Hashing Routing
No full textA recent trend in ad hoc network routing is the reactive on-demand philosophy where routes are established only when required. Mostly work has been concentrated on routing aspect. Most of the protocols in this category are not incorporating proper security features. Security is one of the most important concepts in ad hoc networks. It has been observed that different protocols need different strategies for security. The study here proposes a theory in this article based on Hashing as a tool. This scheme can make most of the on demand protocols secure. The study should help in making protocols more robust against attacks and standardize parameters for security in routing protocols
“Botnet” - Most Serious Network Threat against CyberSecurity Faced by Online Ecosystems and Computing Assets
No full textThe rapid usages of the Internet over the past few years have facilitated an increase in the incidents of online attacks. One of the most vexing cyber-security threats today is the use of very large, coordinated groups of hosts for brute-force attacks, intrusions, and generating unsolicited emails. The denial of service (DoS) attack is one such powerful attack. If the attack is distributed, it leads to a very significant damage to the network. A distributed denial of service (DDoS) attack is launched by a mechanism called Botnet through a network of controlled computers. Vulnerable hosts are turned into so-called zombies which can be controlled from afar. A collection of zombies called bots, when controlled by a single command and control (C2) infrastructure, form what is called a Botnet. Botnet are network threats that generally occur from cyber-attacks, which results in serious threats to our network assets and organization’s properties. Malicious botnets are distributed computing platforms predominantly used for illegal activities such as launching Distributed Denial of Service (DDoS) attacks, sending spam, trojan and phishing emails, illegally distributing pirated media and software, force distribution, stealing information and computing resource, e-business extortion, performing click fraud, and identity theft. In this article we try to provide information on how Botnet facilitate distributed denial of service (DDoS) attacks that hamper the Web server. Botnets compromise a network of machines with programs (usually referred to as a bot, zombie, or drone) and implement under a command and control (C&C) management infrastructur

Distributed Denial-of-Service Attack: A Malicious Hacker Attempt to Prevent Legitimate Users from Accessing Information or Services
No full textDenial of Service attack, is the one in which an attacker attempts to prevent legitimate users from accessing information or services. It is a malicious attempt by a single person or a group of people to cause the victim, site, or node to deny service to its customers. Flooding a network with information is the common form of DoS attack. When you type a URL for a particular website into your browser, you are sending a request to that site's computer server to view the page. The server can only process a certain number of requests at once, so if an attacker overloads the server with requests, it can't process your request. This is a "denial of service". The attack becomes more successful with an abundance of attack packets i.e. the attack takes place simultaneously from multiple points. This type of attack is called a Distributed DoS, or DDoS attack

Revolutionize Efficiency of Solar PV Modules by using Nanotechnology
No full textNanoscale technology may be the mantra that will unlock the secret to major advancements that would fulfill the need for clean and renewable sources of energy. Find out more about this path-breaking discovery. Clean power generation from renewable energy is seen as the solution to the climate impacts of the energy sector. However, there are barriers yet to be overcome to scale up energy production through renewable. The conversion efficiency of a solar cell is the percentage of the solar energy shining on a PV device that is converted into electrical energy. Improving conversion efficiency is a key goal of much research and help to make PV technologies cost competitive with more traditional source of energy. A novel structure of photovoltaic cell design is demonstrated theoretically in this study which can improve conversion efficiency drastically and can reduce size of module too. This structure of cell can capture sunlight from all direction except bottom surface. The architecture is different from that of conventional PV cells which is like plates in which top surface receives sunlight. This new three dimensional cells resembles a tiny tower and several such towers can be staked like a high rise building. Fabrication of the cells begins with a silicon wafer, which can also serve as the solar cell’s bottom junction. The advantages of nanotubes over metallic grids are dimension reduction thus reduced loss owing to shading, nanotubes provide one dimensional conduction, and nanotubes can be impregnated subsurface eliminating shading loss completely and also capturing charges which are unable to reach to surface The main challenges now for the application of nanomaterials in the energy sector are the improvement of efficiency, reliability, safety and lifetime, as well as the reduction of costs. To date, universities, research institutes, and even governments are paying attention to the synergy that could be established between nanotechnology and renewable energy. In Singapore, the Institute for Bioengineering and Nanotechnology was created to work closely on the field.Recently, the institute has developed a more efficient and longer lasting fuel cell through a compound of gold, copper and platinum nanoparticles. The researchers found out that replacing the innermost part of the catalyst of the fuel cell with gold and copper alloy, while leaving just the outer layer in platinum, will deliver five times higher activity. Platinum nanoparticles are often used as catalyst in commercially available fuel cells, since platinum is the only metal that is resistant to extreme acidic condition inside such a cell. The prevalent use of fuel cells has been deterred by the high cost of platinum and its low stability. The new advanced fuel cell material could help overcome these barriers, providing a less expensive material and much greater stability. In 2011, the US President Barack Obama launched the Advanced Manufacturing Partnership, a national effort by the industry, universities, and the federal government that provides more than $500 million in investments in emerging technologies such as information technology, biotechnology, and nanotechnology. To conclude, nanoscale technology looks promising as a major contributor to advancements needed to fulfill the potential of emerging sources of clean, renewable energy. Progress in the comparatively new area of nanoelectronics in particular could be the basis for new manufacturing processes and devices to make renewable energy systems and technologies more efficient and cost-effective
