New Multisignature Scheme Based on Bilinear Pairings

摘要

Two digital multisignature schemes based on bilinear pairings were proposed. One of them is the sequential digital multisignature, and the other is the broadcasting digital multisignature. The scheme has the same security as JI and LI's multisignature scheme, but the new scheme has the lower computation. So the new scheme is the multisignature which has high security and low computation. It has the theory meaning and extensive application under the condition of SmartCard, etc.
