/ / / /浅谈指挥自动化系统中多媒体的安全分析Introduction to multimedia in command automation system safety analysis 指挥自动化系统是指在军队指挥系统中，综合运用以电子计算机为中心的各种技术设备，完成军事信息搜集、传送、处置自动化，保证对军队和武器施行指挥与控制的人 机系统。美国称为指挥、控制、通讯和情报系统，简称C4I。树立指挥自动化系统的目的是进步军队指挥和管理效能，从整体上加强军队战役力。第二次世界大战以后，随着武器系统和计算机技术的开展,特别是导弹、核武器的呈现,对军队指挥提出了更高的请求，促使指挥手腕朝着现代化、自动化方向开展。Command automation system is to point to in the military command system, the integrated use of the electronic computer as the center of all kinds of technical equipment, complete military information collection, transfer, disposal automation, guarantee the enforcement of troops and weapons command and control of the man - machine system. America is called the command, control, communications and intelligence systems, hereinafter referred to as C4I. Set command automation system is the purpose of the progress the army command and management efficiency, strengthen the army battle force as a whole. After the second world war, with the development of the weapon system and computer technology, especially the present of missiles, nuclear weapons, the army command put forward higher request, to command the wrist carried out in the direction of modernization and automation. 所谓媒体是指承载信息的载体。依照ITU-T倡议的定义，媒体可分为5种：觉得媒体、表示媒体、显现媒体、存储媒体和传输媒体。觉得媒体指的是用户接触信息的觉得方式。表示媒体则指的是信息的表示方式。显现媒体是表现和获取信息的物理设备。存储媒体是存储数据的物理设备。传输媒体是传输数据的物理设备。Media refers to the bearing carrier of information. According to the ITU - T initiative, the definition of media can be divided into five kinds: think media appeared, said media, media, storage and transmission media. Think media refers to the user contact information way of think. Said the media refers to the representation of information. Show is media performance and the physical device to access information. Storage media is the physical devices to store data. Transmission media is the physical equipment to transmit data. 多媒体技术是指以数字为根底，可以对多种媒体信息停止采集、编码、存储、传输、处置和表现，综合处置多种媒体信息并使之树立起有机的逻辑联络，集成一个系统并能具有良好交互性的技术。普通来说，“多媒体”指的是一个很大的范畴，指的是和信息有关的一切技术与办法进一步开展的范畴。 指挥自动化系统中多媒体平安剖析 指挥自动化系统中视频信息的平安剖析，由于视频信息传输的数据量很大，并且视频信息传输过程中有价值的信息不是很多，同时还要对其停止实时处置，所以，视频信息的传输不同于其它的传输媒体，它具有一定的特殊性。在视频信息停止平安处置是十分有必要的。Multimedia technology refers to digital root, can stop for a variety of media information collection, coding, storage, transfer, disposal and performance, comprehensive treatment of a variety of media contact information and set up organic logic, a system integration technology and has good interactivity. Ordinary, multimedia refers to a large category, and information is all about technology and the way to further. Multimedia in command automation system, analyze video information in the command automation system of peace, because of the video information transmission data volume is large, and video information transmission process is not a lot of valuable information, as well as to stop the real-time disposal, therefore, transmission of video information transmission is different from other media, it has a certain particularity. Stop the safe disposal of the video information is very necessary. 本文主要从以下方面对指挥自动化系统中视频信息的平安停止剖析。高平安性，此特性主要针对信息的复原而言，使那些用不合理手腕或者非法手腕的人很难对对信息停止复原。藏匿性，在发送端的加干扰系统中，对其所加扰的图像或声音、数据要有充沛的失密性。 This article mainly from the following aspects of command automation system of video information safe stop profiling. Gao Pingan sex, this feature is mainly for information recovery, make those who use is unreasonable or illegal wrist wrist recovery is very difficult to stop for information. Sex, hidden on the sending side and interference in the system, the scrambling image or sound, the abundant data should be compromised. 质量复原性，在接纳端关于解干扰系统后的图像或声音，与没有被加干扰的图像或声音相比时泰安太阳能，质量优劣化应在允许范围之内。 指挥自动化系统中视频信息的平安的处理计划 基于流式加密的准绳，基于流式加密的算法在数字电视中被普遍应用。对指挥自动化系统中视频信息停止流式加密算法的详细做法为：对指挥自动化系统中的视频、音频以及辅助数据停止加扰处置。在发送端依托伪随机码发作器产生的伪随机码和原始数据做XOR运算土工膜，就得到加扰的视频和音频数据。Quality resilience, on acceptance about solve the jamming system images or sounds, compared with no added interference image or sound, quality should be within the scope of the permit. Command automation system of safe handling of the program is based on streaming video information encryption of the criterion, based on the streaming encryption algorithm is widely used in digital TV. Stop streaming video information in the command automation system encryption algorithm in detail as follows: the command automation
