Implementation of Digital Signature in Automatic Office System
Cuihua Li · Jisuanji gongcheng · 2005
A novel digital signature method is implemented in the automatic office system.In this method,MD5 information digest algorithm has been adopted to extract the print of documents and RSA public key algorithm has been adopted to produce digital signature on document print.These two algorithms can protect documents from being tampered and document receiver can make sure of the author of the document he received.In order to make sure the key’s origin and security,the paper comes up with a subsystem called the key build and management system to produce keys for all valid users.The running test proves that the method has an ideal performance in measuring of executing time and memory space.
