Abstract

A delivery system for managing security keys uses three key pairs to establish, register, move, and revoke rights in a device (705) used to view protected matter. The first and second key pairs cooperate to establish a secure certificate (740) containing a device public and private key, and the pairs of keys are manipulated to install the appropriate keys in the device and associated authentication server without ever exposing the keys. Thereafter, in the event of a need to authorize a new device to view content associated with a prior, authorized device, the key pairs are used to revoke the rights of an old device and establish identical viewing rights in the new device.
