The Quantum-Mechanical Model of an Atom02:45

The Quantum-Mechanical Model of an Atom

Shortly after de Broglie published his ideas that the electron in a hydrogen atom could be better thought of as being a circular standing wave instead of a particle moving in quantized circular orbits, Erwin Schrödinger extended de Broglie’s work by deriving what is now known as the Schrödinger equation. When Schrödinger applied his equation to hydrogen-like atoms, he was able to reproduce Bohr’s expression for the energy and, thus, the Rydberg formula governing hydrogen spectra. Schrödinger...
Insensitive Nuclei Enhanced by Polarization Transfer (INEPT)01:15

Insensitive Nuclei Enhanced by Polarization Transfer (INEPT)

Insensitive Nuclei Enhanced by Polarization Transfer (INEPT) is an advanced Nuclear Magnetic Resonance (NMR) technique specifically designed to detect and enhance the signals of low-abundance nuclei, such as carbon-13 and nitrogen-15, in small molecules. The fundamental principle behind INEPT is the transfer of polarization from a more abundant and highly polarizable nucleus, typically hydrogen-1, to the low-abundance nucleus of interest. This process effectively boosts the NMR signal of the...

¹³C NMR: Distortionless Enhancement by Polarization Transfer (DEPT)

When proton-coupled carbon-13 spectra are simplified by a broadband proton decoupling technique, structural information about the coupled protons is lost. Distortionless enhancement by polarization transfer (DEPT) is a technique that provides information on the number of hydrogens attached to each carbon in a molecule. While the DEPT experiment utilizes complex pulse sequences, the pulse delay and flip angle are specifically manipulated. The resulting signals have different phases depending on...
Information Processing Approach01:30

Information Processing Approach

The information-processing theory of cognitive development centers on fundamental mental processes, including attention, memory, and problem-solving skills. Researchers in this field examine how cognitive abilities, such as working memory, evolve and influence children's overall development. Studies indicate that children with stronger working memory tend to excel in reading comprehension, math, and problem-solving compared to peers with less efficient memory skills. Low working memory is also...

Area of Science:

  • Cybersecurity
  • Cryptography
  • Healthcare Technology

Background:

  • The Internet of Medical Things (IoMT) offers transformative healthcare delivery but faces significant security vulnerabilities, particularly from quantum computing.
  • Existing security measures are insufficient against advanced threats, necessitating novel cryptographic approaches.

Purpose of the Study:

  • To propose a lightweight, privacy-preserving authentication scheme for edge-based IoMT environments.
  • To enhance security resilience against quantum attacks using NIST-standardized post-quantum primitives.
  • To ensure secure session key establishment, message integrity, authentication, and non-repudiation.

Main Methods:

  • Integration of CRYSTALS-Kyber Key Encapsulation Mechanism (KEM) for secure key establishment.
  • Utilization of CRYSTALS-Dilithium for digital signatures to ensure message integrity and authentication.
  • Formal security verification using the AVISPA tool under the Dolev-Yao model and BAN logic.
  • Implementation of a two-phase process: Registration and Authentication involving patients, devices with PUFs, specialists, edge nodes, and cloud servers.

Main Results:

  • The proposed scheme provides mutual authentication among all participating entities, ensuring secure access to sensitive health information.
  • Formal verification confirmed that all security goals (authenticity, secrecy) are achieved, with no attacks detected.
  • Performance evaluations demonstrated computational efficiency, making the scheme suitable for resource-constrained IoMT devices.

Conclusions:

  • The developed authentication framework effectively addresses the security challenges posed by quantum computing in IoMT environments.
  • The integration of post-quantum cryptography enhances the cryptographic robustness of edge-based IoMT systems.
  • The scheme aligns with the goal of securing Internet of Things (IoT) ecosystems with advanced cryptosystems.
