MDS3C: Modified digital signature scheme for secure communication

Abstract

When it comes to security no one can be trusted, there may be situations, when sender’s and receiver’s authentication is required. Digital signature is used to provide the authentication to assure receiver about the message and its sender. Digital signature is an authentication mechanism which generates a unique code with the message, now this attached code (i.e., signature) is responsible for the validation of sender and message. As all know that digital signature provides authentication, message integrity, and non-repudiation services, but does not provide the confidentiality of data as well as signature which is most important during data transfer. This paper proposed a modified digital signature scheme for secure communication. This work includes the concept of public key encryption for secrecy of data. This work will reduce the well-known drawbacks of digital signature scheme. The aim of this technique is to provide the secure communication that includes the security for the data, private key, and digital signature.
