Q. Attacks on wireless network

WSN are vulnerable to attacks which compromise the integrity of the WSN nodes by decreasing the nodes' fault tolerance capabilities, data distribution, and multipath routing of packets. Hu, Ziobro, Tillett and Sharma, Karlof  and Wagner, and Kaplantzis that Sybil attacks as being critical in WSN because the attacks compromise the integrity of the network by ensuring broadcast packets based on direct vs. indirect communication, stolen vs. fabricated identities are undetected. Eschenauer and Gligor and Gautam, Lee, Pyun and Jae-Young show that Sybil attacks are propagated directly or indirectly using misbehaving nodes, voting, routing, data aggregation, and distributed storage techniques. A detailed study on solutions based on direct validation, indirect validation, resource testing are deficient countermeasures against such attacks. Liu, Ning and Li questions and affirms that modern techniques which depend on radio resource testing, post verification, RSSI based detection scheme, registration, code attestation, and random key distribution do not provide complete security to a WSN underscoring the need for a triple key management scheme.
