Abstract
A multisignature scheme for implementing safe delivery rule in group communication systems (MSGC) was recently proposed by Rahul and Hansdah. In this paper we show that the MSGC scheme is insecure against forgery attack and signature integrity attack. We propose an improved scheme that resists the weaknesses of MSGC scheme.
The research was supported in part by the Ministry of Communications and Information Technology, Govt. of India, under the grant no. 12(35)/05-IRSD:18/Jan/2005.
