comment Addition with Shamir secret sharing
Thanks for the answer! So, just to clarify, you are saying my steps are valid for a multiplication scenario like: z = xy, not an addition one, z = x + y, correct?

Ok, last question, is it ok that the original seed is small or is that somehow related to p and q? In other words, would a larger seed value also make a difference.

Ok, so how would I increase the period?

Why double? The Rabin function can only return an integer.

comment Why is triple-DES using three different keys vulnerable to a meet-in-the-middle-attack?
"With three keys, one half has (k1,k2) and the other k3. Attacking the first half costs 2^114 operations, attacking the second half costs 2^56 operations. For a total of ~2^114 operations." How is this 2^114 operations? Wouldn't it be 2^114 (k1, k2) and 2^56 (k3) for a total of 2^170? Or, do you only count it as 2^114 since K3 and (k1, k2) can be calculated in parallel?
