APPLICABLE LIGHT-WEIGHT CRYPTOGRAPHYTOSECURE MEDICAL DATA IN IOT SYSTEMS

Abstract

Different applications require different level of security where the scarce of resource plays effective role. In order to protect the private medical data in the internet of things (IoT) field, the search for the optimal encryption algorithm is a must. Electronic sensors are used to collect medical data from the patient's body acquiring its transmission to the healthcare system securely. It is essential to ensure trust and data secrecy from the starting point-sensors throughout the medical treatment to prevent any unauthorized access or unneeded interruption. Thus, data encryption from the beginning sensors is necessary but facing all limitations in computing complexity, power consumption and communication bandwidth, where the normal available crypto-algorithms are considered heavyweight is completely unpractical. This work study several realistic lightweight encryption algorithms suitable for IoT medical systems. The paper outlines a comparison between ten applicable cryptographic algorithms resulting fair analysis in terms of memory utilization and speed. The investigation deduces the optimal candidate algorithm for the proposed health care system considering the balance between the optimal requirement and the future threats.
