Elliptic Curve Integrated Encryption Scheme (ECIES) is a type of Integrated Encryption Scheme (IES) that uses Elliptic-Curve Diffie-Hellman (ECDH) key agreement to establish an ephemeral data key (rather than a session key) which is then used to encrypt data using a symmetric scheme. It uses an ephemeral key during the creation … inateck microsoft surface dockingstation
