摘要： A system and method for remote device registration, to monitor and meter the injection of keying or other confidential information onto a device, is provided. A producer who utilizes one or more separate manufacturers, operates a remote module that communicates over forward and backward channels with a local module at the manufacturer. Encrypted data transmissions are sent by producer to the manufacturer and are decrypted to obtain sensitive data used in the devices. As data transmissions are decrypted, credits from a credit pool are depleted and can be replenished by the producer through credit instructions. As distribution images are decrypted, usage records are created and eventually concatenated, and sent as usage reports back to the producer, to enable the producer to monitor and meter production at the manufacturer.
摘要翻译：提供了用于远程设备注册的系统和方法，用于监视和计量密钥或其他机密信息到设备上的注入。使用一个或多个单独的制造商的生产商操作远程模块，其通过前向和后向通道与制造商的本地模块进行通信。加密的数据传输由制造商发送给制造商，并被解密以获得在设备中使用的敏感数据。当数据传输被解密时，来自信用卡的信用被用尽，并且可以通过信用指示由生产者补充。随着分发图像被解密，创建使用记录并最终并入，并将其作为使用报告发送回制造商，以使制造商能够监视制造商的生产计量。

摘要： 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.

摘要： A partial revocation list and a system and method for using the partial revocation list for tracking the authenticity of replacement cartridges in a manufactured device to inhibit cloning of the cartridges is provided. A revocation pool is maintained by a manufacturer who chooses a partial revocation list from the revocation pool to store in the memory of the cartridge. The device stores its own revocation list, informs the manufacturer of cartridges which have been used and checks when a new device is installed to ensure a cloned replacement is not being used. The partial revocation list distributes enough revocation information to devices to statistically impair the cartridge yield of a cloning operation.

摘要： A method of generating a key stream for a precomputed state information table. The method comprises initialising a counter and an accumulator with non-zero values; combining state information identified by the counter with the accumulator; swapping state information identified by the counter with state information identified by the accumulator; combining the two pieces of state information; outputting the state information identified by the combination as a byte of the key stream; adding a predetermined number odd number to the counter; and repeating the above steps to produce each byte of the key stream.

摘要： A system and method for controlling a production process for producing a product is provided in which overproduction may be inhibited by introducing a separation of duties within a production process. Typically a producer will contract out the various stages of a production process to multiple contractors. In general, separation of duties involves purposefully separating production stages, for silicon chips or other products, so that the end product has been handled or “touched”, by each subcontractor, in order for the end product to be fully functional.
摘要翻译：提供了一种用于控制生产产品的生产过程的系统和方法，其中可以通过在生产过程中引入任务分离来抑制过量生产。通常，生产者将将生产过程的各个阶段合同到多个承包商。一般来说，职责分工有目的地将生产阶段，硅片或其他产品分开，以便最终产品被每个分包商处理或“触及”，以使最终产品完全起作用。

摘要： The present invention provides an inexpensive, software-based security-retrofit solution to verify the integrity of program code in embedded systems, or accessories, without resorting to expensive hardware changes. All unused memory on an accessory that could be used to store a program code image is filled with random data. A host system also locally stores a copy of the accessory's program image containing the random data. The host system sends the accessory a list of memory addresses or memory ranges on the accessory, which is always different and random in nature. The accessory will then produce a digest using values stored in the memory addresses as inputs to a secure hash function. The host system verifies the integrity of the embedded program code by verifying the resulting digest produced by and returned from the accessory.
摘要翻译：本发明提供了一种廉价的基于软件的安全改进解决方案，用于在不诉诸昂贵的硬件改变的情况下验证嵌入式系统或附件中的程序代码的完整性。可用于存储程序代码图像的附件上的所有未使用的内存都填充有随机数据。主机系统还在本地存储包含随机数据的附件的节目图像的副本。主机系统向附件发送附件上的存储器地址或存储器范围列表，该列表本质上是随机的。然后，附件将使用存储在存储器地址中的值作为安全散列函数的输入来生成摘要。主机系统通过验证由附件生成和返回的结果摘要来验证嵌入式程序代码的完整性。
