CENTERA: A Centralized Trust-Based Efficient Routing Protocol with Authentication for Wireless Sensor Networks

Abstract

In this paper, we present CENTERA, a CENtralized Trust-based Efficient Routing protocol with an appropriate authentication scheme for wireless sensor networks (WSN). CENTERA utilizes the more powerful base station (BS) to gather minimal neighbor trust information from nodes and calculate the best routes after isolating different types of “bad” nodes. By periodically accumulating these simple local observations and approximating the nodes' battery lives, the BS draws a global view of the network, calculates three quality metrics—maliciousness, cooperation, and compatibility—and evaluates the Data Trust and Forwarding Trust values of each node. Based on these metrics, the BS isolates “bad”, “misbehaving” or malicious nodes for a certain period, and put some nodes on probation. CENTERA increases the node's bad/probation level with repeated “bad” behavior, and decreases it otherwise. Then it uses a very efficient method to distribute the routing information to “good” nodes. Based on its target environment, and if required, CENTERA uses an authentication scheme suitable for severely constrained nodes, ranging from the symmetric RC5 for safe environments under close administration, to pairing-based cryptography (PBC) for hostile environments with a strong attacker model. We simulate CENTERA using TOSSIM and verify its correctness and show some energy calculations.

Wireless Sensor Network Technology Based on Security Trust Evaluation Model

“…In that model, the node trust calculation, the fuzzy partition and the fusion are carried out successively through the trust factor, the fuzzy set and the D-S evidence theory [9][10][11], with information security improvement in this paper.…”

Referencing Tool for Reputation and Trust in Wireless Sensor Networks

“…Data trust is a value which depends on the maliciousness, cooperation and competence of a node [15]. When a message is received by a node in the network, it is expected that the node will send the same unaltered message to other nodes in the network.…”

Trusted Tree-Based Trust Management Scheme for Secure Routing in Wireless Sensor Networks

“…At the Sink, it firstly verifies RDP and then calculates the total cost of the routing path by using (17). After the Sink receives a few routing discovery packets from node , it makes the routing decision by using (19). The path with the least cost is selected as the optimal path.…”

“…The nodes' trust value and the best routes are calculated for excluding the malicious nodes. Improving on the previous CENTER, CENTERA [19] includes an appropriate authentication scheme, and the base station gathers minimal neighbor trust information from the nodes. Although the base station can calculate and evaluate the trust value of the nodes by the global view of the network, the accuracy of trust metrics about the distributed nodes needs to be improved.…”

“…And the distance between any two nodes is more than 7 meters. The ID of node is orderly numbered by their distance to the Sink from near to Receiving Node adds its own information and rebroadcasts RDP; (6) else (7) Receiving Node drops RDP; (8) end if (9) end while (10) By using (17), the Sink computes the cost for the current route of the RDP; (11) Store the current RDP and its cost into Ω SourceNode → Sink ; (12) if Ω SourceNode → Sink is FULL; (13) By using (19), select the one with the least cost; (14) Sends the REP back to the Source Node over the selected route; (15) Generates the RER, and broadcasts the RER; (4) if (Monitoring Node == Source Node AND Monitored Node == Next Hop) (5) Deletes the route, and invokes Algorithm 1(a); (6) else if (Monitored Node == Next Hop) (7) Deletes the route; (8) end if; (9) end if; (10) while (Receiving Node ̸ = Source Node) (11) if (Sending Node == Next Hop OR Monitored Node == Next Hop) (12) Deletes the route; (13) end if; (14) Broadcast the RER; (15) end while; (16) far. Among the total number of the nodes in the experiment, 10 percent nodes are selected as the malicious nodes.…”
