Question

What name is given to an encryption cipher that is a product cipher with a 56-bit key consisting of 16 iterations of substitution and transformation?

A. Data Encryption Standard (DES)
B. Keyword mixed alphabet cipher
C. One-time pad cipher
D. Substitution cipher

Answer 1

Data Encryption Standard (DES) is the name given to the encryption cipher that meets the criteria described in the question. the correct answer is A.

Step-by-step explanation:

The name given to an encryption cipher that is a product cipher with a 56-bit key consisting of 16 iterations of substitution and transformation is Data Encryption Standard (DES). DES is a symmetric key algorithm that was widely used in the past for secure data transmission and storage. It uses both substitution and transposition techniques to encrypt the plaintext.

described is the Data Encryption Standard (DES), which used a 56-bit key and performed 16 rounds of complex substitutions and transformations.

The name given to an encryption cipher that is a product cipher with a 56-bit key consisting of 16 iterations of substitution and transformation is the Data Encryption Standard (DES). This encryption method was once widely used in various secure communications before being succeeded by more secure algorithms. The DES encryption process involves the use of a 56-bit key and executes a series of complex transformations and substitutions on the plaintext, through 16 rounds or iterations, to produce the ciphertext.
