In DES a change to one bit of plaintext or key results in do

In DES, a change to one bit of plaintext or key results in dozens of bits of ciphertext changing. What effect is this called? use the student id J00386388 then your plaintext is 00386388386388 (in hex) and your key is 00386388386388 (in hex).

Solution
