Analysis of information transmission coding algorithm in railway communication system security scheme

Abstract

The rapid advancement of railway communication systems necessitates robust security mechanisms to ensure reliable and secure data transmission. It explores the design and analysis of an information transmission coding algorithm (ITCA) tailored for railway communication system security schemes. Specifically, it focuses on three key areas: error correction coding, encryption mechanisms, and authentication protocols. The proposed scheme integrates the techniques in a layered manner, ensuring robust protection against security threats such as data interception, tampering, and unauthorized access, while also optimizing performance for real-time railway communication requirements. Hamming code is used to detect and correct errors, ensuring that the received data is as accurate as the original message. For encryption, the Hybrid RSA-Blowfish (HRB) algorithm is utilized. It combines the strength of RSA for key exchange and Blowfish for fast, secure data encryption, providing robust protection against unauthorized access during transmission. Password-based authentication is implemented to verify and ensure message integrity and non-repudiation. The methodology demonstrates its effectiveness through simulation, showing a significant reduction in error rates, enhanced security with minimal computational overhead, and improved overall system performance. Key performance metrics, such as throughput (50 Mbps), latency (7 ms), and data integrity (96.3%), were improved demonstrating that the proposed approach balances security and efficiency in the Python platform. The methodology demonstrates its effectiveness through simulation and evaluation, showcasing a secure and reliable approach to safeguarding railway communication systems.
