EDHOC specification: EDHOC. EDHOC is a key exchange protocol designed to run over CoAP or OSCOAP. The communicating parties run an Elliptic Curve Diffie-Hellman (ECDH) key exchange protocol with ephemeral keys, from which a shared secret is derived.

Mar 15, 2019 · Elliptic-curve Diffie-Hellman. Elliptic-curve Diffie-Hellman takes advantage of the algebraic structure of elliptic curves to allow its implementations to achieve a similar level of security with a smaller key size. A 224-bit elliptic-curve key provides the same level of security as a 2048-bit RSA key. This can make exchanges more efficient and ECDH-Curve25519-Mobile implements Diffie-Hellman key exchange based on the Elliptic Curve 25519 for Android devices. ECDH-Curve25519-Mobile is based on the NaCl crypto implementation, more specifically AVRNaCl, written by Michael Hutter and Peter Schwabe, who dedicated their implementation to the public domain. Oct 24, 2013 · CloudFlare uses elliptic curve cryptography to provide perfect forward secrecy which is essential for online privacy. First generation cryptographic algorithms like RSA and Diffie-Hellman are still the norm in most arenas, but elliptic curve cryptography is quickly becoming the go-to solution for privacy and security online.
