摘要
为了保护10G EPON中下行数据的安全,基于10G EPON的测距原理,在加密算法中嵌入时戳信息。改进的安全方案的密钥和密文可随时间变化,同时OLT和ONU可利用时戳在动态测距过程中安全交换密钥,实现密钥的更新同步。实验结果证明了该方案的有效性。
In order to protect downstream traffic in 10G EPON from eavesdropping, the timestamps used in ranging are added into the eneryption algo- rithm. Therefore, the cipher key and text vary with time. Meanwhile, the secure key exchange can be achieved during the dynamic ranging process, to safely update and synchronize the cipher key. The experimental results prove the validity of this scheme.
