Implementation of Secrete Message Communication in Server/Client Environment Using Splines Based on PKCS

Abstract

This paper presents an approach for a secret message communication among a client–server group. In order to increase security to distribute secret message (key), we introduce splines using these at a specific permutation. We generate the key and distribute this key. This is to maintain confidentiality. Confidentiality can be achieved through changing the key material, known as re-keying every time a new member joins the group or a existing member leaves the group. The new group key is computed guaranteeing the forward and backward secrecy. Whenever there is a membership change, group key must be changed to prevent a new use from reading past communication. In proposed work, we propose how group communication must establish registration of users, entry and exit of a user. The encryption and decryption algorithm is used between the sender and the receiver. In the process, a spline is installed in the server; the server will distribute or communicate the secret messages to client based on one-to-one mapping with the help of splines; message has been encrypted and distributed to respective clients. In the client side, the decryption batch files to be installed for the verification of secret message authentication.
