%description
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.

More formally, in a secret sharing scheme there is one dealer and n players.
The dealer gives a secret to the players, but only when specific conditions are
fulfilled. The dealer accomplishes this by giving each player a share in such a
way that any group of t (for threshold) or more players can together
reconstruct the secret but no group of less than t players can. Such a system
is called a (t,n)-threshold scheme.
