Python and Crypto: Learning With Errors and Ring Learning With Errors

[aleph]

solid explanations for people with some background but not a ton: not too simplistic not too complicated.

Hi professor Buchanan, I have a question: the LWE encryption schemes are non deterministic right? because the final decrypted results are approximations to the real results. What is the accuracy of these results? Could we say that they are 95% accurate or something similar?

Your videos are amazing!!

@15:10 I'm not familiar with the RLW-KEX protocol, is the np.floor(sA, xN_1)[1]) supposed to be np.floor(bA, xN_1)[1])? Same thing with sB => bB? It just doesn't seem to obviously follow from the preceding explanation of RLW-KEX.

Thanks for making this video. I have a question about RLWE, why did you set x^n-1 to be like this xN_1 = [1] + [0] * (n-1) + [1]? Please, can you elaborate on this? I appreciate your time. Thanks,
