EPON中块加密方案的研究

Study of block encryption scheme in EPON

以太网无源光网络(EPON)被认为是一种最佳的光纤接入网技术。由于它是一个点到多点的网络结构,所以存在一定的安全问题。文章针对EPON中存在的安全问题,介绍了一种计数器模式下的块加密方案,针对加密输入值和加密计数器的校准中存在的问题进行了详细研究,并且给出了相应的解决方案。

Ethernet passive optical network （EPON） is considered as one of the best fiber-optic access network technology, because it is a multipoint network structure, so there is a certain security problems.The paper presents a counter mode of block encryption scheme,and carded out a detailed study for the problems in the encrypted input values and encryption counter calibration, and gives the corresponding solution.
