EPON中基于时间标签的加密方案研究

Research of the encryption scheme based on timestamp in EPON

提出了一种基于时间标签的下行加密方案。该方案将时间标签与AES算法相结合生成密钥,对下行数据进行加密。同时该方案利用时间标签的同步实现密钥的动态更新和同步,从而保证了传输数据的安全性。实验结果证明了该方案的有效性。

A downstream encryption scheme based on timestamp is introduced. This scheme combines times- tamp with AES algorithm to carry on the encryption to the downward data. Meanwhile, it uses the synchro- nization oftimestamp to dynamically update keys and sync them, thus, the safety of data is promised. The ex- periment results indicate the validity of this scheme.
