DTLS for Lightweight Secure Data Streaming in the Internet of Things

The huge number of sensors envisioned to be deployed within Internet of Things applications will result in large amounts of likely confidential data that will be required to traverse the open Internet. This confidential data could range from the current security status of a smart house to the current health status of an elderly person connected to smart monitors. A secure and able connection will be required to connect either a cloud based or an in-house server to the embedded sensors. The ability to ensure that the data generated by the sensor networks is securely streamed to the central server will allow for real time access to the data. The use of the less favoured Datagram Transport Layer Security protocol is compared with the widely used Transport Layer Security protocol. The research shows that Datagram Transport Layer Security is a capable alternative to Transport Layer Security when it comes to streaming data across the Internet from connected Wireless Sensor Networks.
