- 2. Advanced Encryption Standard (AES) popular and widely adopted symmetric encryption Six time faster than triple DES Features: 1.) Symmetric key symmetric block cipher 2.)128-bit data, 128/192/256-bit keys 3.)Stronger and faster than Triple-DES 4.)Provide full specification and design details 5.)Software implementable in C and Java Introduction
- 3. Encryption & Decryption Encryption Process Byte Substitution Shift rows Mix columns Add Round key Decryption Process Add round key Mix columns Shift rows Byte substitution
- 4. AES Operations An iterative rather than Feistel cipher. Based on ‘substitution– permutation network’. AES uses 10 rounds for 128- bit keys, 12 rounds for 192- bit keys and 14 rounds for 256-bit keys. series of linked operations: replacing inputs by specific outputs (substitutions). involve shuffling bits around (permutations).

- 10. Nowadays, the networks have gone global and information has taken the digital form of bits and bytes. Critical information now gets stored, processed and transmitted in digital form on computer systems and open communication channels. Since information plays such a vital role, adversaries are targeting the computer systems and open communication channels to either steal the sensitive information or to disrupt the critical information system. Modern cryptography provides a robust set of techniques to ensure that the malevolent intentions of the adversary are thwarted while ensuring the legitimate users get access to information. Here in this chapter, we will discuss the benefits that we draw from cryptography, its limitations, as well as the future of cryptography. Conclusion
