Abstract
We propose a short signature scheme whose security is closely related to the discrete logarithm assumption in the random oracle model. The new scheme offers a better security guarantee than existing discrete-logarithm-based signature schemes. The main advantage of this scheme over the DSA signature scheme is that it has a one-fourth reduction in both the signature length and the verification computation; the level of security is preserved. The new short signatures are needed to low-bandwidth communication, low-storage and low-computation environments, and particularly applicable to smart cards and wireless devices.
