Wireless sensor networks (WSNs) have been deployed largely due to recent advances in wireless communication technologies. These sensors may be deployed in adverse or even hostile environments so they should consider security issues in their communications. In this paper we proposed sectorized location dependent key management (SLDK) based on Anjum's LDK algorithm in which generation of link securing...
In wireless sensor networks, the majority of key managements use the random key predistribution mechanism which is based on the probability model. Thus, an adversary can easily get the keys between any two non-compromised nodes by compromising some number of nodes. If an adversary gets the keys, he can modify or insert messages into the communication channels. These kinds of attacks are very critical...
