Question
In which cipher mode, all cipher blocks will be chained so that if one is modified the cipher text cannot be decrypted correctly?(A) Electronic Code Book(B) Cipher Block Chaining(C) Cipher Feedback Mode(D) Counter Mode
Step 1
In cryptography, chaining refers to the process where each block of plaintext is XORed with the previous ciphertext block before being encrypted. This means that each block of ciphertext depends not only on the current plaintext block but also all the previous Show more…
