Shamir's Secret Sharing Scheme (SSSS) is an implementation of a
|
|
threshold scheme for sharing a secret between third parties, and
|
|
requiring a threshold of those parties to collaborate to reveal the
|
|
secret.
|
|
|
|
Taken from the Wikipedia article about Secret Sharing:
|
|
|
|
In cryptography, a secret sharing scheme is a method for
|
|
distributing a secret amongst a group of participants, each of
|
|
which is allocated a share of the secret. The secret can only
|
|
be reconstructed when the shares are combined together;
|
|
individual shares are of no use on their own.
|
|
|
|
Shamir's scheme is provable secure: in a (t,n) scheme one can prove
|
|
that it makes no difference whether an attacker has t-1 valid shares
|
|
at his disposal or none at all; as long as he has less than t shares,
|
|
there is no better option than guessing to find out the secret.
