A Secure Framework for Internet of Medical Things Security Based System Using Lightweight Cryptography Enabled Blockchain

The Internet of Medical Things (IoMT) is a growing paradigm that offers several efficient and productive solutions for the treatment of various ailments for both patients and medical professionals. The IoMT has many advantages, but security remains a problem that must be overcome. The inexperienced IoMT users' lack of security and privacy consciousness and the possibility of multiple middleman attacks for getting the healthcare information, seriously puts the use of IoMT in jeopardy. Therefore, this paper proposes a lightweight cryptography enabled with blockchain for enhancing IoMT-based security and privacy. The study utilizes lightweight cryptography to securely uploading the data to the cloud database for privacy preservation, and the Blockchain technology is use to securely store the data in the cloud server. The experimental results of the proposed model revealed a better result with compare with prevailing methods. The proposed system achieves an accuracy of 98% of security level.
