Abstract Content-Centric Network (CCN) or Named Data Network (NDN) is a new face or dimension in transfer of data between sender and receiver. It provides Internet architecture for future utilization, provided by empirical research for growing complexities and problems in traditional Internet architecture e.g. internet Protocol (IP) [1],[2] It is developed to focus on content distribution instead of host to host communication. Being content-centric rather than host-centric brings many advantages

Glossary 3DES (Triple DES): An enhancement to the original DES algorithm that uses multiple keys to encrypt plaintext. See also DES. AAA: Shorthand for the system controls authentication, authorization, and accountability. Abstraction: A process of viewing an application from its highest-level functions, which makes lower-level functions abstract. Access control: The ability to permit or deny the use of an object (a passive entity such as a system or file) by a subject (an active entity

Summary Basically there are two hiding techniques and those are Cryptography and Steganography. In cryptography an encryption and decryption keys will be available for encoding and decoding purpose respectively and it is having triple key to provide secured data to the receiver safely. Now in steganography not only encryption and decryption are to be done but there is cover media to provide more security and that is known as chaotic image

A Proposal on: How to Preserve Privacy and User Control in a world of Big web Data Background to the study Over the past few years, the volume of data collected and stored by business and government organizations has exploded. This data are refer to as “big data”, as it is an evolving term that describes any voluminous amount of structured, semi-structured and unstructured data that has the potential to be mined for information. The big data is a by-product of everyday human activities on the

securing communication between parties in presence of potential adversaries. A cryptographic algorithm or cipher is a mathematical function used in a plaintext in the encryption and decryption process. A cryptographic algorithm works in combination with a key (number, word, or phrase) to encrypt the plaintext. The same plaintext also

Literature Review on security of Internet of Things Department of Electronics and Telecommunication Engineering, College of Engineering, Pune, India Abstract The concept of the internet of things is that every physical of object in the real world has a virtual component on the internet that can produce and consume services .Such super connected objects would be of great convivences but they would require novel approaches to ensure security and ethical uses. While internet of things is more than

Cloud Service provider and TPA. Techniques like authentication and encryption are important, our system can provides those things for security issues. Second: in recent research POR protocol in which the verifier stores only a single cryptographic key, POR can only capable of detection of file corruption or loss, and not prevention. Maintaining the storages can be a tough task and second it requires high resource costs for the implementation. This paper, Propose a formal analysis method called full

Data Encryption I. What is Data Encryption? Data encryption describes the transformation of plain text into a different format that is meaningless read by human eye without being decrypted, so called cipher text, in order to prevent any unauthorized party to obtain information from the document. According to the Webster dictionary, “cryptography is the practice and study of data encryption and decryption - encoding

This can be any medium such as cellular or satellite transmission. MANETs can work both as a host and a router. Since, there is no central infrastructure and nodes are free to move, the neighboring nodes help in data transmission that are not in the communication range. This can be achieved by dividing the MANETs into two types of networks i.e. single hop network and multihop network. In a single
