  Article:   A MODIFICATION OF THE TSENG-JAN GROUP SIGNATURE SCHEME.

Authors:  CONSTANTIN POPESCU.
 
       
         
  Abstract:  In this paper we present a modification of the Tseng-Jan group signature scheme [18]. Our scheme appears to be secure in comparation with the Tseng-Jan group signature scheme. The proposed scheme is based on the e-th root problem and the discrete logarithm problem. Keywords: Group signature, identity, membership certificate.
