Abstract
With the rapid development of wireless communication technology, issues regarding communication security have become increasingly prominent. As a core means to ensure information security, the application of encryption algorithms in wireless communication is of great significance. This study aims to explore efficient encryption algorithms suitable for modern wireless communication environments and analyze their performance and security. By comparing the advantages and disadvantages of traditional symmetric and asymmetric encryption algorithms and considering the practical requirements of wireless communication, a hybrid encryption scheme based on an improved AES algorithm is proposed. This scheme significantly enhances encryption efficiency while ensuring the security of data transmission. The research employs a combination of theoretical analysis and simulation experiments to verify the adaptability and stability of the proposed scheme in complex wireless environments. Experimental results indicate that the improved encryption algorithm demonstrates superior performance in terms of key management, computational overhead, and resistance to attacks. The primary contribution of this study lies in proposing an encryption mechanism that balances security and efficiency, providing new insights and technical support for the security protection of wireless communication. Additionally, it lays a foundation for future research in related fields.
