SSH keys provide a more secure alternative to passwords. They consist of a pair of cryptographic keys: a public key and a private key. The public key is stored on the server, while the private key is kept securely on the client device. When the client attempts to authenticate, it uses its private key to digitally sign a challenge from the server. The server then verifies the signature using the client's public key. If the signature is valid, the client is authenticated without ever having to transmit a password over the network. This eliminates the risk of password interception and replay attacks.
When setting up remote SSH access for IoT devices, security should always be your top priority. Use strong passwords or, preferably, SSH keys for authentication. Keep your SSH software up to date to patch any security vulnerabilities. Consider implementing two-factor authentication for an extra layer of security. Restrict access to the IoT device to only those users who absolutely need it. Monitor your SSH logs for any suspicious activity.
