Things that connect to other devices & systems via Internet or communication networks are called IoT. It can also be said as a network of wireless sensors connected to a cloud and controlled by embedded devices. Considering the large framework of IoT, it becomes a little difficult to maintain security at each sensor node especially with limited information regarding hardware and deployment capabilities. Therefore, management of keys has become a point of concern peculiarly taking account of node capturing attack. This paper proposes an advanced cluster key management scheme for agriculture precision which involves EBS constructor and Chinese remainder theorem together. Once the data is collected from the nodes and a list is created, it is sent from the Cluster Head to the Backend Server, which filters it for hostile IDs and ignore the unauthentic sensor, returning filtered list with preloaded keys, & an authentication code to Cluster Head for use. To ensure added security, in this scheme encryption of data is done twice. Upon comparing the proposed scheme with others, it has been observed that we have achieved higher delivery ratio and reduced the energy consumption and packet drop rate to a great extent.

With constant evolution of technology, Internet of Things (IoT) is drawing much attention in recent years in various application domains from Wearables and Agriculture to Smart Cities, with Healthcare being one of the arenas. With Internet of Things in action, a new generation of healthcare is being introduced with assuring outlooks. This paper reviews the progress that has been made with the successful amalgamation of internet and healthcare department. Further this paper discusses various types of IoT based healthcare services and applications that have been introduced so far along with different prospects and scope of future research.
