Distributed digital signature system on the network key distribution,certification,accreditation plays an important role.Based on RSA′s multi-E1Gama1 type digital signature scheme in an orderly manner,the same documents were signed by the people involved,if an attacker from the user′s public key solves of the private key,that is equivalent to solving the discrete logarithm question,the same attacker to open each and every signer′s public key to send the random number is also in solving the discrete logarithm problem to solve.Signature program makes structural safety of large numbers,at the same time,satisfies the decomposition and the discrete logarithm problem complex.The use of RSA encryption on the message avoids the use of explicit message sent, and ensures the confidentiality of information.
