TLS and DTLS are widely deployed security protocols. Because of the increasing number of security vulnerabilities found in Internet of Things (IoT) devices, the TLS and DTLS protocols are now frequently incorporated into those devices. But when used incorrectly, TLS/DTLS can be inefficient. One common problem with IoT devices, which sleep for extended periods to lower their power consumption, is breaking an ongoing DTLS communication.
In this hackathon we will work on making Datagram Transport Layer Security (DTLS) more efficient by using the Connection ID extension. This new extension is currently being developed in the IETF TLS working group.
Your code will run on an Arm-based microcontroller and should switch IP addresses and ports through a Network Address Translator (NAT) without impacting the DTLS communication. We will use an open source, embedded DTLS/TLS library called Mbed TLS.
The relevant resources can be found at:
- Mbed TLS library: https://github.com/ARMmbed/mbedtls
- IETF Connection ID draft https://tools.ietf.org/html/draft-ietf-tls-dtls-connection-id
- Mbed TLS webinar: http://www2.keil.com/mbed/mbedtls
We will use the Arm-enabled developer board FRDM-K64F.
We will also use the professional development environment, Arm Keil uVision 5.
For those who prefer different development environments, we also offer Mbed CLI, the Mbed Online Compiler, and Mbed Studio.
