Abstract: This paper proposes an improved multi-proxy signature scheme. The improved scheme is constructed from bilinear pairings using BLS short signatures. Due to the use of short signatures, the scheme is not only efficient, but also satisfies all the security requirements of the strong proxy signature. It is proved that the design is available and feasible. It reduces the influence of attack.

Key words: Short signature, Multi-proxy signature, Bilinear pairings
