Consider the Shamir Secret Sharing scheme based on polynomial interpolation.
In this scheme, every part has the same right: one piece of information of same value as the other ones.
The idea is to adapt this scheme in following way:
Suppose that we want to share a secret among politicians and generals. The secret can only be retrieved if 3 elements are united and if in that group at least one is a politician and at least one is a general.
How can we do that? It is not clear to me what to do. Thanks in advance.
