A particular cipher is implemented by combining the ASCII representation of plaintext characters with pseudorandom bytes (eight-bit binary strings of 1s and 0s) using the XOR function. (i.e,, C = P XOR Key). This process can be expanded to double-XOR or even triple-XOR (i.e., C = P XOR K1 XOR K2). Assume that the two pseudorandom bytes are 10110101 (K1) and 01110010 (K2) and the double-XOR is used,.
a. What is the ciphertext (in binary form) generated by the encryption of the character T (Please show your work.)
b. What is the plaintext for the ciphertext 10000001? (Please show your work.)
