Block and Stream Ciphers Question.

Let K = 1011 0011 1010 1000

define Ki for i {1, 2, 3, 4} to be the ith block of four bits in K, e.g., K3= 1010.

Find the value of x = 0101 when XORd with each of the Ki.

Your answer should consist of four bitstream, one for each Ki XORd with x.

Please show all steps of how to work out the answers.
