Proposing secure and lightweight authentication scheme for IoT based E-health applications

The Internet of Things (IoT) is the collection of connected smart devices\objects through internet network. The rapid development of IoT and vast expansion of wireless technologies unfold the new chances of growth in several domains such as, Education, Transportation, Agriculture, and especially in the Healthcare sector. Introducing the IoT through healthcare applications fetch several benefits, including cost savings through lowered hospital visiting costs, health care provider costs, transportation costs, human resource costs and the insurance costs. It leads to an added advantage of improved quality care in health care. However, increasing use of the IoT services in E-health applications has led to increase the concerns of security and privacy, especially in healthcare domain. In fact, healthcare applications are prone to data breaches and widening issues in security aspects owing to increasing number of access points to sensitive data through electronic medical records, as well as the rising popularity of wearable technology. For example, of these issues, authentication of the different connected entities, energy efficiency and exchanged data confidentiality form the major concerns for users. Therefore, the successful deployment of IoT-based E-health application rely on overcome the major security concerns for the users which needs to be addressed in energy efficient way. Though a number of researches have conducted for lightweight secure authentication, there is still a great room for further research to address security challenges as well as its energy efficiency for those security authentication schemes in IoT. There is a great need to design and develop a lightweight secure authentication model, which offers significant security level against multiple attacks such as mainly: Impersonation attacks, man in the middle attack and unknown key sharing attacks for IoT base E-health domain. This research proposed a secure group-based lightweight authentication scheme for IoT based E-health applications, the proposed model will provide mutual authentication and energy efficient, and computation for healthcare IoT based applications. Which will use elliptic curve cryptography (ECC) principles that provide mentioned featured of suggested model.
