Block cipher modes
Explain why some block cipher modes of the operation use encryption whereas the others use both the encryption and the decryption?
Expert
Some block cipher modes of the operation use the encryption since input is set to some initialization vector and leftmost bits of output of encryption function are XORed along with the first segment of the plain text p1 in order to generate the first unit of the cipher text C1 and it is sent. However in the decryption, cipher text is XORed along with the output of encryption function in order to generate the plain text.
