Between linear and differential cryptanalysis which is efficient for breaking DES?
The Data Encryption Standard (DES) is a symmetric-key algorithm for the encryption of digital data. Developed in the 1970s, DES became a widely adopted encryption standard. However, with the advancement of computational power and cryptanalytic techniques, DES has been subject to various forms of cryptanalysis, among which linear and differential cryptanalysis are particularly notable.

Can DES be broken by differential cryptanalysis?
Differential cryptanalysis is a form of cryptanalysis applicable primarily to block ciphers, which involves analyzing the effect of particular differences in input pairs on the differences at the output. This method was introduced by Eli Biham and Adi Shamir in the late 1980s and has since become a fundamental tool in the cryptanalyst's toolkit. The
Is differential cryptanalysis more efficient than linear cryptanalysis in breaking DES cryptosystem?
Differential cryptanalysis and linear cryptanalysis are two commonly used techniques in the field of cryptanalysis to break cryptographic systems. In the case of breaking the DES (Data Encryption Standard) cryptosystem, differential cryptanalysis is generally considered to be more efficient than linear cryptanalysis. Let’s consider a detailed explanation of the reasons behind this assertion. Differential cryptanalysis
Explain the significance of the key size and the number of rounds in AES, and how they impact the level of security provided by the algorithm.
The Advanced Encryption Standard (AES) is a widely-used symmetric block cipher that provides secure encryption for various applications. The security of AES is influenced by two key factors: the key size and the number of rounds. The key size in AES refers to the length of the secret key used for encryption and decryption. AES
