Security Architecture for Vehicle to Emergency Services (V2S) Communicating Over MQTT-SN

Ensuring rapid and secure communication between cars and emergency services is of utmost importance in contemporary transportation networks to enable prompt reaction to urgent circumstances. The reliability and trustworthiness of vehicle-to-emergency services (V2S) communication, ensuring the safety and well-being of vehicle occupants and facilitating rapid emergency assistance when needed. We have proposed a security architecture for V2S communication that employs MQTT-SN protocol, RSA encryption, and SHA-256 hashing algorithm to ensure efficient message exchange, secure data transmission, and message payload integrity verification.
