Survey of Performance Comparison of DES, 3DES and AES Algorithms

Today cryptography allows people to carry over the confidence found in the physical world to the electronic world, thus allowing people to do business electronically without worries of deceit and deception. Every day hundreds of thousands of people interact electronically, whether it is through?e-mail,?e-commerce (business conducted over the Internet), ATM machines, or cellular phones. The perpetual increase of information transmitted electronically has lead to an increased reliance on cryptography. In this paper of survey about DES, 3DES and AES, DES uses 56-bit key length nowhere DES algorithm can be cracked but the only way is by brute force technique, where it takes around 400 days to decrypt at a rate of 2-billion keys per sec. 3DES uses 112-bits by brute force it takes 800 days to decrypt the message at the same rate. But when it come to AES it uses 256-bit key length even the brute force fails because it takes days to decrypt at the same rate. So AES is the best-known encryption standard.
