Description: Function-based encryption is a method of encryption that applies mathematical functions and algorithms to data to ensure its confidentiality and authenticity. This approach is based on the idea of transforming the original information, known as plaintext, into an unreadable format, called ciphertext, by applying an encryption function. The main characteristics of this type of encryption include reversibility, where the ciphertext can be converted back to plaintext using an inverse function, and security, which depends on the complexity of the function used and the encryption key. This method is fundamental in protecting sensitive data, as it allows information to be transmitted or stored securely, preventing unauthorized access. Additionally, function-based encryption is versatile and is used in various applications, from protecting communications to securing data in various environments and systems. Its relevance in today’s digital world is undeniable, given the rise of cyber threats and the need to safeguard the privacy of personal and business information.
