In this article, a novel security model for the Hadoop environment has been developed to enhance security credentials of handheld systems. The proposed system deals with enabling Hadoop security in terms of a dataset and a user which is willing to access the content inside the Hadoop system. It...

Following the rapid development of the Internet of Things (IoT) technology worldwide, the integration of the IoT to the cloud, referred to as the Cloud of Things (CoT), has become essential for easy access and management of remote resources. However, security and malicious intrusions must be...

It is widely recognized that the public-key cryptosystems are playing tremendously an important role for providing the security services. In majority of the cryptosystems the crucial arithmetic operation is modular exponentiation. It is composed of a series of modular multiplications. Hence, the...

Information security using data hiding in video provides high embedding capacity and security. Steganography is one of the oldest data protecting methodologies deals with the embedding of data. Video Steganography hides secret information file within a video. Present day communications are...

WSN is a promising approach for variety of different real time applications. Different Routing protocols for WSNs are very effective challenge in present days because of scalability, efficient energy utilization and robustness in large number of wireless sensor networks with consists of more...

Purpose Quantum key distribution (QKD) is a technology, based on the quantum laws of physics, rather than the assumed computational complexity of mathematical problems, to generate and distribute provably secure cipher keys over unsecured channels. The authors are using this concept of QKD for...

This paper addressesthe use of Steganography over the Internet by terrorists. There were ru-mors in the newspapers that Steganography is being used to covert communication between terrorists, without presenting any scientific proof. Niels Provos and Peter Honeyman conducted an extensive Internet...
