“…The amount of data attributes that can be associated with each sensor relies on the size of the Wireless(W) Sensor(S) Network(N) that can improve the network connectivity. Two types of pool based [12] polynomial key allocation with the Paillier Cryptosystem Algorithm [14], significantly improving network flexibility for wireless(W) network(N) replication attacks. Keeping communication costs intact indicates that the creation of encrypted keys and decoding times is less when compared to encryption systems and systems that are more flexible in denial of service attacks which is used for Paillier algorithm which is very difficult because there are not many important numbers.…”

Main problem is when setting up Wireless(W)-Sensor(S)-Network(N) intended for node communication arises for security. Discussed here is a three-tier architecture with two polynomial pools containing wireless routers, key generation center and few access points which are also sensor nodes that can be mobile devices that intend to get better security. The crucial feature of three tier architecture authentication, where communication between WN to access(A) point(P) is established from AP to the sensor node, resulted by pair(P)wise(W) key(K) pre-distribution (PD) methodology and the nodes are authenticated utilizing polynomial keys and Paillier cryptosystem algorithm. Presently, the WN attacks the duplication, such as seeing the nodes in the network. In the event that a nasty node is found and if you want to send packets within the network, you need to store many of keys from both pools for validation. But because there are no sufficient keys available and therefore can't communicate with other nodes in the network. This paper describes an effective contrivance for accomplishing security between node communications by formulating three-level security architecture.

Wireless sensor networks are a challenging field of research when it comes to security issues. Using low cost sensor nodes with limited resources makes it difficult for cryptographic algorithms to function without impacting energy consumption and latency. In this paper, we focus on key management issues in multi-hop wireless sensor networks. These networks are easy to attack due to the open nature of the wireless medium. Intruders could try to penetrate the network, capture nodes or take control over particular nodes. In this context, it is important to revoke and renew keys that might be learned by malicious nodes. We propose several secure protocols for key revocation and key renewal based on symmetric encryption and elliptic curve cryptography. All protocols are secure, but have different security levels. Each proposed protocol is formally proven and analyzed using Scyther, an automatic verification tool for cryptographic protocols. For efficiency comparison sake, we implemented all protocols on real testbeds using TelosB motes and discussed their performances.
