STCP Protocol
STCP (Secure TCP Protocol) is a high-performance secure communication protocol designed for modern networking environments.
It combines strong encryption, low-latency communication, and scalable architecture to provide fast and secure data transmission between systems.
STCP is designed for embedded devices, infrastructure platforms, IoT environments, and advanced client-server applications where performance, security, and reliability are critical.
Session keys are generated dynamically using ECDH without pre-shared secrets, certificates, or static encryption keys.
"STCP MQTT for nRF9151 was developed from an initial commit on February 27, 2026, to a fully working demonstration in approximately three months. The implementation consists of roughly 15,000 lines of C and Rust code and provides end-to-end encrypted MQTT communication over LTE-M using STCP as the transport layer." --Lauri
