Protein Networks

4.5K
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,...

The Mechanics of (Poro-)Elastic Contractile Actomyosin Networks As a Model System of the Cell Cytoskeleton

1.2K
In this work, an in vitro reconstitution approach is employed to study the poroelasticity of actomyosin gels under controlled conditions. The dynamics of the actomyosin gel and the embedded solvent are quantified, through which the network poroelasticity is demonstrated. We also discuss the experimental challenges, common pitfalls, and relevance to cell cytoskeleton...

Wind tunnel tests are useful in the design of vehicles and structures that are subjected to airflow during their use. Wind tunnel data are generated by applying a controlled air flow to a model of the object being studied. The test model usually has a similar geometry but is a smaller scale compared to the full-sized object. To ensure accurate and useful data is collected...

Area of Science:

  • Computer Science
  • Network Security

Background:

  • OpenFlow protocol has limitations in match field capacity and lacks robust security mechanisms for packet forwarding in software-defined networks (SDN).
  • Existing solutions struggle with flexible secure tunnel establishment, leaving data vulnerable to tampering, theft, and forgery.

Purpose of the Study:

  • To propose P4Sec, a novel packet security tunnel forwarding mechanism for SDN.
  • To address the limitations of OpenFlow by providing data source authentication, integrity verification, and confidentiality protection.
  • To enable flexible and secure tunnel establishment in SDN environments.

Main Methods:

  • Leveraging the P4 language for programmable data plane packet forwarding.
  • Developing a P4Sec security tunnel mechanism to prevent malicious network behaviors.
  • Implementing packet routing and forwarding based on gateway identity.
  • Constructing a P4Sec prototype system using the BMv2 software switch.

Main Results:

  • Experimental analysis validated the effectiveness of the P4Sec mechanism.
  • The P4Sec security mechanism ensures the authenticity, integrity, and confidentiality of forwarded data.
  • The mechanism meets the secure forwarding requirements for data packets in SDN.

Conclusions:

  • P4Sec provides a robust solution for enhancing network security in software-defined networks.
  • The proposed mechanism effectively mitigates risks associated with data tampering, stealing, and forgery.
  • P4Sec demonstrates the feasibility and effectiveness of programmable data planes for secure network communications.
