一种新的全光同步方案设计与验证摘 要：全光异或加解密系统是解决光网络目前所面临的“速率瓶颈”和安全威胁问题的一种有效途径，而保证加解密系统可靠高效工作的前提是实现全光同步.文章简要分析了现有全光同步方案的局限性，针对全光异或加解密系统中的密码同步问题,设计了一种新的全光同步方案，将具有相同光功率的同步信号和密文数据进行波分复用并都通过经典信道进行传送，推导出了光纤信道传播时延差公式,通过对密文数据进行相应的延时控制来实现其与解密密钥之间的密码同步功能，利用OptiSystem7.0 分别对 10Gbit/s 和 40Gbit/s 的全光异或加解密速率进行仿真实验,验证了该全光同步方案的可行性.关键词：光网络；全光同步；全光异或加解密；波分复用；色散;光纤传播时延差中图分类号：TN913。7A New All—Optical Synchronization Scheme Design and VerificationAbstract: All—optical XOR encryption and decryption system is an effective way to solve the “speed bottleneck” problems and security threats currently encountered by optical networks， and the premise to ensure the system to work reliably and efficiently is to achieve all—optical synchronization. The limitation of the existing all—optical synchronization scheme is analyzed briefly in this paper。 For the password synchronization problem of all-optical XOR encryption and decryption system ， a new all—optical synchronization scheme is designed ， the synchronization signal and ciphertext data with same optical power are transmitted through the classical channel. The fiber channel propagation delay difference equation is deduced， the password synchronization function between ciphertext data and decryption key is achieved through the corresponding delay control to ciphertext. The simulation experiments of all—optical XOR encryption and decryption speed at 10Gbit/s and 40Gbit/s are did respectively through OptiSystem7.0， that tests the feasibility of the all—optical synchronization scheme。Keyword...
