BTW K of N cryptography is well known as Shamir’s Secret Sharing.

- mprovost 6y agoAnd in TFA
- hyko 6y agoEven worse, what if one or more children lose their bits and can’t provide their piece?

- acid__ 6y agoHave each child make horcuxes of their horcrux :)
- booleandilemma 6y agoThen what happens if one child who knows they won’t get anything, refuses to provide their piece? Don’t give that child a piece in the first place!
- saurik 6y agoNot all K of N schemes are "secret sharing" (the most well known ones aren't), though I agree that for this will case you probably want a secret sharing algorithm and not say, an erasure code (as you want the property of zero information transfer); however, certainly not all secret sharing algorithms are Shamir's specific secret sharing algorithm.
