Abstract

IoT-based healthcare is especially susceptible as many IoT devices are developed without keeping in mind the security issue. In addition, such smart devices may be connected to global networks to access anytime, anywhere. There are some security challenges like mobility, computational limitation, scalability, communication media, dynamic topology, and above all the data confidentiality in storage or in transmission. There are some security protocols and methodology which is used in IoT-based healthcare systems like steganography, AES cryptosystems, and RSA cryptographic techniques. Therefore, it is necessary to use quantum cryptography system to make sure the security, privacy, and integrity of the patient's data received and transmitted from IoT-based healthcare systems. Quantum cryptography is a very fascinating domain in cyber security that utilizes quantum mechanics to extend a cryptosystem that is supposed to be the unbreakable secure system.
