A multi-group digital signature solution based on the ACJT group signature
Lin Li-zhong · 2008
Digital signature has been used widely in people's daily life nowadays.Different applications of the digital signature may add extra requirements.All these requirements also push this technology into more and more applications,not just the original usage as the digital reproduction of the handwriting signature.Special digital signature technologies also come up for multi-purpose applications.This paper presents an improved solution based on the group signature solution proposed by G.Ateniese and G.Tsudik(also called ACJT solution).The construction process of this improved solution utilizes a more efficiency knowledge-signature protocal.Also the signature security of this solution has been fully analisized by using the random language model.
