Abstract: As a key element in secure wireless sensor networks, routing protocol security constitutes a potential block to impending wide deployment of Wireless sensor networks. Due to its network peculiarities, designing security routing protocol is a challenge in these networks. Various attacks against wireless sensor network routing protocols was listed, and security routing issues were analyzed from two aspects: requirement analysis and current research status, meanwhile, the propositional design considerations and possible directions were presented for future research.

Key words: wireless sensor networks, security, routing protocol
