Online/Offline Signature Based on Bilinear Pairings
Cao Jia-li · Journal of Guangdong University of Technology · 2007
Online/Offline signatures are used in a particular scenario where the signer must respond quickly once the message to be signed is presented.This paper presents two online/offline signature schemes from bilinear pairings.Without the random oracle assumption,these two schemes are proved secure.Furthermore,without increasing the overall computation,the new schemes' online computation requires only about one fourth of that of the old schemes
