We propose minimalist new hardware additions to a microprocessor chip that protect cryptographic keys in portable computing devices which are used in the field but owned by a central authority. Our authority-mode architecture has trust rooted in two critical secrets: a Device Root Key and a Storage Root Hash, initialized in the device by the trusted authority. Our architecture protects trusted software, bound to the device, which can use the root secrets to protect other sensitive information… CONTINUE READING
