The primary goal of current routing protocols for wireless sensor network (WSN) is to improve the energy efficiency while guarantee the required communication. Therefore, Most protocols do not take security into consideration. As a result, many potential security problems exist in such protocols that they may be vulnerable to various attacks and cannot be applied to many fields. An illustration of various attacks on routing protocols is presented first. Then the current research status of security routing protocol was summarized. Finally, possible directions in future research were presented.
