摘要:

为了维护光网络安全,亟需研究部署能够有效处理高速光信号的光子防火墙,以替代现有的高能耗的电子防火墙。在介绍光子防火墙原理的基础上,基于相关运算和逻辑门2种主要实现方式综述了模式匹配技术,对比了各匹配系统的优劣,并总结了全光逻辑门的实现方法。最后,展望了全光模式匹配研究的下一步方向与发展趋势,即更高效的系统结构和响应速度更快的非线性器件。分析表明,基于全光模式匹配的光子防火墙在网络安全中具有良好的应用前景。

Abstract:

In order to maintain the security of optical network,it is urgent to research and deploy photonic firewall which can effectively process high-speed optical signals to replace existing electronic firewall which consumes high energy.After a brief review of the principle of photonic firewall,the pattern matching technology based on correlation operation and all-optical logic gates were summarized,and the matching systems was compared according to their advantages and disadvantages.Besides,the realization methods of all-optical logic gates were introduced.Finally,the next research direction and development trend of all-optical pattern matching were prospected:more efficient system structure or non-linear devices with faster response speed.The survey shows that photonic firewall based on all-optical pattern matching has a good application prospect in network security.

Key words: photonic firewall, pattern matching, semiconductor optical amplifier, highly nonlinear fiber
