摘要：—The severe constraints and demanding depl oyment environments of wireless sensor networks make s ecurity for these systems more challenging than for conventional networks. However, several properties of sensor networks may help address the challenge of building secure networks. T he unique aspects o f sensor networks may allow novel defenses not available in conventional networks. In this paper, we investigate the security related issues and challenges in wireless sensor networks. We identify the security threats, review proposed security mechanisms for wireless sensor networks
