|1. (WO2018125325) SECURE DEVICE STATE APPARATUS AND METHOD AND LIFECYCLE MANAGEMENT|
|Title:||SECURE DEVICE STATE APPARATUS AND METHOD AND LIFECYCLE MANAGEMENT|
A semiconductor chip device include device state fuses that may be used to configure various device states and corresponding security levels for the semiconductor chip device as it transitions from wafer manufacturing to provisioned device. The device states and security levels prevent the semiconductor chip device from being accessed and exploited, for example, during manufacturing testing. A secure boot flow process for a semiconductor chip device over its lifecycle is also disclosed. The secure boot flow may start at the wafer manufacturing stage and continue on through the insertion of keys and firmware.
