Using wolfSSL to Secure Thermostats

As a lightweight, embedded SSL library, wolfSSL has been used to secure many smart home devices such as lighting, garage doors, washers and dryers, thermostats, as well as a variety of other appliances. Security may not be the first thought when developing a smart home device, but there remains the risk of an attacker gaining access to a wirelessly connected thermostat that has complete control of a home’s heating and cooling system. This could be detrimental to the utility bill, plumbing, and even pets left in the house susceptible to extreme temperatures. Imagine going on vacation during frigid weather and the home’s heating is disabled. This could cause frozen and potentially bursting pipes, which in turn could lead to flooding, costing thousands of dollars in repairs. wolfSSL is designed specifically to prevent these issues. Devices secured with wolfSSL give homeowners a necessary comfort knowing their home is resistant to wireless intruders and other security threats.
