A DEVICE AND A METHOD FOR CONTROLLING USE OF A CRYPTOGRAPHIC KEY

Abstract: a computer-implemented method for controlling use of a first cryptographic key in a device, wherein the device stores first information specifying the configuration of the device. the method comprising: obtaining the first cryptographic key and second information specifying a device configuration for which use of the first cryptographic key is permitted; comparing the second information with the first information to determine whether the first information is consistent with the second information; and in response to determining that the first information is consistent with the second information, performing a first operation using the first cryptographic key on the device.
