Elliptic Curve Cryptography - OpenSSLWiki

WebElliptic-curve Diffie–Hellman (ECDH) is a key agreement protocol that allows two parties, each having an elliptic-curve public–private key pair, to establish a shared secret over an insecure channel. This shared secret may be directly used as a key, or to derive another key.The key, or the derived key, can then be used to encrypt subsequent communications … WebTeX-Cryptography uses different ways and technics to provide – • Meta and data channel: this layer is between the sender and the recipient. The SDN sends openflow Information through the meta channel and separates the actual data channel. • Virtual Cable: each end-to-end encrypted channel is a secure channel.
