Abstract

The paper describes an encryption system developed in a project oriented study course in the fall of 1997 at Linkoping University, Sweden. The course assignment was to develop a short-range wireless communications system for simplex transmission of video data, e.g. from a surveillance camera. The encryption system was part of this system. Radio sender and receiver hardware were provided while software was developed on Sun Sparc computers. The goal was to create a system capable of continuous real time operation. Requirements were that the communications channel should provide confidentiality as well as authenticity of the video data, thus requiring cryptography. The main challenge was to design an encryption system that propagates as few errors as possible which are introduced by radio transmission. The developed encryption system uses RSA for encrypting session keys and an alternating stop-and-go stream cipher for bulk data encryption.

一种用于缺陷数据传输的公开密钥加密系统

本文描述了在1997年秋季瑞典林雪平大学的一个面向项目的研究课程中开发的一个加密系统。课程的任务是开发一种短距离无线通信系统，用于单纯传输视频数据，例如来自监控摄像机的视频数据。加密系统是这个系统的一部分。无线电发送和接收硬件由Sun Sparc提供，软件则在Sun Sparc计算机上开发。目标是创建一个能够连续实时操作的系统。要求是通信信道应提供视频数据的保密性和真实性，因此需要密码学。主要的挑战是设计一个加密系统，使其传播尽可能少的错误，这些错误是由无线电传输引入的。所开发的加密系统使用RSA对会话密钥进行加密，使用交替的走走停停流密码对大容量数据进行加密。
