Abstract
A method, suitable for content delivery, is described of communicating a value originating at a first node which forms a part of a first entity, to a third node, which first and second node are separated by a second node which is arranged to generate a key distribution scheme. The third node is arranged to receive keys distributed via the key distribution scheme. The method comprises encrypting the value at the first node using a number N generated by the first entity, and a random number r i generated by the third entity, and where r i and N do not have a common divisor, N has large prime factors p and q, and the second entity is in receipt of N but is not in receipt of p and q. The encrypted value is transmitted from the first node through the second node to the third node.
