haha i read this headline and thought to myself "breaking textbook RSA is EXACTLY what I was just learning about in class today" and then I noticed one of the authors is my professor
Then perhaps you could point me in the right direction: where Cb = C (2^(be) mod(n)) (mod n) I assume we are calculating Cb by encrypting the bit-shift and then applying it to C (which is already encrypted). Why do we need that last modulus at the end?
Haha let me get back to you once I finish replicating the paper (not using QQ but a sandbox) which we have to / get to do for hw :)
