Path oriented randomly-generated keys for uncompromising security in MANETs

A MANET is a infrastructure-less and auto configurable network of mobile nodes which are connected without wires. As per proposal of this paper, the communication in a MANET works on set of random keys called KEY1=X+KEY0, KEY2=X+KEY1, KEY3=X+KEY2..KEYN=X+KEYN-1 to establish the connection between nodes and applies to validate the packets. Since there could be a issue of keys length, hence we can enforce the number of hops to be added for key generation after reaching threshold, then generation of keys starts from the beginning. Here all nodes in the network would generate a X-key and appends to the ongoing/flowing key. When a source node initiates communication towards a destination node, the source node will send a packet to a destination via a designated path. The target node and threshold node would be storing a expected key from all its neighbours, when a packet reaches to a target node or threshold node, key of packet and key of target node is compared, if a match is found, then accept the packet as valid one else discard it or deny the communication. This approach would be very helpful to deny the communication of malicious nodes in the MANET. © 2015 IEEE.
