We've long heard about the wide functionality that home automation technologies offer for improving our lives and securing our houses. However, price and an unstable domotics market have restricted such systems' deployment. Nowadays, companies offer too technology-dependent solutions that don't cover user demands completely. Meanwhile, research works focus on small innovations on specific parts of home automation systems, which don't consider integration and deployment issues to present practical designs. The system presented in this article considers user requirements, including novel advances, all in an integral home automation solution suitable for many services. The architecture's modular nature allows direct adaptation to specific cases using standard domotic technologies, for managing in-house devices, and a proposal of an IP-based network for connecting the main home automation module with other platform elements. A remote security system has been developed, and managing tasks are enabled via in-home control panels and an advanced 3D application for local and remote homeowner access. The system has been deployed on a prototype house, testing a wide set of domotic services. Moreover, the range of indoor pervasive applications has also been extended to e-health, elderly adaptation, greenhouse automation, and energy efficiency.

Luckily, new communication technologies and protocols are nowadays designed considering security issues. A clear example of this can be found in the Internet of Things (IoT) field, a quite recent area where communication technologies such as ZigBee or IPv6 over Low power Wireless Personal Area Networks (6LoWPAN) already include security features to guarantee authentication, confidentiality and integrity. More recent technologies are Low-Power Wide-Area Networks (LP-WAN), which also consider security, but present initial approaches that can be further improved. An example of this can be found in Long Range (LoRa) and its layer-two supporter LoRa Wide Area Network (LoRaWAN), which include a security scheme based on pre-shared cryptographic material lacking flexibility when a key update is necessary. Because of this, in this work, we evaluate the security vulnerabilities of LoRaWAN in the area of key management and propose different alternative schemes. Concretely, the application of an approach based on the recently specified Ephemeral Diffie–Hellman Over COSE (EDHOC) is found as a convenient solution, given its flexibility in the update of session keys, its low computational cost and the limited message exchanges needed. A comparative conceptual analysis considering the overhead of different security schemes for LoRaWAN is carried out in order to evaluate their benefits in the challenging area of LP-WAN.
