The Electronic Codebook (ECB) mode of operation is one of the simplest and most straightforward modes for applying a block cipher to encrypt data. Understanding how ECB works and recognizing its inherent security drawbacks is crucial for anyone involved in cybersecurity, particularly in the context of classical cryptography fundamentals and the application of block ciphers.
What are the main differences between deterministic and probabilistic modes of operation for block ciphers, and why is this distinction important?

Block ciphers are a fundamental component of modern cryptographic systems, providing a mechanism to encrypt fixed-size blocks of data. However, to securely encrypt messages of arbitrary length, block ciphers must be used in conjunction with a mode of operation. Modes of operation define how block ciphers can be applied to data sequences that exceed the
