The repo is about simple implementation of various algorithms and techniques used in cryptography, namely Simplified DES, Simplified AES, RSA, Caesar Cipher, Monoalphabetic Cipher. A client-server ...

Abstract: This paper proposes a simplified AES algorithm resistant to zero-value DPA (differential power analysis) attack and its VLSI implementation. This paper makes some improvements to the ...

A client-server application with confidential message exchange to provide authentication, integrity and key sharing among both the client and server with the help of RSA and AES algorithm. A ...

Abstract: The simplified AES (S-AES) algorithm is used in Zigbee and sensor networks as a fast encryption method but it is easy breakable and not secure. Thus it doesn't meet the security requirements ...
