KEA mechanism parameters

CK_KEA_DERIVE_PARAMS; CK_KEA_DERIVE_PARAMS_PTR

CK_KEA_DERIVE_PARAMS is a structure that provides the parameters to the CKM_KEA_DERIVE mechanism. It is defined as follows: 





typedef struct CK_KEA_DERIVE_PARAMS {
CK_BBOOL isSender;
CK_ULONG ulRandomLen;
CK_BYTE_PTR pRandomA;
CK_BYTE_PTR pRandomB;
CK_ULONG ulPublicDataLen;
CK_BYTE_PTR pPublicData;
} CK_KEA_DERIVE_PARAMS;




          
isSender Option for generating the key (called a TEK). The value is TRUE if the sender (originator) generates the TEK, FALSE if the recipient is regenerating the TEK.  


ulRandomLen size of random Ra and Rb, in bytes  


pRandomA pointer to Ra data  


pRandomB pointer to Rb data  


ulPublicDataLen other party's KEA public key size  


pPublicData pointer to other party's KEA public key value  




CK_KEA_DERIVE_PARAMS_PTR is a pointer to a CK_KEA_DERIVE_PARAMS.
