Description
Summary:In the context of the digital age, the importance of information security is increasingly prominent, especially when facing complex network attack methods. SM3, as a password hashing algorithm recommended by the National Cryptography Administration of China, has high security and reliability in applications such as data integrity verification and digital signatures. However, the SM3 algorithm faces challenges of insufficient flexibility and slow encryption speed in practical applications. To address these issues, this study proposes an improved SM3 encryption algorithm. This algorithm enhances the randomness and unpredictability of the algorithm by introducing chaotic mapping and random numbers, effectively improving security. At the same time, the core steps of the algorithm - input expansion and message compression - have been optimized, significantly improving computational efficiency. The experimental results show that the new algorithm achieves a significant improvement in encryption efficiency while maintaining security, providing a new solution for large-scale encryption applications.
