Question

What is the effective key length in triple-DES? a. 56 bits b. 112 bits c. 168 bits d. 192 bits

Answer 1

Answer:it is 192 bits

Explanation:128 bits. It uses DES in the round function and accepts three different key sizes, namely 128, 192, and 256 bits.

Answer 2

The effective key length in triple-DES is 168 bits.

Answer: Option(C) 168 bits.

Explanation:

The Triple-DES states the use of three separate DES keys. It has 168 bits of total key length. Even this key security falls towards 112 bits.

This is a sort of computerized cryptography where the block cipher algorithms are utilized three times to every single data block. Thus, the triple-DES key size is 168 bits.
