What is a probabilistic mode of operation of a block cipher?
Monday, 05 August 2024 by Emmanuel Udofia
In the field of cybersecurity, particularly within the domain of classical cryptography, the concept of "probabilistic mode of operation" pertains to specific methods employed for utilizing block ciphers to ensure both confidentiality and security. These modes of operation are integral to enhancing the security of block ciphers, especially when encrypting data that exceeds the block
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
