This SKU string is required in order to retrieve the SE session that backs the SPM service. Signed-off-by: Tim Trippel <[email protected]>
This updates the PA and SPM to implement the `DeriveSymmetricKey` key RPC function. This partially addresses lowRISC#4. Signed-off-by: Tim Trippel <[email protected]>
This adds a `sival` OpenTitan Earlgrey SKU configuration for testing. Additionally this removes the execute privilege bits on the SKU YAML config files. Signed-off-by: Tim Trippel <[email protected]>
This updates the PA loadtest and integration test script to enable testing the sival SKU provisioning sequence that now includes invoking the DeriveSymmetricKey function on the PA and SPM. Part of refactoring the loadtest will enable testing additional SKUs in the future as well. Signed-off-by: Tim Trippel <[email protected]>
This enhances the `DeriveSymmetricKey` RPC function (and renames it to `DeriveSymmetricKeys`) to be able to generate multiple keys with one invocation. This will increase the performance of the provisioning system as a whole by reducing the number of round-trips between the tester and PA/SPM. Signed-off-by: Tim Trippel <[email protected]>
This updates the SPM to enable generating cSHAKE128 hashed OpenTitan lifecycle tokens using the DeriveSymmetricKeys RPC function. This partially addresses lowRISC#4. Signed-off-by: Tim Trippel <[email protected]>
