In cryptography, the order of the letters in a message is rearranged by __________
A. transpositional ciphers
B. substitution ciphers
C. both transpositional ciphers and substitution ciphers
D. quadratic ciphers
Answer:A
In cryptography, the order of the letters in a message is rearranged by __________
A. transpositional ciphers B. substitution ciphers C. both transpositional ciphers and substitution ciphers D. quadratic ciphers
Explanation: In transposition ciphers, the order of letters in a plaintext message is shuffled using a pre-defined method. Some of such ciphers are Rail fence cipher and Columnar transposition.
