【摘要】 介绍了基于 Logistic 混沌映射的加密算法原理,提出一种基于该算法的加密/解密模型,并用 VB 完成了图文加密/解密软件设计．实现了在多种图文格式条件下,能够正确识别和显示解密后的图文的功能,克服了只针对单一图文格式加解密的局限性,因此具有很强的通用性．更多还原

【Abstract】 The principle of chaotic encryption algorithm based on Logistic formula is introduced.Then a encryption/ decryption model is proposed.A software is designed by using the development tools of visual basic.The encryption/ decryption of multi-format images and files is realized,which can recognize and display the images and files correctly after decryption.The limitation of encryption/decryption for single-format image or file is overcomen.The strong feasibility in practice is showed.更多还原
