Secure Healthcare Information Communication over Internet under patient-cloud communication model

The healthcare networks consist of the wireless sensors to monitor the patient’s health, hence called wireless body area networks (WBANs). The healthcare networks carry the information of many patients. The information privacy becomes the primary concern for the healthcare networks. The privacy concerns raise various issues which includes the information altercation attacks leading to threat. The information altercation (like replay attack) attacks can change the healthcare emergency decisions by changing the patient information on the cloud based healthcare information model. In this paper, we have proposed a novel key exchange algorithm to enhance the level of privacy in the cloud based healthcare model. The proposed key management model is a lightweight crypto key exchange with quick response key model. The key model has been proposed to be used between the patient-cloud communications. The data privacy and confidentiality is protected by exchanging the key in the periodic fashion. The proposed model has been evaluated on the basis of various performance parameters of probability of key exposure and probability of key connectivity. The experimental results have shown the effectiveness of the proposed model.
