Signal and System01:26

Signal and System

1.5K
A signal x(t) is a set of data or a time function representing a variable of interest. Signals typically convey information about a phenomenon, such as atmospheric temperature, humidity, human voice, television images, a dog's bark, or birdsongs. More generally, a signal can be a function of more than one independent variable. For instance, images depend on horizontal and vertical positions and can be regarded as two-dimensional signals. However, this text will focus on one-dimensional...

Asymmetric Lipid Bilayer01:35

Asymmetric Lipid Bilayer

9.5K
Biological membranes show uneven distribution of different types of lipids in the inner and outer layers, resulting in transverse asymmetric membranes. The treatment of the erythrocyte membrane with the enzyme phospholipase confirmed the asymmetric nature of the lipid bilayer. The enzyme hydrolyzes lipids into fatty acids and hydrophilic groups. The phospholipase acts only on the outer layer of the membrane, while the inner layer remains intact. The phospholipase treatment resulted in 80%...

Barriers to Effective Communication II01:21

Barriers to Effective Communication II

4.5K
The barriers to effective communication also include cultural barriers, semantic barriers, gender barriers, and time constraints.
Cultural barriers:
Differences in values, beliefs, religion, knowledge, and tradition can significantly impact communication. Awareness of nonverbal cues is critical, especially when conversing with a patient from a different culture. What appears appropriate in one culture may be inappropriate in another.
Semantic barriers:
As a result of their tendency to use...

Communication01:28

Communication

9.3K
Sharing information, concepts, and emotions to foster mutual understanding is communication. The sender, recipient, and transaction must be considered in this manner. The sender is the person who shares the message, the recipient is the person who receives and understands the message, and the transaction is the method used to deliver the message and the variables that affect the communication's context and surroundings. The nurse-client connection is built on therapeutic communication.

Communication01:03

Communication

8.5K
Communication between two animals occurs when one animal transmits an information signal that causes a change in the animal that receives the information. Organisms communicate with one another in a host of different ways. Signals can be auditory, chemical, visual, tactile, or a combination of these. Communication is a critical behavioral adaptation that promotes survival, growth, and reproduction.

Neuronal Communication01:28

Neuronal Communication

2.9K
Neurons, the fundamental units of the brain and nervous system, communicate through complex electrochemical signals that underpin all cognitive and bodily functions. This communication is primarily facilitated by a process involving the generation and propagation of an action potential along the axon of the neuron. When the internal electrical charge of a neuron surpasses a certain threshold, an action potential is triggered. This rapid change in voltage travels swiftly along the axon to the...

Area of Science:

  • Cryptography and Network Security
  • Embedded Systems Security
  • Applied Cryptography

Background:

  • Interconnected, latency-sensitive systems demand efficient cryptographic solutions for authenticated confidentiality on constrained hardware.
  • Existing cryptographic frameworks may not adequately balance security, performance, and cost for resource-limited environments.
  • Need for robust security primitives with predictable performance characteristics.

Purpose of the Study:

  • To present CryptoShield, a multilayer cryptographic framework designed for constrained hardware.
  • To demonstrate the effectiveness of composing Elliptic Curve Diffie-Hellman (ECDH), AES-GCM, and Elliptic Curve Digital Signature Algorithm (ECDSA).
  • To evaluate performance and security improvements through specific design choices like key separation and entropy-enhanced salting.

Main Methods:

  • Composed ECDH for key agreement, AES-GCM for authenticated encryption with associated data (AEAD), and ECDSA for origin authentication.
  • Implemented PBKDF2-HMAC with entropy-enhanced salting for key derivation and optional XOR pre-processing for de-biasing.
  • Incorporated elliptic-curve optimizations like scalar-multiplication improvements and structure-preserving mappings.
  • Simulated CryptoShield using KDD Cup 1999, UNSW-NB15, and IoTID20 traffic profiles.

Main Results:

  • Achieved encryption and decryption latencies under 10 ms (e.g., 7.9 ms on IoTID20) with throughput up to 5010 ops/s.
  • Quantified high authentication strength with MAC entropy reaching 243 bits and derived key entropy at 256 bits.
  • Demonstrated improved authentication security and system performance compared to baseline methods like EGCM, ANAF, and ASMD.

Conclusions:

  • CryptoShield provides a secure and efficient cryptographic solution for interconnected, latency-sensitive systems on constrained hardware.
  • Partitioning cryptographic primitives, entropy-based key derivation, and curve-level optimizations significantly enhance security and performance.
  • The framework meets the demands for high assurance and speed in performance-critical applications.
