摘 要: 本文在虚拟光学数据加密理论模型的基础上 ,研究一种并行电子系统实现方法 .该系统利用TMS32 0C6 70 1浮点DSP(DigitalSignalProcessor)实现具有多重锁、多重密钥的高密级多媒体数据加密系统 .该系统具有安全性高、加 /解密速度快、实时性好、适用范围宽等优点 ,可用于多种媒体信息如文本、图像、语音、视频等的加 /解密 . In this article,we investigate an implementation scheme of virtual-optics based data encryption system.With such a scheme,we make use of a high performance floating-point Digital Signal Processor (DSP) to accomplish a design of multiple-locks and multiple-keys multimedia information hiding system.This scheme balances the advantages of higher security strength in the methodology of optical data processor and the high flexibility in the methodology of electronic data processor.The scheme reported in this article can be applied to the data encryption for various digital media such as text,image,or even audio signal.
