Advancement in the area of wireless communication has increased the demands for lightweight security schemes as the sensor nodes and the devices used in these networks are resource constrained devices.One such area where the lightweight cryptographic system can be applied is the medical Internet of things.Since most of the devices in medical IOT is resource constrained it poses a challenge to traditional cryptographic algorithms which tend to lower the network performance as it requires high computational complexities, power consumption, and delays and hence the need for lightweight security in these devices.To prevent any unauthorized access or interruption it is crucial to ensure that data secrecy is maintained throughout the medical treatment.The most crucial thing in securing these resource constrained devices is the key used in encryption process since the entire security of the data is dependent on the key used.Even if the attacker has little knowledge of the key used in the encryption process, the entire security of the system can be lost.In this paper a lightweight key scheduling algorithm is proposed which can be used to generate the keys to be applied for encryption process in IOT devices used in medical care to improve the security of data transmitted in the healthcare environment.
