基于EPON网的AES加密电路设计

AES Encryption Circuit Design Based EPON Network

EPON网是基于千兆以太网的无源光网络技术,是光纤接入网的重要解决方案之一,具有良好的市场发展空间。随着广电网络技术的发展,信息安全的重要性日益增加,加密技术也越来越受到关注。AES算法作为现在的主流加密手段,是密码学中的高级加密标准,对它进行学习和运用具有十分重要的现实意义。讨论EPON系统下行传输存在的安全问题,并简单介绍高级加密算法(AES)在EPON系统内的实现方式,其中主要涉及AES原理的分析以及AES算法的硬件实现和功能仿真。

EPON network is based on passive optical network technology Gigabit Ethernet is one of the important fiber access network solutions, has a good market development. With the rapid technology advances radio and television networks, the increasing importance of information security, encryption technology is also increasingly being everyone＇s attention. AES encryption algorithm as a means to mainstream now, and is Cryptography Advanced Encryption Standard, and use it to learn the real meaning is very important. This article discusses security issues downlink EPON system exists, and a brief introduction of the Advanced Encryption Algorithm （AES） in the EPON system implementations. This paper analyzes the main principles involved in AES and AES algorithm in hardware and functional simulation.
