Khaled Salah Mohamed - New Frontiers in Cryptography: Quantum, Blockchain, Lightweight, Chaotic and DNA

Stream ciphers, block ciphers, public key algorithms and digital signatures.

Quantum cryptography: Quantum cryptography uses physics to develop a cryptosystem completely secure against being compromised without the knowledge of the sender or the receiver of the messages.

Blockchain cryptography: Blockchain is a distributed database that allows direct transactions between two parties without the need for an authoritative mediator. Blockchain cryptography is a way to encapsulate transactions in the form of blocks where blocks are linked through the cryptographic hash, hence forming a chain of secured blocks.

Lightweight cryptography: Lightweight cryptography works between the trade-offs of security, cost, and performance and is focused at devices and systems on edge.

Chaotic cryptography: Many strong ciphers have been applied widely, such as DES, AES and RSA. But most of them cannot be directly used to encrypt real-time embedded systems because their encryption speed is not fast enough and they are computationally intensive. So, chaotic cryptography is suitable for real-time embedded systems in terms of performance, area and power efficiency.

DNA cryptography: DNA cryptography is a promising and rapid emerging field in data security. DNA cryptography may bring forward a new hope for unbreakable algorithms. DNA cryptology combines cryptology and modern biotechnology.

Steganography: Steganography is the art of hiding the existence of a message between sender and intended recipient. It hides secret messages in various types of files such as text, images, audio and video.

Watermarking: Watermarking is embedding some information within a digital media so that the digital media looks unchanged. This is useful for copy protection.
