Recent development of sensor and computer technology enabled WSNs (wireless sensor networks) to be expanded. To conserve power from each sensor, intermediate nodes should aggregate results from individual sensors. However, it can make it that a single compromised sensor can render the network useless, or worse, mislead the operator into trusting a false reading. In this paper, we propose a protocol...
WSNs, since the attacks, such as jamming or eavesdropping without physical access, easily occur, security is one of the important requirements for WSNs. The key pre- distribution scheme, recently being researched for advances of security in WSNs, distributes keys with probability with the use of q-composite random key pre-distribution method, but there is a high probability that there is no key shared...
