Summary
This study introduces a new Software Defined Network-based Anonymous Communication Tracking (SACT) model. SACT enhances anonymous tracking by integrating network watermarking, improving scalability and anti-detection capabilities for covert communication.
Area of Science:
- Computer Science
- Network Security
- Information Theory
Background:
- Traditional anonymous tracking faces limitations in scalability and reusability due to device deployment in network watermarking.
- Software Defined Networking (SDN) offers enhanced flexibility through control and data plane separation, presenting opportunities for improved tracking mechanisms.
Purpose of the Study:
- To propose a novel anonymous communication tracking model, SDN-based Anonymous Communication Tracking (SACT), leveraging SDN architecture.
- To enhance the anti-detection capabilities and overall effectiveness of anonymous tracking in network environments.
Main Methods:
- Integration of network watermarking techniques within an SDN framework.
- Combination of IP time hidden channel and symbol expansion technologies for covert communication.
- Implementation of a hopping protection mechanism to bolster watermark security against detection.
Main Results:
- SACT demonstrated excellent detection rates and low bit error rates across various simulated network environments.
- The model effectively established communication relationships between parties.
- SACT successfully addressed the deployment challenges inherent in traditional anonymous tracking systems.
Conclusions:
- SACT provides a scalable and reusable solution for anonymous communication tracking within SDN architectures.
- The proposed model significantly improves the availability and anti-detection capabilities of covert communication.
- SACT offers a robust method for determining communication relationships while maintaining anonymity.

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...

Frequency response analysis in electrical circuits provides vital insights into a circuit's behavior as the frequency of the input signal changes. The transfer function, a mathematical tool, is instrumental in understanding this behavior. It defines the relationship between phasor output and input and comes in four types: voltage gain, current gain, transfer impedance, and transfer admittance. The critical components of the transfer function are the poles and zeros.

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...

Since the early 2000s, computer-mediated communication (CMC) has grown rapidly, playing a crucial role in self-development. A key distinction between CMC and real-life interactions is the lack of a physically present partner. This absence makes non-verbal cues such as facial expressions, body language, and paralinguistic signals unavailable in CMC platforms like email, instant messaging, or social media. The lack of these cues can create ambiguity and complicate how feedback is interpreted.The...

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.

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.
