    Abstract: A processor is provided that binds itself to a circuit such that the processor cannot be subsequently reused in other circuits. On a first startup of the processor, a memory segment of an external volatile memory device is read to obtain information prior to initialization of the memory segment. An original/initial identifier may be generated from the information read from the memory segment. The original/initial identifier may then be stored in a non-volatile storage of the processor. On subsequent startups of the processor, it verifies that the processor is still coupled to the same external volatile memory device by using the stored identifier. For instance, on a subsequent startup, the processor again reads the same memory segment of the external memory device and generates a new identifier. If the identifier matches the previously stored identifier, then the processor may continue its operations; otherwise the processor is disabled/halted.

    Abstract translation: 提供了一种处理器,其将其自身绑定到电路,使得处理器不能随后在其他电路中重复使用。 在处理器的第一启动时,读取外部易失性存储器件的存储器段,以在存储器段的初始化之前获得信息。 可以从从存储器段读取的信息生成原始/初始标识符。 原始/初始标识符然后可以存储在处理器的非易失性存储器中。 在处理器的后续启动时,它通过使用存储的标识来验证处理器仍然耦合到相同的外部易失性存储器设备。 例如,在随后的启动中,处理器再次读取外部存储器件的相同存储器段并产生新的标识符。 如果标识符与先前存储的标识符匹配,则处理器可以继续其操作; 否则处理器被禁用/停止。

    Abstract: A system is provided for inside-to-outside or outside-to-inside cryptographic coding that facilitates product authentication along a distribution channel. An association of authenticated, secured codes is generated between inner items (e.g., pharmaceutical doses such as pills, capsules, tablets) and outer items (e.g., packaging containing inner items). For instance, an inner code associated with a first item is used to generate (at least partially) an outer code associated with a second item that contains one or more first items. This process may be repeated multiple times with codes for outer items being a function of codes for inner items. The sequence of items may be authenticated by the dependent relationship between their codes.

    Abstract translation: 提供了一种用于内部到外部或外部到内部的加密编码的系统,其有助于沿着分发渠道的产品认证。 在内部物品(例如药物剂量,例如丸剂,胶囊,片剂)和外部物品(例如,包含内部物品的包装)之间产生经认证的安全代码的关联。 例如,与第一项目相关联的内部代码被用于生成(至少部分地)与包含一个或多个第一项目的第二项目相关联的外部代码。 该过程可以重复多次,外部项目的代码是内部项目的代码的函数。 项目的顺序可以通过其代码之间的依赖关系进行认证。
