The Rijndael algorithm is a complex cryptographic algorithm developed by Belgian cryptographers Joan Daemen and Vincent Rijmen. It was selected by NIST in 2000 as the basis for AES, the Advanced Encryption Standard, and is used in global communications for secure transmission of data. The algorithm is a block cipher and can use keys of […]
Data encryption is crucial for cyber security to protect against espionage. Encryption algorithms use mathematical functions and unique keys to convert plain text into unrecognizable characters. Strong encryption standards use complex functions and large keys, such as Blowfish and RSA. One of the fundamental roles of cyber security is to protect data from malicious espionage […]
Algorithmic complexity is the shortest and most efficient program capable of producing a binary string. It plays an important role in computational complexity theory and algorithmic information theory. Objects and properties can also have algorithmic complexity, and complexity classes determine the relative difficulty of computing solutions to mathematical and logical problems. The principle of minimum […]
Secure hashing algorithms (SHA) organize digital data into smaller packages and are used to authenticate messages. They are important for protecting proprietary methods and sensitive data. SHAs are implemented through hardware or software, and the US government has standardized at least six algorithms. The SHA-2 family is more robust than SHA-1 and a new algorithm, […]
Algorithmic trading uses mathematical models to make decisions and trades in financial markets. It is most widely used by large institutional investors due to its advantages, including the ability to break up large trades and the speed of decision-making. Trading algorithms have a longer history and are used to recognize patterns in real-time market data. […]
