Summary
This document is a technical report detailing the integration of the CyaSSL embedded SSL library into the INSTEON Hub, a central device for managing smart home automation. The report outlines the requirements for a compact and efficient SSL library that could operate within the constraints of embedded systems, specifically on Microchip PIC32 boards. It explains the challenges faced with previous options like OpenSSL, which did not meet the necessary criteria for certificate revocation. The development team at INSTEON selected CyaSSL due to its lightweight design and compatibility with their existing infrastructure. The report further describes how CyaSSL enhances the security of communications between the Hub and cloud services, ensuring reliable operation even during network outages. Additionally, it highlights the support provided by wolfSSL, which facilitated the integration process. Overall, the implementation of CyaSSL has allowed INSTEON to maintain secure communications within their connected home ecosystem.
