Caliptra DICE Certificates do not include required extensions to indicate the key usage (see TCG DICE Certificate Profile Spec).

  • LDEVID shall contain:
    - tcg-dice-kp-identityLoc (because it is a Local Identity)
    - tcg-dice-kp-eca (because it is an embedded CA)
  • FMC_Alias shall contain:
    - tcg-dice-kp-eca (because it is an embedded CA)
    - tcg-dice-kp-attestLoc (because we use it to sign PCRs)
    - RT_Alias shall contain:
    - tcg-dice-kp-eca (because it is an embedded CA)
  • DPE LEAF shall contain:
    - tcg-dice-kp-attestLoc (because it is used to sign DPESign requests)
  • DPE CA (in case of cdi-export) shall contain
    - tcg-dice-kp-eca (because it is an embedded CA)
