摘要
波分复用系统是将多个独立的光波耦合复用到一根光纤中传输,从而更有效地提供带宽,让IP、ATM、SDH等数据通过统一的光纤层传输的系统。波分复用系统在改善网络性能的同时,也给网络的安全带来了一定的隐患。文中针对波分复用(WDM)自身特点及所面临的安全威胁,提出基于WDM的加密技术研究思路,为实现对WDM/OTN/ASON网络综合数据业务的安全保密奠定了基础。
Wavelength division muhiplexing（WDM） system couples multiple independent light waves into one optical fiber for transmission, and thus provides effective bandwidth and uniform optical fiber layer for transmission of data information, such as, IP, ATM, SDH and so on. WDM system improves network performances, while brings hidden troubles to network security. Aiming at WDM＇s characteristics and security threats, a research idea of encryption techniques for WDM is proposed in this paper, which lays a theoretic foundation for implementing integrated data-service security of WDM/OTN/ASON network.
