摘要： 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.

摘要： 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.

摘要： 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.
