Comment on Oops. Cryptographers cancel election results after losing decryption key.
logi@piefed.world 1 day agoThat's actually bit true. See the other comment about Shamir Secret Sharing. Very clever stuff where you can split a key in m parts and require n

But with SSS and m=3, n can only be 1, 2 or 3. If n=2 there is a possibility for a conspiracy of 2 and a redundancy of 1, if n=3 then all three have to agree, but there is no redundancy, which was the case here.

Right. Re-reading your comment, I agree. n=3 is too small, even with SSS. BUT without it, 3 was too big in this case. So yey SSS!
