As a potential technology, the identity-based online/offline encryption scheme is split into two phases (the offline phase and the online phase) which is especially suitable for sensor nodes with limited computation resources in that most of the works can be executed offline. However, a challenging issue is the well-known identity-based online/offline encryption schemes unable to resist continual key leakage attacks of the secret keys. To address the above security challenge, we put forth the first continual leakage-resilient identity-based online/offline encryption scheme which is suitable for ensuring secure communications in wireless sensor networks. More specifically, our formal security proofs analysis indicates that the proposed scheme can guarantee security even if partial information of the secret key is continually leaked due to side-channel attacks or fault injection attacks. Above all, compared to the existing identity-based online/offline encryption schemes, an identity-based online/offline encryption scheme with continual leakage resilient meets wireless sensor networks with strong security.

Identity Based

Fog networking supports the internet of things (IoT) concept, in which most of the devices used by humans on a daily basis will be connected to each other. Security issues in fog architecture are still a major research area as the number of security threats increases every day. Identity-based encryption (IBE) has a wide range of new cryptographic schemes and protocols that are particularly found to be suitable for lightweight architecture such as IoT and wireless sensor networks. This chapter focuses on these schemes and protocols in the background of wireless sensor networks. Also, this chapter analyses identity-based encryption schemes and the various attacks they are prone to.

Symmetric Key Cryptography

It is challenging to secure a wireless sensor network (WSN) because its inexpensive, tiny sensor nodes do not have the necessary processing capability, memory capacity, and battery life to take advantage of the existing security solutions for traditional networks. Existing security solutions for wireless sensor networks are mostly based on symmetric key cryptography with the assumption that sensor nodes are embedded with secret, temporary startup keys before deployment thus avoiding any use of computationally demanding public key algorithms altogether. However, symmetric key cryptography alone cannot satisfactorily provide all security needs for wireless sensor networks. It is still problematic to replenish an operational wireless sensor network with new sensor nodes securely. Current research on public key cryptography for WSNs shows some promising results, particularly in the use of elliptic curve cryptography and identity based encryption for WSNs. Although security is essential for WSNs, it can complicate some crucial operations of a WSN like data aggregation or in-network data processing that can be affected by a particular security protocol. Accordingly, in this chapter, the authors summarize, discuss, and evaluate recent symmetric key based results reported in literature on sensor network security protocols such as for key establishment, random key pre-distribution, data confidentiality, data integrity, and broadcast authentication as well as expose limitations and issues related to those solutions for WSNs. The authors also present significant advancement in public key cryptography for WSNs with promising results from elliptic curve cryptography and identity based encryption as well as their limitations for WSNs. In addition,they also discuss recently identified threats and their corresponding countermeasures in WSNs.

The security of wireless sensor networks is a significant concern and can be achieved by the application of cryptographic algorithms. The symmetric key encryption techniques are widely used cryptographic mechanisms for the security of sensor networks due to its low computational complexity. A symmetric key encryption technique requires a secret key to be shared between both parties for confidential communication. In a wireless sensor network, it is difficult to know which node is going to be in its communication range at the deployment phase. If prior knowledge of sensor location exists, it is an added advantage and helps in the distribution of secret keys among nodes. Even if with the expected location information, distributing the keys properly among the nodes is a challenging task. A proper algorithm must be used so that it gives the adequate utilization of the distributed keys with a minimal number of keys per sensor node. In this paper, we propose a location-dependent key distribution scheme. We use Delaunay Triangulation for the efficient distribution of keys among sensor nodes. The method gives a high probability of secure communication links among nodes with high resilience to the network.

The use of Wireless Sensor Networks (WSN) in the field of military, battlefield, healthcare applications etc has seen a plethora of growth towards variety of sensory devices. Irrespective of different locations, the sensor nodes has to do its task. Hence, the dynamic wireless sensor networks should ensure better quality of sensor nodes that covers wider network area and additional services in relative to static WSNs systems. By doing so, it requires secure data communication among the sensor nodes in wireless environment. Key Management is the recent security concept enabled to provide secure communication between sender and receiver nodes. In this paper, we have proposed efficient key updates systems between the nodes. In any scenario, the nodes may join or leaves the network environment which facilitates to initiate a secret key between intended sender and intended receiver. A certificate less key secrecy system is designed for secure communication in wireless links. By designing so, we have addressed the issues like node authentication, data confidentiality and data integrity. Experimental analyses have shown the effectiveness of proposed system.

Wireless Sensor Networks is an emerging trend and has become gradually popular across wide range. A key distributional protocol is intended to safely provide authentic motes with secret keys system using Elliptic Curve Cryptography functions. The convention is a variation of the Diffie_Hellman convention utilizing Elliptic Curve Cryptography. It’s agreement of a key convention that permits pair of gatherings, both having a elliptic open and closed key, to build up a mutual secret key over an uncertain channel. This shared secret key may be either utilized as key or used to determine another key which would then be able to be utilized to subsequent correspondences utilizing a cipher of symmetric key. The use of advanced encryption standard for the encrypt and decrypt of the data also ensures that security is never flawed. Therefore Elliptic curve cryptograph is a best candidate for providing secure communication between Wireless Sensor Networks.
