Class TPMS_ECC_PARMS

    • Field Detail

      • symmetric

        public TPMT_SYM_DEF_OBJECT symmetric
        For a restricted decryption key, shall be set to a supported symmetric algorithm, key size. and mode. if the key is not a restricted decryption key, this field shall be set to TPM_ALG_NULL.

      • scheme

        public TPMU_ASYM_SCHEME scheme
        If the sign attribute of the key is SET, then this shall be a valid signing scheme. NOTE If the sign parameter in curveID indicates a mandatory scheme, then this field shall have the same value. If the decrypt attribute of the key is SET, then this shall be a valid key exchange scheme or TPM_ALG_NULL. If the key is a Storage Key, then this field shall be TPM_ALG_NULL. One of: TPMS_KEY_SCHEME_ECDH, TPMS_KEY_SCHEME_ECMQV, TPMS_SIG_SCHEME_RSASSA, TPMS_SIG_SCHEME_RSAPSS, TPMS_SIG_SCHEME_ECDSA, TPMS_SIG_SCHEME_ECDAA, TPMS_SIG_SCHEME_SM2, TPMS_SIG_SCHEME_ECSCHNORR, TPMS_ENC_SCHEME_RSAES, TPMS_ENC_SCHEME_OAEP, TPMS_SCHEME_HASH, TPMS_NULL_ASYM_SCHEME.

      • kdf

        public TPMU_KDF_SCHEME kdf
        An optional key derivation scheme for generating a symmetric key from a Z value If the kdf parameter associated with curveID is not TPM_ALG_NULL then this is required to be NULL. NOTE There are currently no commands where this parameter has effect and, in the reference code, this field needs to be set to TPM_ALG_NULL. One of: TPMS_KDF_SCHEME_MGF1, TPMS_KDF_SCHEME_KDF1_SP800_56A, TPMS_KDF_SCHEME_KDF2, TPMS_KDF_SCHEME_KDF1_SP800_108, TPMS_SCHEME_HASH, TPMS_NULL_KDF_SCHEME.
