KEYS: trusted: caam based protected key

2025-10-20T04:10:28Z

- CAAM supports two types of protected keys: -- Plain key encrypted with ECB -- Plain key encrypted with CCM Due to robustness, default encryption used for protected key is CCM. - Generate protected key blob and add it to trusted key payload. This is done as part of sealing operation, which is triggered when below two operations are requested: -- new key generation -- load key, Signed-off-by: Pankaj Gupta Signed-off-by: Meenakshi Aggarwal Signed-off-by: Herbert Xu

crypto: caam - enable prediction resistance in HRWNG

2020-03-30T00:50:50Z

Instantiate CAAM RNG with prediction resistance enabled to improve its quality (with PR on DRNG is forced to reseed from TRNG every time random data is generated). Management Complex firmware with version lower than 10.20.0 doesn't provide prediction resistance support. Consider this and only instantiate rng when mc f/w version is lower.

crypto: caam - add Derived Key Protocol (DKP) support

2017-12-28T06:56:48Z

Offload split key generation in CAAM engine, using DKP. DKP is supported starting with Era 6. Note that the way assoclen is transmitted from the job descriptor to the shared descriptor changes - DPOVRD register is used instead of MATH3 (where available), since DKP protocol thrashes the MATH registers. The replacement of MDHA split key generation with DKP has the side effect of the crypto engine writing the authentication key, and thus the DMA mapping direction for the buffer holding the key has to change from DMA_TO_DEVICE to DMA_BIDIRECTIONAL. There are two cases: -key is inlined in descriptor - descriptor buffer mapping changes -key is referenced - key buffer mapping changes Signed-off-by: Horia Geantă Signed-off-by: Herbert Xu
