Carrier data security using public key steganography in ZigBee

The present time has witnessed a tremendous increase in communications over wireless personal area networks. These communications even include credentials or other sensitive information that in any case need to be protected and not to be read by any third party. So the security of such communications has become a concern and should be emphasized accordingly. A secure communication needs to be communicated in a way thats not susceptible to any sort of eavesdropping or interception. The secure communication defends against the unofficial and the unauthorized interceptors from accessing the communications but still delivering the desired content to the intended communicating parties. Security breaches or the interceptors cannot be totally blocked but such procedures should be taken in account that even if an attack or any sort of an intrusion occurs, the parties involved in the communication must be intimated that there has been some sort of an unwanted interference in the communication taking place. This paper presents a proposition for securing the carrier data by means of Public Key Steganography in the wireless personal area network protocol ZigBee. The proposition doles out with dispensing a secret message to the communicating parties in case of an attack or any attempt compromising the security of data.

A heuristic light weight security algorithm for resource constrained DTN routing

Delay Tolerant Network is a buzz word in Mobile Adhoc Network. Research in this direction started with the approach for interplanetary communication. Delay Tolerant Network (in short) DTN is an evolving research area. A way to store, carry and forward messages over the underlying existing infrastructure. The intermittent connectivity and limited resources of a DTN node make the routing difficult to implement in real world application. It is a constant endeavor of any network community to look for security and privacy inclusions in routing protocols. This paper proposes a Light Weight Security algorithm that forwards messages only to the trusted nodes, thus prevents the malicious or selfish nodes from affecting the entire DTN communication. In this paper, the trust value is computed based on their one to one association of mobile nodes in a DTN. Researchers have contributed by proposing a novel solution for detecting hostile mobile nodes. The computed trust value is further used to prevent malicious nodes to compromise the network. The proposed algorithm is simulated and its performance is analyzed with existing based on the performance metrics like overhead ratio, relayed, removed, delivery ratio and hop count. DTN is still evolving and to the best of our knowledge; the proposed work is first of its kind.

A neural network model for electric submersible pump surveillance

The purpose of the study is to make an assessment of the capability of Artificial Neural Network in surveillance of Electric Submersible Pumps, used for lifting oil from mature wells when the natural pressure inside the well is not enough to support the oil flow up to the surface. Electric Submersible Pumps are one of the various processes used to artificially lift oil out of wells when there is insufficient reservoir pressure to keep the well producing. In this paper we will be proposing an Artificial Neural Network model to predict common ESP failures before they occur by identifying the conditions and parameters which may lead to ESP failures. In our approach we will be using the real-time data collected over a period of operation of Electric Submersible Pumps run life containing the information from surface and downhole data which led to ESP failures or trends which may lead to ESP failures. The selected data values from both surface and downhole data values will act as input to the ANN and output of the ANN would be if the input conditions may lead to ESP failure or not. The neural network will be trained to classify the trends or conditions which may lead to ESP failures.

Security in ZigBee Using Steganography for IoT Communications

ZigBee is an IEEE 802.15.4-sourced arrangement for a suite of high-level communication protocols employed to generate personal area networks. ZigBee is a less price, low-complex and low power consumption wireless personal area network (WPAN) norm that targets at the extensive developments of instruments and devices with prolonged battery life that are employed in wireless controls or applications that are used for monitoring purposes. It has an extensive utilization in industries and operations that are conducted physically. Hence, ZigBee is mostly correlated with IoT and M2M. Therefore, security in these WPANs becomes a major interest and has gained a good amount of notice currently. The security methods used in these networks over a period of time usually include practices that are cryptographic in nature. Then again these practices recommended till date can have good scopes of improvements, as a result, to turn up with additional assured and protected data communication. The chapter proposes a technique to enhance security in ZigBee using steganography over the secret data being communicated between communicating parties. However in cryptographic practices, the message even if it stands strongly resilient, can stimulate doubts and, therefore, could be adequate enough for a third party, spying the systems that something that are of significant use have been exposed. Hence, to keep the security features consistent in these networks this chapter proposes a technique to protect data by means of Steganography over the data to be communicated, this allows two communicating parties to transmit covert communication through a shared route in a way with the purpose, no adversary can even discover as in the covert communication is being transferred. Hence, making use of cryptographic practices helps protecting the insides of the messages only, on the other hand using steganographic practices can help in protecting the message contents and even the fact that a covert message has been transferred. The exclusive plan is to come up with a practice that is Steganographic in nature and ultimately has a resistance to any sort of steganalysis.

Performance Evaluation and Analysis of Advanced Symmetric Key Cryptographic Algorithms for Cloud Computing Security

Cloud computing environment is adopted by a large number of organizations, so the rapid transition toward the cloud has fueled concerns on security perspective. Encryption algorithms play the main role in solving such kind of problems in the cloud computing environment. The problem with these encryption algorithms is that they consume a substantial amount of CPU time, memory, and other resources. This paper provides the performance comparison of seven popular symmetric algorithms: AES, DES, 3DES, Blowfish, RC4, IDEA, and TEA. This comparison is done on the basis of encryption time, decryption time, memory usage, flexibility, security, and scalability. The results achieved can be used in cloud-based application and services for the efficient working of cloud computing environment.

Preservation of QoS and Energy Consumption-Based Performance Metrics Routing Protocols in Wireless Sensor Networks

The selection of routing protocols is playing a major role in the device and proper utilization of wireless sensor networks (WSNs) that can help to provide better interconnection networks. On preserving the role of key performance, metric related to routing protocols is also an important and challenging task in the WSNs. Therefore, the sensor nodes life can be improved in efficient manner by using routing protocols that preserve the energy consumption and quality of service (QoS). Three different kinds of categories are used in the design of routing protocols which are data centric, hierarchical, and location-based approaches. Energy consumption can be improved by reducing the effect of redundancy level and transferring the passive motes sleep mode. The data transmission time also impacts on the energy conservation and QoS in WSNs. The surveillance and monitoring-related applications are the demanding research field in the WSNs that has to resolve the issue QoS routing in the manner of reliable data delivery. Energy consumption and QoS constraints are two complementary factors in the routing protocol, but the time delay factor can be involved in such a manner to satisfy both the performance metrics in routing protocol in WSNs.
