Security is a major issue for the internet of things, and a prerequisite for wide consumer adoption. The Chrysler hack (2015) is an illustration of this trend.
Regarding the IoT security the two major aspects are security for the things and security for the devices (typically a smartphone) that collect data from the things and forwards them to the cloud. EtherTrust designs IoT security module for both aspects.
More precisely EtherTrust develops TLS/DTLS stack secure element (see https://tools.ietf.org/html/draft-urien-uta-tls-dtls-security-module-00) compatible with COAP environments such as:
- Smartphone acting as IoT aggregators
- Device for IoT frameworks (wireless sensors, wearable, health devices, connected cars…)
