Embodiment Construction

[0038] refer to figure 1 , reference numeral 10 generally denotes a remote device registration or trusted key injection system. The manufacturer 12 of the device 22 utilizes the services of a separate entity, in this case the external manufacturer 14 , to inject unique and immutable information into the device 22 . The information may be a cryptographic key, a shared secret, or some other data that may be cryptographically bound to an inherently unique attribute of device 22 and is hereinafter referred to as a "key". The step of injecting a key into the device 22 will hereinafter be referred to as "key encryption" or "key injection".

[0039] The manufacturer 12 uses a controller 16, which is a computer system remote from the manufacturer's facility. The controller 16 includes a hardware security module (HSM) 11 . HSM 11 is a protected device used by controller 16 to cryptographically perform secure operations such as encryption, decryption and signing. The HSM 11 may be t...

Abstract

A system and method provided for controlling process of producing products, wherein introducing separation of duties to production process to prohibit over-production. Usually, manufacturer contracts various stages of production process to plural contractors. In general, separation of duties relates to purposefully separate production processes used for silicon chips or other products, to make subcontractors manage or contact terminal product to make the terminal product fully functional, which is accomplished by a mathematical manipulation module for intercepting and transforming the data stream in a product. The mathematical manipulation requires cipher key operable, and the product requires the successful work of mathematical manipulation is operable, and the cipher key is divided into plural parts of sensitive data, which will be added to plural stages of production processes.

Description

technical field [0001] The present invention generally relates to producing products with sensitive data therein. Background technique [0002] Devices participating in a cryptographically secure communication system will typically have some sort of unique and immutable information injected into the device at the time of manufacture. This information may be a cryptographic key, a shared secret, or some other data that may be cryptographically bound to an inherently unique property of the device. Such information can generally be referred to as a "key", and the injection of information can generally be referred to as "encrypting a key (key)" or "key injection" to a device. [0003] The purpose of injecting keys is to ensure that the device is accepted as a trusted participant of the secure communication system at some point in the future after the device is allocated. However, manufacturers of devices will often wish to ensure that the devices were legally produced and ther...
