Abstract
In accordance with some embodiments, multiple blind debug passwords are provided. Each of a plurality of interested entities may have its own password and each password may unlock a specific set of features offered by an integrated circuit. In some embodiments each entity does not know the other passwords of the other entities. Potentially interested entities include an integrated circuit end customer, the original equipment manufacturer, the entity that provided the features to the integrated circuit and a conditional access provider. All debug features may be controlled solely via access to the debug tiers which are accessed by multiple debug passwords. Lower tier passwords are required in order to access higher tiers. Debug features may be separated into multiple tiers with more intrusive access requiring multiple debug passwords in order to gain access.
