In structured P2P systems, message deliverance can be done by identifying the peer IDs of the individual systems. The initiator has to decide the destination and can route the message through one or more hops. The message passes from one hop to another correctly by identifying the IP address and finally reaches the destination. In this paper we propose an efficient routing strategy to control the routing path and to identify the malicious nodes. We also eliminate the drawbacks of encryption by introducing steganography in message deliverance. This paper proposes a new steganographic encoding scheme which separates the colour channels of the windows bitmap images and then hides messages randomly in the LSB of one colour component of a chosen pixel where the colour components of the other two are found to be equal to the key selected. In addition to this we apply DCT based Steganography which embeds the text message in least significant bits of the Discrete Cosine (DC) coefficient of digital picture. When information is hidden inside video, the program hiding the information usually performs the DCT. DCT works by slightly changing each of the images in the video, only to the extent that is not noticeable by the human eye. An implementation of both these methods and their performance analysis has been done in this paper.Keywords

In this paper, an encryption technique is proposed based on the general idea that offers efficiency in uploading and downloading a file or data in an encrypted form between peers. The proposed method, introduces a theoretical come practical model that forecasts the act of the system and computes the values of the practical parameters that achieve a desired performance. The proposed method provides very strong security for cooperation and also improves the presentation of P2P networks considerably. In particular, theoretical and realistic models show that it reduces the query response time and file upload and download delays by organizing the magnitude, and doubles the system’s throughput.Keywords

Steganography is a relatively new field of study in Information Technology which deals with information hiding. Steganography or Stego literally means “covered writing”. Steganography is the art and science of communicating in a way which hides the existence of the communication. In divergence to Cryptography, where the enemy is allowed to detect, intercept and modify messages without being able to violate certain security premises guaranteed by a cryptosystem, the goal of Steganography is to camouflage messages in a way that does not allow any enemy to even detect the presence of secret messages. Steganographic research is primarily driven by the lack of strength in the cryptographic systems and the desire to have complete secrecy in an open-systems environment. This paper deals with a brief history of Steganography, various concepts and techniques of Steganography that is used for secure transmission of secret messages or images.

This paper gives an impression of sensor network and its technology and fields of application of sensor networks. It reflects in aspect selected fields of application that have high probability. However studies clearly guess an overall strong positive effect in smart buildings, smart industrial applications as well as precision agriculture and agricultural, consequences for the arena of smart conveyance are diversified due to recoil effects [1]. As significance, demand for transference and thus the consumption of properties both increase which can lead to an overall negative effect.

Human–Computer Interaction (commonly referred to as HCI) researches the design and use of computer technology, focused on the interfaces between people (users) and computers. Researchers in the field of HCI both observe the ways in which humans interact with computers and design technologies that let humans interact with computers in novel ways.
The term was popularized by Stuart K. Card, Allen Newell, and Thomas P. Moran in their seminal 1983 book, The Psychology of Human-Computer Interaction, although the authors first used the term in 1980and the first known use was in 1975.The term connotes that, unlike other tools with only limited uses (such as a hammer, useful for driving nails but not much else), a computer has many uses and this takes place as an open-ended dialog between the user and the computer. The notion of dialog likens human-computer interaction to human-to-human interaction, an analogy which is crucial to theoretical considerations in the field.

Wireless Sensor Network (WSN) is a collection of low energy sensor nodes deployed in hostile complex environments. Their functionality gathers requisite data from the environment and transmits it to the base station for further processing. To enhance the performance of WSN, sensor nodes with different energy levels, capabilities and functionalities are deployed, leading to Heterogeneous WSN (HWSN). The initial energy, energy consumption rate, and residual energy differ for each node in a heterogeneous WSN. Many algorithms were proposed to accomplish an energy-efficient steady HWSN, but the performance level is not satisfactory. This paper presents a novel integrated approach, Energy-Aware Optimal Clustering & Securing Routing (EAOCSR). The algorithm amalgamated three techniques optimal clustering, reliable routing and secured transmission, considering energy retention and network lifetime as the vital parameters. Unequal clustering scheme, trust-based reliable and secure routing forms the core of EAOCSR. The performance of EAOCSR is analyzed using MATLAB simulations. It reveals that the proposed routing protocol EAOCSR has superior performance to existing protocols regarding energy utilization, throughput, network lifetime, stability and security.Keywords
