Abstract
One of the major applications of the Heterogeneous Network (HetNet) is in the healthcare system. Deploying HetNet in healthcare systems enables patients, physicians, and other stakeholders to communicate easily with each other. Due to the large growth in the network’s subscribers, the security of the stored health data became one of the major concerns because unauthorized access to this data may lead to very serious complications, and unreliable transmission of data may lead to fatal risks to the patient’s life. Therefore, taking data integrity into consideration, user authentication has become one of the main factors. However, significant research work has been performed at HetNet’s physical layer to secure communication, but the result of this leads to an increase in hardware components. The increasing hardware components not only costs money but also power consumption. Therefore, this paper presents an alternate way of securing communication in HetNet at the network layer. However, resolving security problems at the network layer increases computational complexity. Nevertheless, earlier, some encryption techniques like identity-based encryption (IBE), symmetric key encryption (SKE), and public-key encryption (PKE) have been utilized for securing data. Due to their own disadvantages, this paper utilizes an attribute-based encryption (ABE) authentication scheme for securing health data in medical applications. With the help of this method, access to the intruders is denied which results in reduced communication overhead. This authentication scheme helps protect the essential information against attacks by the intruders. It includes a third party server that helps to authenticate and store patient’s information. The whole security technique has been written in the form of HLPSL (high-level protocol specification language) codes, and the results are then validated with the help of AVISPA (automated validation of Internet security protocols and applications) tool.
Highlights
Nowadays, wireless communication has developed its essence in wide solicitations of current advanced domain like safety, medical, rescue, and security purposes [1]
This data is at the highest risk of being attacked by an intruder as the message is sent in plain-text
When this malicious data is received by Alice, it assumes that it is being sent by Bob, which is not true, and in a crucial application like healthcare, it can prove hazardous
Summary
Wireless communication has developed its essence in wide solicitations of current advanced domain like safety, medical, rescue, and security purposes [1]. 2.1 Security-related work at physical layer on HetNet Several accomplishments have been dedicated to security problems in HetNets for the past few years, such as Hu et al [2] recently examined the PLS in HetNets backed by SWIPT to boost the safety issue They inserted artificial sound in the communicated beam together with the macrocell and femtocell base stations. This research article proposes an ABE authentication scheme to secure data in medical-dedicated HetNet. 2.2 Security-related work for medical application Issues regarding protecting the privacy of patients and the security of medical details are two basic problems with the proper use of electronic medical services [33]. SKE is faster as it utilizes only one key for encryption and decryption, but exchanging this key secretly between the users is a big problem [20] All these techniques are used for securing the essential health data of users at the network layer.
