, we introduce a new type of proxy signature -- proxy
ring signature, and propose the first proxy ring signature scheme
based on an existed ID-based ring signature scheme.
Category / Keywords: Proxy signature, ID-based cryptography, Proxy blind signature, Proxy ring signature, Bilinear pairings.
