多媒体环境下语音保密体制的研究与实现

RESEARCH AND REALIZATION OF AUDIO CRYPTOSYSTEM IN MULTIMEDIA ENVIRONMENT

本文提出了一种在多媒体环境下适合于语音保密的并行ｍ序列随机抽样密码算法，基于该算法设计一个多媒体语音保密系统模型，系统包括语音的录音、放音、集成、效果修饰、加密、解密等功能。

The paper proposes a cryptography algorithm of parallel m _sequences random sampling sequence _code. The cryptography algorithm is completed quickly. Multimedia audio cryptosystem model is designed based on this cryptography algorithm. The model includes the functions of recording、 playing、editing、encrypting、decrypting、key generating.
