The Z-Scheme of Electron Transport in Photosynthesis01:34

The Z-Scheme of Electron Transport in Photosynthesis

13.9K
The light reactions of photosynthesis assume a linear flow of electrons from water to NADP+. During this process, light energy drives the splitting of water molecules to produce oxygen. However, oxidation of water molecules is a thermodynamically unfavorable reaction and requires a strong oxidizing agent. This is accomplished by the first product of light reactions: oxidized P680 (or P680+), the most powerful oxidizing agent known in biology. The oxidized P680 that acquires an electron from the...

Drug Control Governance: Regulatory Bodies and Their Impact

570
Drug control governance involves the oversight and regulation of pharmaceuticals to ensure their safety and efficacy while preventing illegal drug use and trafficking. Regulatory bodies, including the US Food and Drug Administration (FDA) and the European Union's European Medicines Agency (EMA), play a central role in this process. These agencies evaluate the safety and efficacy of drugs before they can be marketed. They fund clinical trials and assess the benefits and risks associated with...

Protein Networks02:26

Protein Networks

4.6K
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Network Covalent Solids02:18

Network Covalent Solids

16.2K
Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...

Body Temperature01:25

Body Temperature

4.9K
The body's temperature, measured in degrees, is determined by the balance between heat production and dissipation to the surrounding environment. For instance, if exercising vigorously, the body will produce more heat, causing sweat and dissipating that heat. Despite extreme environmental conditions and physical exertion, the human temperature-control system maintains a constant core body temperature (the temperature of deep tissues, which are the tissues located beneath the skin and other...

Area of Science:

  • Computer Science
  • Cybersecurity
  • Healthcare Technology

Background:

  • Wireless Body Area Networks (WBANs) enable real-time physiological data transmission for remote patient monitoring.
  • Integrating WBANs into the Internet of Things (IoT) ecosystem presents significant security and privacy challenges for sensitive medical data.
  • Existing access control protocols often struggle with the heterogeneity of devices in IoT healthcare environments.

Purpose of the Study:

  • To propose a novel heterogeneous signcryption scheme for secure data exchange between different cryptographic environments (Certificateless Cryptography and Identity-Based Cryptography).
  • To design a robust heterogeneous access control protocol for WBANs within the IoT ecosystem, addressing security and privacy concerns.
  • To provide formal security proofs and evaluate the efficiency of the proposed protocol.

Main Methods:

  • Development of a heterogeneous signcryption scheme combining Certificateless Cryptography (CLC) and Identity-Based Cryptography (IBC).
  • Design of a heterogeneous access control protocol utilizing the proposed signcryption scheme for WBANs in IoT.
  • Formal security analysis including indistinguishability against adaptive chosen ciphertext attack and unforgeability against adaptive chosen message attack in the random oracle model.

Main Results:

  • The proposed heterogeneous signcryption scheme and access control protocol effectively secure physiological data streams in a mixed cryptographic environment.
  • Formal security proofs confirm the scheme's resilience against sophisticated cyberattacks.
  • Experimental comparisons demonstrate that the proposed scheme offers lower computation and communication costs compared to existing access control schemes.

Conclusions:

  • The developed heterogeneous access control protocol enhances the security and privacy of medical data transmitted via WBANs in IoT environments.
  • The scheme provides a practical and efficient solution for secure remote patient monitoring.
  • This work contributes to the secure integration of WBANs into the broader IoT landscape for healthcare applications.
