Diffie-hellman key modulation
WebElliptic Curve Diffie Hellman (ECDH) is an Elliptic Curve variant of the standard Diffie Hellman algorithm. See Elliptic Curve Cryptography for an overview of the basic concepts behind Elliptic Curve algorithms.. ECDH is used for the purposes of key agreement. Suppose two people, Alice and Bob, wish to exchange a secret key with each other. WebThe Diffie-Hellman key-exchange algorithm is a secure algorithm that offers high performance, allowing two computers to publicly exchange a shared value without using …
