We propose a new identity based multi-proxy signature system. Compared with the previous some ones, we firstly implement one original signer authorizing a group of persons, called proxy signers, sequentially to make signature on behalf of original signer. Also, the system combines the property of the identity based signature, and has much more advantages that the traditional multi-proxy signature schemes without the identity based characteristic. The protocol can stop to perform in any one proxy signer. At that time, this proxy signer's signature is a valid signature too.
