Abstract
A rapid authorization system (22) for subscriber programming authorization with high levels of security can include entitlement management messages (23) that direct fluctuation of an existing package with a communication structure that may involve a primary service directive indicator (3) that is altered, transformed, or fluctuated by a secondary service directive indicator (4) or more. Terse, high entropy directives and entitlement management messages can be transmitted and a multi-channel broadcast programming fluctuation processor (9) at a multichannel broadcast receiver (8) can act to achieve the proper authorization. A conditional access system can be provided through existing, even one-way or SSL, communication pathways with high levels of security. Large subscriber base a la carte options can be provided with rapid authorization that may include nonce programming collective storage (26) for use with a fluctuation entitlement management message transmission.
