File Encryption System Based on the Hybrid LPC Coefficient and AES Algorithm

摘要

At present, academic research on information security is getting deeper and wider. In this paper, the LPC coefficient and the speech waveform characteristics are mixed to form the hybrid LPC coefficient. The hybrid LPC is then used as the secret key of the AES algorithm in the file encryption system. The system is designed based on VS2012, all the files can be encrypted and decrypted by the system using the voice hybrid LPC key, and the system performance is relatively stable.
