A novel approach for the cryptographic keys management in the broadcasting scenario with a conditional access control is proposed. It employs the reconfiguration concept, and it is based on a collection of the underlying structures - at each instant of time a structure from the collection is employed for updating the session key so that the communication overhead of updating is minimized. A receiver has a fixed set of cryptographic keys and in a general case, each of these keys plays a different role determined by the employed underlying structure.
