Abstract

In this paper, we propose a new efficient identity based proxy signature scheme. Compared with the previously proposed proxy signature schemes, ours combines the properties of proxy signature and the identity based signature, and has much more advantages than the traditional proxy signature schemes without the identity based characteristic. In addition, we also modify the general scheme into an extensive version of multi-proxy and multi-signature, our multiproxy multi-signature scheme does not need any additional clerk to participate, and each proxy signer can act as a clerk, so it is very convenient to deploy and realize such kind of multi-proxy multi-signature scheme.
