基于面包师变换的应急救援重要信息安全传输技术

A safe transmission technology of important information for emergency rescue based on baker’s transformation

为了满足恶劣环境下应急救援现场通信安全的需求,研制了一种低成本高性能的安全传输应急救援保密信息的技术。先用面包师变换把将要传输的保密信息变换为一堆乱码,达到初级保密的目的。然后,再把该乱码嵌入到一幅风景图像中,基本不改变原图的品质,使人无法判断该幅风景图中是否嵌入了保密信息,达到迷惑攻击者的目的。该技术只需要把算法转换为计算机程序,安装在现有的通信设备上,不需要额外增加硬件设备,就可以实现加密。仿真实验证明:该方法实现加密过程,性价比高。

In order to meet the requirements of emergency rescue communication security in harsh environment,a safe transmission technology of important emergency rescue information with high performance-price patio is developed in the paper.First,the secret information to be transmitted is transformed into a mess of code with baker transform to achieve the purpose of primary confidentiality.Then,the garbled code is embedded into a landscape image,without changing the quality of the original image,making it impossible for people to judge whether the landscape image is embedded with confidential information,so as to confuse the attacker.This technology only needs to write the algorithm into a computer program and install it on the existing communication equipment,no additional hardware is required.The simulation experiment proves that the method given in this paper realizes the encryption process and is cost-effective.
