Anonymous Authentication of Data Stored in Clouds with Decentralized Security Mechanism
Get PDFThe term that flourished in the IT industry is the Cloud Computing. Inspired and Motivated by the tremendous growth and the huge success of cloud, we propose a new decentralized access control scheme for secure data storage in clouds that supports anonymous authentication. In the proposed scheme, the cloud verifies the authenticity of the series without knowing the user’s identity before storing data. Our scheme also has the added feature of access control in which only valid users are able to decrypt the stored information. The scheme prevents replay attacks and supports creation, modification, and reading data stored in the cloud. We also address user revocation. Moreover, our authentication and access control scheme is decentralized and robust, unlike other access control schemes designed for clouds which are centralized. The communication, computation, and storage overheads are comparable to centralized approaches
A Novel Approach to Build Reliable and Efficient Query Services in Cloud with RASP Data Perturbation
Get PDFInspired and motivated by the widespread development and deployment of public cloud computing infrastructures, using clouds to host data query services has become an fascinating solution for the advantages on scalability and cost-saving. However, Data owners show reluctance to share the sensitive and confidential data unless the Data integrity is guaranteed. On the other hand, a secured query service should still provide efficient query processing and significantly reduce the in-house workload to fully realize the benefits of cloud computing. We propose the random space perturbation (RASP) data perturbation method to provide secure and efficient range query and kNN query services for protected data in the cloud. The RASP data perturbation method combines order preserving encryption, dimensionality expansion, random noise injection, and random projection, to provide strong resilience to attacks on the perturbed data and queries. It also preserves multidimensional ranges, which allows existing indexing techniques to be applied to speedup range query processing. The kNN-R algorithm is designed to work with the RASP range query algorithm to process the kNN queries. We have carefully analyzed the attacks on data and queries under a precisely defined threat model and realistic security assumptions. Extensive experiments have been conducted to show the advantages of this approach on efficiency and securit
Carbon Nanotube based approach on FETs using Ternary Comparator
Get PDFA Carbon Nanotube Field Effect Transistor (CNFET) is referred to as a FET that utilizes a single Carbon Nanotube or an array of carbon nanotubes as the channel material instead of bulk silicon in the traditional MOSFET structure. New approach of ternary magnitude comparator based on the CNFET ternary logic gates. These gates are promising alternative to conventional logic design because of its energy efficiency, it can accomplish by the reduced circuit on ternary logic. Ternary comparator implementation is based on prefix based design and combines ternary and binary logic gates for optimized implementation. A novel approach of a comparator has been implemented and simulated using SPICE. A design response indicates that the 1-bit comparator consumes less power say 0.65µW and has a delay of 21ps. The simulation results for comparators with versatile lengths of operands
Structural and Thermal Analysis of Disc Brake With and Without Cross Drilled Rotor
Get PDFThe disc brake is a device for slowing or stopping the rotation of a wheel. A brake disc (or rotor), usually made of cast iron or ceramic composites (including carbon, Kevlar and silica), is connected to the wheel and/or the axle. To stop the wheel, friction material in the form of brake pads (mounted on a device called a brake caliper) is forced mechanically, hydraulically, pneumatically or electromagnetically against both sides of the disc. Friction causes the disc and attached wheel to slow or stop. Brakes convert friction to heat, but if the brakes get too hot, they will cease to work because they cannot dissipate enough heat. This condition of failure is known as brake fade. Disc brakes are exposed to large thermal stresses during routine braking and extraordinary thermal stresses during hard braking. The aim of the project is to model a disc brake used. Coupled field analysis (Structural + Thermal) is done on the disc brake. The materials used are Cast Iron, stainless steel and aluminum alloy. Analysis is also done by changing the design of disc brake. Actual disc brake has no holes, design is changed by giving holes in the disc brake for more heat dissipation. Modeling is done in Pro/Engineer and analysis is done in Ansys
Design and implementation of Traffic Flow based Street Light Control System with effective utilization of solar energy
Get PDFStreet Light Control System which operates automatically is not only easiest but also the intelligent system. This system can be set to operate in automatic mode, which regulates the streetlight according to detection of moving object. The main objective of this project is to save the power from street lighting in rural areas where there will be very less use of street lights after 11pm to morning 5am. So here, in this project we use automatic ON/OFF mechanism of street lighting by detecting the movement of object (vehicle/person). In this project, we use renewable source of energy i.e., solar power for street lighting. Apart from this, we replace normal bulbs in street lighting with LEDs due to which the power consumption in reduced by 3 times. And also, we use IR sensors to detect the movement of object to activate the lighting a few meters before the object is about to reach the lighting area. Here, the IR sensors are deactivated after a timing delay of 30seconds and similarly remaining sensors are activated and deactivated after 30seconds. We also place a battery backup for 2days in order to supply power continuously in the worst cases such as rainy time. We also connect this solar power region to the grid to supply excessive power to the grid to avoid saturation of battery and also vice-versa i.e., to receive power from grid in rainy seasons and winter seasons. So, this is a very effective way of saving a large amount of power

No full textGeo-social applications function on fine-grain, time-stamped location information. For existing services with negligible solitude mechanisms, this data can be used to deduce a user’s detailed activities, or to path and forecast the user’s every day movements. The confront, then, is to intend mechanisms that powerfully guard user privacy with no give up the correctness of the system, or making brawny assumptions about the sanctuary or dependability of the application servers. More particularly, we objective geo-social applications, and presume that servers and any mediators can be conciliation and, therefore, are untrusted. To edge maltreatment, our ambition is to border convenience of location information from global visibility to a user’s communal surround
A Newfangled Authentication Protocol Based On Audio Produced Principles
Get PDFGraphical authentication is more proficient and more securable. An imperative convenience objective for information based authentication frameworks is to bolster client in selecting passwords for higher security in the feeling of being from an extended viable security space. Here we are utilizing x and y directions to pick a photo secret word. Also the photos in x and y directions are changing haphazardly and subsequently it is hard to locate the first picture. In our base paper the methodologies utilized are "Convincing signaled snap focuses"," Cued snap focuses" and "Pass focuses". Primary apparatuses utilized here are pccp, viewport and that is utilized for secret word creation. Viewport methodologies are utilized to significant client picked secret word and secure framework created arbitrary watchword that are hard to recollect. The pccp making a less guessable secret key is the least demanding game-plan. With a specific end goal to dodge "Shoulder surfing" calculation we are going for AES (Advanced encryption standard). In a contemporary mastery, the customary Authentication methodologies like "alphanumeric - usernames and passwords" can't be a versatile secured technique as it make out a critical downsides. It can't be protected and sound from programmers. Graphical passwords are a different option for existing alphanumeric passwords. In Graphical passwords clients click on pictures than sort a long, complex secret key. Exhaustive examination is finished by different analysts proposes that the photo's majority based authentication plans are essentially delicate as client tends to tap on hotspots in the pictures. A hotspot is the picture's territory which is effectively perceived against every single other picture, accordingly making such strategies defenseless. To make greater from the available confirmation, another convention "in light of the sound time stamps" making it hard for the shams to perform mystery. Here is a novel one of a kind answer for graphical validation defining so as To take into account sound time stamps another method for model called "A NEWFANGLED AUTHENTICATION PROTOCOL BASED ON AUDIO PRODUCED PRINCIPLES ". This model calls a sound time stamps and in addition the number of sound timestamps and scramble the secret word with message digest adaptation 5 and making it hard for the gatecrasher to break the watchword there by forcing the more elevated amounts of security to the framework. The gatecrasher can't get the time stamps and additionally check of time stamps and making this strategy more secure, dependable and difficult to figure
