Protecting Data Aggregation from Compromised Nodes in Wireless Sensor Network

Message aggregation can be used to reduce the communication overhead in a network where many messages have the ldquosamerdquo content, but sensor networks is vulnerable to node compromising attacks. In this paper, we propose an all-around method to protect data aggregation against compromised nodes in wireless sensor networks. We use lightweight cryptography method to resist forge and juggle while the security is proofed by BAN logic language.
