Abstract

In 1997, the US National Science Foundation recognized the need to unite research communities together to solve mutual problems, overcome challenges, future development and practical applications of cryptography and error correction coding. Recent works in this area are connected with turbo codes, which have a special ability to provide error correction characteristics of the information transmission close to theoretically obtained values. Besides, they are used for television (DVB-RCS, DVB-RCT), wireless local networks (WiMAX), software-defined radio systems, mobile (3G, 4G, Inmarsat) and space (CCSDS) communications etc. In this article is presented the crypto coding system based on turbo codes with secret keys used by interleavers. All calculations are performed during data encoding, which reduces the computational complexity of data pre-encryption. The necessary mathematical apparatus was presented, the security level of the communication system was estimated, a simulation of the error correction characteristics was performed, and multimedia information was processed. The working characteristics of the classical and proposed turbo codecs do not differ statistically. The results can be used in communication systems for various functional purposes.

基于带有密钥的涡轮编码的密码编码系统

1997 年，美国国家科学基金会认识到有必要将研究界联合起来，共同解决密码学和纠错编码的共同问题、克服挑战、未来发展和实际应用。该领域的最新研究成果与涡轮编码有关，涡轮编码具有提供接近理论值的信息传输纠错特性的特殊能力。此外，它们还用于电视（DVB-RCS、DVB-RCT）、无线局域网（WiMAX）、软件定义无线电系统、移动（3G、4G、Inmarsat）和空间（CCSDS）通信等。本文介绍的加密编码系统基于带有交织器使用的密钥的涡轮编码。所有计算都在数据编码过程中进行，从而降低了数据预加密的计算复杂度。文章介绍了必要的数学装置，估算了通信系统的安全等级，对纠错特性进行了模拟，并处理了多媒体信息。经典的和拟议的涡轮编解码器的工作特性在统计上没有差异。研究结果可用于各种功能的通信系统。
