ECDHBasicAgreement class
P1363 7.2.1 ECSVDP-DH
ECSVDP-DH is Elliptic Curve Secret Value Derivation Primitive,
Diffie-Hellman version. It is based on the work of DH76, Mil86,
and Kob87. This primitive derives a shared secret value from one
party's private key and another party's public key, where both have
the same set of EC domain parameters. If two parties correctly
execute this primitive, they will produce the same output. This
primitive can be invoked by a scheme to derive a shared secret key;
specifically, it may be used with the schemes ECKAS-DH1 and
DL/ECKAS-DH2. It assumes that the input keys are valid (see also
Section 7.2.2).
