Creates the shared secret value according to [IEEE1363, ANS X9.63]:
-
Checks input-parameter pointers and EC Domain in public and private keys.
-
Derives the partner public key and calls the EcWrstDhDeriveSharedSecret function, which performs EC SVDP operations.
- Note
- The term "User" refers to any party that calculates a shared secret value using this primitive. The term "Partner" refers to any other party of shared secret value calculation. Partner's public key shall be validated before using in this primitive.
- Returns
- CRYS_OK on success.
-
A non-zero value on failure as defined crys_ecpki_error.h.
- Parameters
-
[in] | PartnerPublKey_ptr | Pointer to a partner public key. |
[in] | UserPrivKey_ptr | Pointer to a user private key. |
[out] | SharedSecretValue_ptr | Pointer to an output buffer that will contain the shared secret value. |
[in,out] | SharedSecrValSize_ptr | Pointer to the size of user-passed buffer (in) and actual size of output of calculated shared secret value (out). |
[in] | TempBuff_ptr | Pointer to a temporary buffer. |
