A new secure framework in WSNs using ECC: Medical application

Wireless sensor networks can be considered as the culmination of the development of wireless technologies. It presents a new technology, which permit a communications infrastructure for monitoring and tracking. Sensor networks offer the possibility of extending the spectrum of application of wireless technologies and are used in several fields such as medical field, armed forces, agriculture and urban areas. Sensor networks are deployed in open environments that are accessible to all, creating a major challenge for administrators in providing a good quality of service or in ensuring a good level of security, especially the security of data transmitted via the network. Sensor networks are essentially composed of sensors that have very limited resources and suffer from several vulnerabilities and several potential security breaches, which mean that they are often considered as points of failure. The use of cloud computing can be considered as a good solution to resource shortfalls by providing storage resources and on-demand computing power for WSN users, and by allowing the ability to view the collected data at any time and from anywhere. In this paper we propose a framework that enables authentication, confidentiality and integrity and a quick and secure access to collected data by using the Cloud Computing. It is proposed thereafter an implementation of our framework on medical field that allows remote consultation of patients with an emergency process, and a security analysis of our system.
