## Main Question or Discussion Point

I'm trying to understand the proof that the OTP is a perfect cipher.

I tried to understand the proof shown in http://web.mit.edu/6.857/OldStuff/Fall97/lectures/lecture2.pdf but I don't understand the part C = y and K = (x XOR y).

Could someone assist me in understanding the proof?

Thanks!
