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.

curveID

public TPM_ECC_CURVE curveID

ECC curve ID

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.

Constructor Detail

TPMS_ECC_PARMS

public TPMS_ECC_PARMS(TPMT_SYM_DEF_OBJECT _symmetric,
                      TPMU_ASYM_SCHEME _scheme,
                      TPM_ECC_CURVE _curveID,
                      TPMU_KDF_SCHEME _kdf)

This structure contains the parameters for prime modulus ECC.

Parameters:

_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 - 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)

_curveID - ECC curve ID

_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_SCHEME_MGF1, TPMS_SCHEME_KDF1_SP800_56A, TPMS_SCHEME_KDF2, TPMS_SCHEME_KDF1_SP800_108, TPMS_NULL_KDF_SCHEME)
