The Consumer-Centric Internet of Medical Things (CCIoMT) is an assortment of clinical hardware and Internet of Things (IoT) that garners real-time data through remote monitoring and reduces doctor-consumer or patient interaction, enhancing the quality of remedies for the healthcare system. However, the facile availability and accessibility of medical data on the web have become a significant cause for information security and trustworthiness disputes in CCIoMT. The computerized algorithm employs a cryptography strategy to accomplish security services like protection, trustworthiness, and non-repudiation. Recently, researchers have developed a variety of advanced signature algorithms for CCIoMT. However, the existing advanced schemes depend on traditional difficult numerical problems like discrete logarithm problems and computational Diffie-Hallman problems, which are unable to safeguard them from rising quantum assaults and some have high computational expanse issues. Lattice-based cryptographic algorithms are one of the solutions to quantum assaults. Therefore, this article portrays a certificateless sequential aggregate signature scheme with the assistance of the smallest integer solution (SIS) and shortest vector problem (SVP) of the NTRU lattices for the CCIoMT network. The proposed scheme aims to provide efficient security solutions for resource-constrained consumer electronics within CCIoMT environments. The portrayed signature scheme’s security and operability are shown through security analysis and the performance assessment with some pre-existing mechanisms. The results indicate that the proposed algorithm is suitable for CCIoMT.
