ECDHE (Elliptic Curve Diffie-Hellman Ephemeral) Explained 🔐 | Security+

Elliptic Curve Diffie-Hellman Ephemeral (ECDHE) is a key exchange algorithm based on Elliptic Curve Cryptography (ECC). It is a variant of the Diffie-Hellman key exchange protocol that uses elliptic curves to enable two parties to securely generate a shared secret over an insecure communication channel. The "ephemeral" aspect means that a new key is generated for each session, providing Perfect Forward Secrecy (PFS).

The Security+ exam may include questions on cryptographic protocols and key exchange mechanisms. Understanding the principles of ECDHE, its role in establishing secure communication channels, and its contribution to Perfect Forward Secrecy can be relevant for exam preparation.
