ECDHBasicAgreement

Class Overview

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).
