Given that I have a secret which I want to split into 2 parts (n=2) and require 2 parts to restore it (k=2), does it still make sense to use Shamir's Scheme or would a trivial scheme with XOR (generate a random string, same long as the secret, XOR those, random string and the XOR result become shares) be just as secure? Are there any benefits in using Shamir's Scheme in such case?
In general, what would be the recommended sharing scheme for this use case?
