Secret Key Agreement Schemes in IOT Based Wireless Body Area Network

Internet of Things (IOT) is one of the most emerging technologies that have engrossed a lot of opportunities these days. It offers a huge business scope for organizations and open new ventures for many existing sectors. Wireless Body Area Networks (WBAN) is one such emerging field that provides a remote mechanism to monitor and collect patient's health related data using IOT based wearable bio-sensors. It has a huge potential to enhance health care delivery significantly by using remote monitoring, disease or performance tracking, and related medical procedures. The collected data is highly private in nature and must therefore be protected while being used by the healthcare professionals and during remote storage in Electronic Healthcare Repository (EHR). Traditional cryptographic techniques are highly greedy in terms of computation, storage, and energy consumption. Their implementations are found to be unsuitable in IOT devices which are highly resource constraints. This work is an effort to analyze security architecture of IOT based WBAN on the basis of security key agreement schemes.
