Firefly (key exchange protocol)

Firefly is a key exchange protocol designed to securely establish shared keys between parties over a potentially insecure communication channel. It's part of a broader category of cryptographic protocols known as key exchange protocols, which allow two or more parties to generate a shared secret that can be used for encryption or authentication, without the need to exchange the secret itself directly. One of the notable features of Firefly is its emphasis on efficiency and computational security, especially in environments with limited resources or specific requirements for speed and bandwidth.
