Security Issues of Internet of Things in Health-Care Sector: An Analytical Approach

Abstract

Internet of Things (IoT) has created an impetus to digitalizing numerous processes in day to day life. It soberly refers to interconnection of computing devices via the Internet using radio frequency identification system (RFID) and allows the objects, sensors, and everyday items to make use of computing capabilities together with the network connectivity to exchange the data with minimum human intervention. Due to openness, IoT systems are susceptible to many attacks. These attacks can damage devices physically besides network connections. A layered architecture has inbuilt primitive security solution even if it is still vulnerable to attacks. Therefore, many cryptographic solutions or algorithms for IoT have been proposed in which the most popular algorithms are symmetric algorithm and asymmetric lightweight algorithm. The symmetric algorithm provides integrity, confidentiality, and small key size with less complexity but less capacity to offer authenticity and key distribution. Asymmetric lightweight algorithms are more complex but pros are that they provide confidentiality, integrity, authenticity, and diminutive key size. RSA (Rivest-Shamir-Adleman) and elliptic curve cryptography (ECC) are popular asymmetric lightweight algorithms. IoT faces many other challenges like scalability, clout, bandwidth, security, and privacy. This chapter discusses various IoT security concerns and key security issues. Security architecture has also been discussed in this pursuit. Further, layered classification of radio frequency identification and (RFID), and wireless sensor network (WSN) is also incorporated. Moreover, this chapter entails cryptographic solutions for IoT. Over and above, security issues in medical and business sectors have been discussed with case study. This chapter also renders architecture for security in the medical sector.
