Summary
This study introduces a secure log transmission system using a data diode to prevent threats. The system ensures data integrity and confidentiality through unidirectional flow and synchronized encryption, mitigating replay attacks.
Area of Science:
- Computer Science
- Network Security
Background:
- Standard log transmission protocols lack robust segregation from network threats.
- Ensuring log data integrity and confidentiality is critical in many regulated environments.
Purpose of the Study:
- To propose a secure log transmission system utilizing a data diode.
- To develop an affordable and reproducible solution for log network segregation.
Main Methods:
- Implementation of a data diode for unidirectional data flow.
- Development of a synchronized encryption protocol to prevent replay attacks.
- Adaptation of an encryption algorithm for resource-constrained devices.
Main Results:
- The system effectively segregates log networks, preventing unauthorized access and eavesdropping.
- The encryption protocol ensures data integrity and confidentiality.
- The proposed encryption algorithm is suitable for low-power devices and produces random-looking output.
Conclusions:
- The developed system provides a robust and affordable solution for securing log networks.
- The solution is easily reproducible, aiding compliance with legal logging requirements and preventing log tampering.
