Abstract: In order to verify the authenticity of a product associated with a host device, the product contains, in segments of a non-volatile memory, several different functions stored in ciphered fashion. The host device sends a control signal for selecting and activating one of those ciphered functions. The product then deciphers and executes the function. The result of the function execution is then enciphered and communicated back to host device when a decision on product authenticity is made.

Abstract: A circuit includes a first processing unit and a second identical processing unit. A first communication bus passes encrypted data between one of a plurality of functions and one or both of the first and second processing units. A selection circuit determines whether the encrypted bus is coupled to the first processing unit, the second processing unit, or both of the first and second processing units.

Abstract: The authenticity of a product associated with a host device is verified through a process. The product contains, in segments of a non-volatile memory, several different functions stored in ciphered fashion. The process involves, in a first phase, the sending by the host device of a control signal for executing a function, with the product functioning to decipher the function and store the unciphered function in the non-volatile memory. The process further involves, in a second phase, the sending by the host device of a control signal for causing execution of the deciphered function, with the product functioning to execute the function and send a result of this execution back to the host device. The host device evaluates the received result to verify product authenticity.
Abstract translation: 通过一个过程验证与主机设备相关联的产品的真实性。 该产品在非易失性存储器的段中包含以加密方式存储的若干不同功能。 该过程在第一阶段涉及由主机设备发送用于执行功能的控制信号，其中产品用于解密功能并将未加密功能存储在非易失性存储器中。 该过程还包括在第二阶段中由主机设备发送用于执行解密功能的控制信号，其中产品用于执行功能并将该执行的结果发送回主机设备。 主机设备评估接收到的结果以验证产品的真实性。
