Implementation of AES Algorithm in MicroController Using PIC18F452
Journal Title: IOSR Journals (IOSR Journal of Computer Engineering) - Year 2013, Vol 15, Issue 5
Abstract
Security has become an increasingly important feature with the growth of electronic communication which calls for more advanced ways to encrypt the raw data[1]AES-128 is going to be implemented as the encryption algorithm as there are 3 types of AES (AES-128,AES-192,AES-256) but why AES? Because AES is famous for its ciphering strength and its strong defense against any attack for example the brute force attack. Using Brute force attack on AES-128 (smallest key length) is unlikely to be practical in the foreseeable future [3]. According to NIST, "Assuming that one could build a machine that could recover a DES key (DES is an old encryption algorithm which no one uses now in modern days) in a second (i.e.,try 2^55 keys per second), then it would take that machine approximately 149 thousand-billion (149 trillion) years to crack a 128-bit AES key". In this paper AES-128 will be implemented on a microcontroller circuit to give it further security and more speed in both the encryption and decryption of the files.
