Han Qing-min · Journal of Xiangnan University · 2007
A digital signature system have been designed and applied.It gets message digest of the transmitting file by MD5 algorithm,and then sending side uses RSA algorithm to encrypt the message digest by private key.When receiving side received the file and encrypted digest,a certification can be got from contrasting the recalculated digest and the digest disrupted by public key.The system can meet the operational requirements.
