随着无线技术在电力行业应用越来越广,其安全问题也愈发突出,由于无线网络易受到安全攻击,同时设备制约也给安全服务的实现带来一定困难。6Lo WPAN技术正在演变为一种无线网络引领技术,提出一种从上至下的接入控制方法,在一定程度上提高基于6Lo WPAN的无线网络的安全性能。 As wireless technology becomes more and more widely used in the power industry, its security issues become more and more prominent. Because wireless networks are vulnerable to security attacks, device constraints also bring some difficulties to the realization of security services. 6Lo WPAN technology is evolving into a wireless network leading technology, and proposes a top-down access control method to improve the security performance of the 6Lo WPAN-based wireless network to a certain extent.
