Encryption Technique for Secure Password Authentication Scheme at Application Layer

Abstract

Password security is the main issue in today’s trends. Everything is based on the internet. For securing our data, files etc. we need password .Password should be secure and safe from third party and it must be safe from shoulder suffering attack, for that purpose we design an authentication scheme at application layer. To secure our password we use AES Encryption technique. This Paper shows the design of effective security issue for password by AES algorithm for encryption and decryption. It is based on AES Key Expansion in which the encryption process is a bit wise exclusive or operation of a set of strings and numbers with the 128 bit key which changes for every set of strings.
