Abstract: System and techniques for secure unlock to access debug hardware are described herein. A cryptographic key may be received at a hardware debug access port of a device. A digest may be computed from the cryptographic key at an unlock unit of the device. A fuse value may be received from a non-volatile read-only storage on the device. The digest and the fuse value may be compared to determine whether they are the same. A pass-fail pulse may be provided that indicates the result of the comparing.

Abstract: An integrated circuit is provisioned after the integrated circuit has been sold and integrated into a customer's product. During provisioning, the integrated circuit is booted in a secure manner using a security value, such as a cryptographic key, owned by a manufacturer of the integrated circuit, or by a purchaser of the integrated circuit, to establish a secure communications channel with a provisioning server. Once the secure communications channel is established, the integrated circuit can be provisioned with a security value that is owned by the purchaser of the integrated circuit and the manufacturer's security value is disabled.
