Designing E-signature-based algorithm ElGamal for authentication of electronic documents for E-government of Vietnam


Chan Kong Tan

In this paper we introduced a new digital signature which works very well for such applications which have low file size for sending. The new hash function generates dynamic and smaller size of bits which depends on each bytes of message. A simple mechanism for hashing the message and encryption is one of advantages of suggestive algorithms. Testing new algorithms showed that its hashed file size is 4% of the original file in messages with size lower than 1600 bytes. This algorithm can be used in applications which have low file size for sending and want simple and fast algorithms for generating digital signature.
