Key Concepts

Encryption

Encryption is the process of converting plain text into cipher text using various algorithms, ensuring that sensitive information is protected from unauthorized access. It plays a vital role in securing data by transforming it into a format that is unreadable without the appropriate decryption key, thereby maintaining data confidentiality and integrity.

Stream Cipher

A stream cipher is an encryption method that encrypts data one bit or byte at a time. It is particularly effective for data transmitted as a continuous stream and is commonly used in environments where latency and processing speed are critical. The simplicity and efficiency of stream ciphers make them suitable for real-time applications, though they require careful management of initialization vectors to maintain security.

Block Cipher

A block cipher is an encryption method that divides data into fixed-sized blocks and encrypts each block using a symmetric key. This approach is widely adopted in many cryptographic protocols, providing robust security by processing data in large chunks. Block ciphers are versatile and can be employed in various operational modes to enhance security and performance, making them fundamental in modern cryptographic systems.
