Introduction to SSH Key Management
SSH (Secure Shell) is a cryptographic network protocol used for secure communication between devices over an unsecured network. It is widely used for remote access to servers, IoT devices, and other systems. SSH keys provide a secure method of authentication, replacing traditional password-based systems that are vulnerable to brute-force attacks.
When managing multiple Raspberry Pi devices in an IoT network, SSH key management becomes critical. SSH keys consist of a public key and a private key. The public key is stored on the server (Raspberry Pi), while the private key remains with the user. This ensures that only authorized users with the private key can access the device. Proper SSH key management involves generating, storing, and rotating keys securely.
Why Choose RemoteIoT Platforms?
RemoteIoT platforms are designed to simplify the management of IoT devices, including Raspberry Pi. These platforms offer several advantages:
