WebMar 14, 2024 · ECDH is known as a Key Encapsulation Mechanism, which as you mention is similar to public key encryption, but not the same. There are many reasons to prefer KEMs, I will quickly mention one. First, note that a KEM is (formally) a tuple of three algorithms ( K G e n, E n c a p s, D C a p s), where

ECDH is a protocol that allows two parties to establish a shared secret over an insecure channel. Each party has a public-private key pair. The public key is sent from each party to the other one. The private key must be kept secret. A shared secret is data that is known only to the involved parties. pho asheboro ncWebECDH is a method for key exchange and ECDSA is used for digital signatures. ECDH and ECDSA using 256-bit prime modulus secure elliptic curves provide adequate protection for sensitive information.
