Sensor networks are composed of a large number low power sensor devices. For secure communication among sensors, secret keys must be established between them. Recently, several pairwise key schemes have been proposed for distributed networks. These randomly select set from pool and install the in memory each sensor. After deployment, sensors can up by using preinstalled keys. Due to lack tamper-resistant hardware, vulnerable node capture attacks. The information gained captured nodes used compromise uncompromised sensors. Du et al. [1], Liu Ning [2] use known deployment reduce requirements mitigate consequences attack. Our analysis shows that assumption random is too <i>weak</i>. An <i>intelligent</i> attacker selectively get more with less efforts. In addition selective attack, all recent proposals fabrication which an fabricate new manipulating compromised then deploy fabricated into system. To counter these attacks, we propose grid-group scheme uses information. Unlike al., uniformly area; instead distributing sensor, systematically distribute structured pool. performance our requires resilient attack
