An Approach to Security Using Rijndael Algorithm

The existing system consisted of files with literally no file security. The main issue of Reading or tapping data is secrecy and confidentiality. Confidentiality has always played an important role in diplomatic and military matters. Often Information must be stored or transferred from one place to another without being exposed to an opponent or enemy. The main aim of presenting this paper is to encrypt a java file using Rijndael Algorithm. The first aspect that has to be considered in our paper is file security and the need for file security. Key management is also related to Confidentiality. This deals with generating, distributing and storing keys .File security must be implemented so as to eliminate the problems like unauthorized access, execution of commands illicitly, destructive behavior and confidentiality reaches. The values of Keywords Bytes, Cipher, state, finite field Addition, multiplication. 1. INTRODUCTION Standards like Rijndael was to be implemented due to the following factors against which several security measures had to be taken up like. Reading or tapping data, Manipulating and modifying data and Illegal use of files, Corrosion of data files, Distortion of data transmission and Disturbance of the operation of equipment or systems. Also Computer files and networks must be protected against intruders and Unauthorized. That includes File Security, Cryptography and Private-Key-Encryption, Key Management.
