Towards an Integration of AES Cryptography into Deluge Dissemination Protocol for Securing IoTs Reconfiguration

In loT-based system, over-the-air (OTA) programming or IoTs reconfiguration plays a vital role, especially in large-scale deployments. OTA programming allows IoTs devices to be replaced and upgraded the running applications or image by the newer versions without effort on manually install one by one device. However, the development of OTA programming also meets many challenges due to the limitations of memory resources, battery energy as well as communication support of small and constraint devices. Therefore, designing OTA programming solutions supported by a strong security mechanism has been still an open issue. In this paper, an integration of AES cryptography into a well-known network programming protocol (Deluge on TinyOS 2.x) is presented. The paper not only explains Deluge protocol's operation, messages format but also provides numerical results when running this enhancement with real IoTs devices (Telosb mote on TinyOS 2.x). The developed solution can be deployed in the real IoT-based systems for securely re-configuring IoT devices and the presented empirical results can be used as a dataset for research community to compare in other environments.
