Abstract: A method of pairing between a first host device and a first peripheral device includes entering by a user of the first host device a verification value, as well as comparing, by the first peripheral device, between the verification value and a first secret value stored in a memory of the first peripheral device. When the verification corresponds to the first secret value, the method of pairing further includes calculating and storing a first pairing key by the first host device and the first peripheral device to perform the pairing.

Abstract: A first integrated circuit chip is assembled to a second integrated circuit chip with a back-to-back surface relationship. The back surfaces of the integrated circuit chips are attached to each other using one or more of an adhesive, solder or molecular bonding. The back surface of at least one the integrated circuit chips is processed to include at least one of a trench, a cavity or a saw cut.

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 method of authenticating a slave device. The method includes initializing, by a host device, a charge retention circuit of the slave device, and receiving, by the host device, an indication of a discharge time of the charge retention circuit. The host device authenticates the slave device based on the received indication of the discharge time of the charge retention device.

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.
