The Consolidated Protocols

WIFI TCP/IP TLS MQTT

The Consolidated Protocols WIFI WIFI

The Consolidated Protocols WIFI l By default wireless protocol at home l No need of gateway/concentrator: a commercial router present in every house. If not, easily acquirable and cheap. l High Data rate (802.11n → over 100Mbps) l Allows the use of MQTT (lightweight messaging protocol) l Implements Security → WEP, WPA, WPA2

The Consolidated Protocols model TCP/IP TCP/IP

IP addresses Not defined yet The Consolidated Protocols model TCP/IP

l Implements Error control and Flow control: reliable connexion. l Widespread protocol used in the Internet home ↔ DI Connection Manager l Allows a TCP connexion always open: Appliance ↔ DI Connection Manager The Consolidated Protocols model TCP/IP

The Consolidated Protocols TLS TLS TLS encryption/decryption

The Consolidated Protocols TLS HTTP TLS in the Internet HTTP TLS in the Internet =https

The Consolidated Protocols TLS HTTP TLS in the Internet HTTP TLS HTTP TLS in SandS MQTT TLS =https

The Consolidated Protocols TLS l Standard security protocol in the Internet l DI and all the appliances share a certificate. l Together with Wifi Security → Double Encryption

The Consolidated Protocols TLS + WIFI l Standard security protocol in the Internet l DI and all the appliances share a certificate. l Together with Wifi Security → Double Encryption Double Encryption

The Consolidated Protocols TLS + WIFI WIFI encryption WEP/WPA/WPA2 TLS encryption Double Encryption

The Consolidated Protocols MQTT MQTT MQTT encoding/decoding

The Consolidated Protocols MQTT l Extremely lightweight messaging protocol Only 2 bytes of fixed headers l Type of data does not influence the communication l Widespread Application layer protocol for: IOT Internet of things M2M Machine to machine communications

WIFI TCP/IP TLS MQTT The Consolidated Protocols in SandS
