Abstract:
Proxy blind signature, which combines the
properties of both proxy signature and blind signature. In
a proxy blind signature scheme, the proxy signer is
allowed to generate a blind signature on behalf of the
original signer. The proxy blind signature scheme is
useful in several applications such as e-voting, e-payment
and mobile agent environments. In this paper, we present
proxy blind signature scheme based on discrete logarithm
problem (DLP), which satisfy the security properties of
both the blind signature scheme and the proxy signature
scheme. Analysis shows that our scheme is secure and
efficient.
