If the secret sharing schemes can adapt to the change of the access structure, then we call them the dynamic secret sharing schemes. If these schemes can not only adapt to the change of the access structure, but also to the change of the shared secrets, we call them fully dynamic secret sharing schemes.
In this paper we establish a formal setting to study secret sharing schemes of this kind. The security of the schemes presented is unconditional, since they are ...
