The important functionality of cloud is data storage. In this paper, the authors are going to discuss about how to flexibly, efficiently and securely share the data with another client in cloud storage. New public-key cryptosystems is described here that produces constant-size cipher texts that has efficient delegation of decryption rights for any set of ...

Data residing in small chips and hard disks are so much huge that they cannot be easily analyzed manually. So to access useful and knowledgeable information, one has to go beyond human’s reach and rely on a technique of the computer science, that is, data mining which has been in a research area since a ...

Recently the implementations of wireless sensor networks have developed immensely. There is one device which is used in Wireless Sensor Networks (WSNs) to increase the lifetime of the network and give very effective functioning process that is clustering. It is the process in which the whole section or part is divided into small parts which ...

Today website security is the most important feature of securing an organization and should be given higher priority. Day-by-day hackers are mainly targeting on informative websites and web-based applications like forms, sensitive area like login pages, shopping carts, dynamic pages etc. Insecure web applications causes uploading backdoors on the server which allows access to databases, ...

Along with the rapid growth of Wi-Fi-enabled smartphone devices, the need for efficient content sharing techniques for smartphones in Wi-Fi environment has increased. There are many methods recently presented by various researchers for efficient content sharing in Smartphones. However existing methods are suffered from the various limitations. Hence, this area of research is still thought ...

Wireless sensor network extremely popular for monitoring the secluded or unfriendly environments. The duration of the network is the major problem in wireless sensor network. The duration of the wireless sensor is the time in which it covers all the targets. This problem can be solved by observing the less number of the nodule lively ...

Security is one of the major concerns of all the users irrespective of the domain in which they work. There are various ways by which one can ensure the security for the data which is present in different files in the computer. Encryption-decryption is one of those techniques which are quite popular. But, the complexity ...

Wireless Sensor Network (WSN) is a collection of nodes which are deployed in an environment where the data is needed to be sensed to monitor any changes in surrounding. Each node is equipped with memory, battery, transceivers. The nodes are placed in such an environment where monitoring by human is difficult to schedule or managed ...

Due to the rapid growth of internet broadband access and proliferation of modern mobile devices, various types of multimedia (e.g. text, images, audios and videos) have become ubiquitously available anytime. The authors argue that evaluating the user experience of are commander requires a broader set of measures than have been commonly used and suggest additional ...

Mobile Ad-hoc NETwork (MANET) is a network of mobile nodes that can communicate with each other without using any centralized control or fixed infrastructure. In this paper, analysis and performance of AODV, DSR, GRP and OLSR is done for 2Mbps data rate. The authors used OPNET Simulation tool to create a network containing 30 mobile ...
