Why Is Public Key Authentication Essential for Secure Connections?

Public key authentication plays a pivotal role in securing SSH connections for IoT devices. Unlike traditional password-based authentication, public key authentication relies on cryptographic keys to verify user identity. This method significantly reduces the risk of unauthorized access, as attackers cannot easily guess or crack cryptographic keys.

Generate a pair of keys: public and private.
Install the public key on the server.
Store the private key securely on your local machine.

When connecting to the server, the client uses the private key to prove its identity, eliminating the need for passwords. This approach enhances security by reducing the attack surface and minimizing the likelihood of successful brute-force attacks. By implementing public key authentication, you add an additional layer of protection to your IoT network, ensuring only authorized devices can establish connections.
