ABSTRACT:
Authentication is provided for secure devices with limited cryptography, particularly for devices which do not have the capability to do public-key cryptography and generate random numbers. An initialization process is disclosed for limited-power Devices which are unable to perform public-key cryptography and generate random-numbers, as well as for full-power Devices which have the capability to do public-key cryptography and generate random numbers. A Challenge-Response procedure is also disclosed for ensuring the secure state of a device.
