A State Secret Algorithm-Driven Encryption Scheme with Parallel SSL for Secure Data Transmission in Railway Freight E-Bill System

For the security of railroad freight electronic ticket data exchange, this paper proposes a security scheme for railroad freight electronic ticket exchange based on hybrid state secret algorithm combined with TOTP dynamic encryption technology. In the data storage level, the scheme utilizes SM2 and SM3 algorithms to encrypt sensitive data and combines with TOTP dynamic encryption technology, which effectively improves the security and anti-attack ability of the data. At the data transmission level, the parallel SSL and SM2 two-way handshake mechanism is used to ensure secure and efficient data transmission. Through experimental verification, this solution has significant advantages in protecting the data security of railroad freight e-tickets, and provides new technical ideas for data security storage in the railroad freight industry.
