SRK Revocation on i.MX 6 Series

 CST: Code Signing Tool, an application running on a build host to generate a CSF and

associated digital signatures.

 DCD: Device Configuration Data, a binary table used by the ROM code to configure the device

at early boot stage.

 HAB: High Assurance Boot, a software library executed in internal ROM on the Freescale

processor at boot time which, among other things, authenticates software in external memory by

verifying digital signatures in accordance with a CSF. This document is strictly limited to

processors running HABv4.

 IVT: Image Vector Table.

 OS: Operating System.

 Accelerator (including hash acceleration) found on some processors.

 SDP: Serial Download Protocol, also called UART/USB Serial Download Mode. This allows

code provisioning through UART or USB during production and development phases.

 SRK: Super Root Key, an RSA key pair which forms the start of the boot-time authentication

chain. The hash of the SRK public key is embedded in the processor using OTP hardware. The

SRK private key is held by the CA. Unless explicitly noted, SRK in this document refers to the

public key only.

 UID: Unique Identifier, a unique value (such as a serial number) assigned to each processor

during fabrication.
