Secure communication protocols for IoT
Secure communication protocols for IoT IoT devices often operate at the edge with limited power and memory. Protecting data in transit is essential to stop eavesdropping, tampering, and impersonation. The right protocol mix depends on the network and the device, and it should also support simple management over time. TLS for TCP-based links: Use TLS 1.3 whenever possible. It delivers strong encryption, forward secrecy, and a cleaner cipher negotiation. For devices with tight power budgets, enable session resumption and keep handshakes short to save energy. ...
