Abstract: Trust between entities participating in an upgrade or enablement/disablement process is established and, to facilitate this remotely and securely, a highly tamper resistant point of trust in the system that is being produced is used. This point of trust enables a more efficient distribution system to be used. Through either a provisioning process or at later stages, i.e. subsequent to installation, manufacture, assembly, sale, etc.; the point of trust embodied as a feature controller on the device or system being modified is given a feature set (or updated feature set) that, when validated, is used to enable or disable entire features or to activate portions of the feature.

Abstract translation: 建立参与升级或启用/禁用进程的实体之间的信任，并且为了便于远程和安全地使用正在生产的系统中的高度防篡改的信任点。 这一信任点使得能够使用更有效率的分配系统。 通过供应过程或在稍后的阶段，即在安装，制造，组装，销售等之后; 在被修改的设备或系统上体现为特征控制器的信任点被给予特征集（或更新的特征集），其在被验证时被用于启用或禁用整个特征或激活特征的部分。
