Abstract

We consider the problem of redistributing shares in a secret sharing scheme in such a way that shareholders of a scheme with one access structure can transfer information to a new set of shareholders, resulting in a sharing of the old secret among a new access structure. We describe a number of different scenarios and applications within which such a redistribution might be required, give some techniques for conducting a redistribution, and discuss the optimisation of the efficiency of such a process.
