Proxy Blind Signature Scheme

Amit K Awasthi and Sunder Lal

Abstract

Blind signature is the concept to ensure anonymity of e-coins. Untracebility and unlinkability are two main properties of real coins, which require mimicking electronically. Whenever a user is permitted to spend an e-coin, he is in need to fulfill above requirements of blind signature. This paper proposes a proxy blind signature scheme with which a proxy is able to make proxy blind signature which verifier is able to verify in a way similar to proxy signature schemes.

Note: There was a misprint 2.1.2 (2). Now it has been removed.
