    Only one single key is saved in the nodes ' memory and once enforced in the network, there is no requirement for a node to perform key exchange or key discovery, however, all the nodes in communication coverage area can transfer messages employing the key which they already share. On the other side, this strategy suffers a serious disadvantage that adjustment of a single node would lead compromise of the whole network by the shared key. Hence it fails in offering the basic secure need of a…

    1.2. Previous Work The first symmetric key schemes for keyword search over encrypted data are proposed in [27]. The authors consider a setting in which the sender of file encrypts each word of a file separately. Goh [15] proposed a method for secure index using Bloom filters and introduced the notion of semantic security against adaptive chosen-keyword attacks. Determining whether a file contains a keyword can be done securely in constant time. In the public key setting, Boneh et al.[5] first…
