Secure Short Signature Scheme in Standard Model

This paper presents a novel and efficient short signature scheme.It is proven to be existential unforgeable under adaptive chosen message attack.The security of the signature scheme is reduced to the security of the q-SDH problem in the standard model.This paper analyses the efficiency of the signature scheme.Compared with the latest signature schemes secure in the standard model,the signature scheme is more efficient and suitable to be applied in the actual world.
