Abstract:
One of n≥2 servers, connectable via a network, implements a cryptographic protocol using a secret key K which is shared between the n servers, and includes first and second server compartments. The first is connectable to the network, adapted to implement the cryptographic protocol, and stores a current key share of the secret key K. The second is inaccessible from the network in the operation of the server, stores a set of master keys, and is adapted, for each of successive time periods, to unilaterally generate a new key share of the secret key K and to supply it to the first as the current key share for that time period. The new key share includes a random share of a predetermined value p which is shared between the n servers, and the random share includes a function of the set of master keys.

Claim (Index 5):
The server as claimed in  claim 4  wherein the second server compartment stores the current key share for each time period of the successive time periods and the new key share for each time period comprises a sum of the current key share for an immediately previous time period and the random share \u03b4 i .
