Security of 6LoWPAN IoT Networks in Hospitals for Medical Data Exchange

Abstract

It is well known that available approaches to IoT networks eschew certain security issues that may expose sensitive data to unauthorized entities. This paper proposes a security protocol for the IoT based communication. This protocol comprises of three levels of security checks namely authentication, confidentiality and integrity. Such algorithms do require large storage capacity and processing powers. However, nodes in IoT network have limited storage capacity and processing power. Proposed algorithm overcome this problem by reducing the number computations performed without losing the accuracy of data. Trust, Security and Privacy is established over a 6LoWPAN network running on RPL by keeping the CPU power consumption and storage requirements under check. The implementation of the proposed security scheme has been demonstrated for IoT based hospital networks in simulation with Cooja Network Simulator on Contiki OS
