Secure Message Transferring System Using Arbitrated Digital Signature and RSA Algorithm

Abstract

Today, security is an important thing that needs to transport data from location to another safely. Therefore, many models and systems are looking for an ideal method to provide a secure environment for better of the secure communication. Cryptography accepts the challenge and plays the main role of the modern secure communication. The purpose of this system is to develop RSA algorithm with arbitrated digital signature for message security. In this system, Arbitrated Digital Signature handles several forms of dispute between two parties .And the message authentication protects between two parties who exchange message from Arbiter. So, both two parties cannot directly check whose signature. And then, this purposed algorithm was developed based on the asymmetric algorithm whereas the length of the key and digital signature is considered.
