Design of cryptographic algorithms has ever been meant for making messages confidential strong enough for cryptanalysts. This has resulted into different categories of encryption/decryption algorithms while they have their own pros and cons. The cryptanalysts have played roles in observing confidential messages, identifying used algorithms to encrypt messages, and they have been successful in exploiting the weak points, if found any, in the algorithms’ designs. But Hybrid cryptographic algorithms, which bring mixture of randomness in the ciphered text, are ones of some obstacles for them. It is more difficult to break the hybrid ciphered text than that of block or stream cipher text. The current work presents design of a hybrid algorithm that makes uses of content replication removal in input data, block cipher and stream cipher cryptographic algorithms. © 2018, Springer Nature Singapore Pte Ltd.

BRRC: A Hybrid Approach Using Block Cipher and Stream Cipher

As urban living environment is becoming more and more complex; the road condition is becoming worse because of heavy traffic, increase of traffic accidents and high ratio of empty vehicles. It increases the cost of transportation and wastes time of vehicle movement. In highly populated Countries like India, during accidents, people lose their lives due to unavailability of proper medical facilities at the right time. This project senses any accident in the vehicle and intimates pre-programmed numbers like family members of the rider, ambulance, police station and nearest hospital etc. The GSM technology is used to send the position of the vehicle as a SMS to those numbers. And also the position of the vehicle can be obtained. Most of the companies want to keep track of their vehicles, with this equipment we can keep track of the vehicle by periodically sending SMS and the position of the vehicle is sent by the GSM modem as a SMS to the user. In this project an electronic device is installed in a vehicle and helmet to enable the hospital (ambulance-108), police station and relative of the driver to track him if he has been met with an accident and get immediate hospitalization. It is an embedded system which is used for tracking and positioning of any vehicle which is met with an accident by using Global Positioning System (GPS) and Global System for Mobile Communication (GSM). This design will continuously monitor a moving vehicle along with rider wearing the helmet and report the status on demand and will send rescue message when met with an accident. For doing so a Renesas microcontroller is interfaced serially to a GSM Modem and GPS Receiver. A GSM Modem is used to send the position (latitude and longitude) of the rider. The GPS modem will continuously give the data i.e. the latitude and longitude indicating the position of the rider. The same data is sent to the mobile numbers and 108. © 2016 IEEE.

Cloud computing being promising and emerging technology for the next generation of IT applications which provides the storage and supports for outsourcing of data without having the native copy of data or files. Cloud computing service providers require a system which can handle a large number of requests at a time and is needed to be highly available. Major issue faces in cloud computing is Security and data retrieval. In data security an important problem is to prevent illegal modifications and data loss. But, for this it requires either data replication or on-demand computation of a function over the entire contract out data. Generally system keeps multiple copies of the blocks of data on different nodes by replication. Another issue is retrieval of data, whereas in the cloud computing environment it becomes particularly serious because the data is located in different places even in the entire globe. Load on system may increase when there is high demand of a data. In this, the main focus is on the problems of security, replication and availability of data. The proposed system use a fragmentation and sole replication (FASR) concept in the cloud to improve the security and data retrieval time rather than using traditional cryptographic techniques. It fragments the file, place every single fragment in distinct node and perform sole replication that is every fragment is replicated only once, to provide security. Particularly selection of primary node is done through hotbed measure, selection of node and placement of other fragments is done through T-coloring technique, which limits tampering of data. Thereby improve retrieval time for easy accessing of the fragments for reconstruction of original file on user request. In this user can download, update and upload the file again. User can also request for required fragments and can update, upload it to cloud. Another automatic updating technique is proposed which allow uploading of only updated fragment in the cloud node. FASR concept provides security; save time and automatic updating technique reduce the resource utilized. Non-cryptographic nature makes the system even faster. © 2016 IEEE.

Improve the data retrieval time and security through fragmentation and replication in the cloud

Compromising databases of servers of a login system result in successful theft of login credentials. Storage of these credentials as part of the authentication system makes a login system vulnerable for the theft. Various types of malicious activities have led in revealing this pair of information which attack on the stored database. We propose a novel concept for login systems which does not store such credentials in the database. The credentials are generated and verified algorithmically. It is also ensured that the generated credentials are human friendly for uses. © 2016 ACM.

Data mining has been used as a technology in various applications of engineering, sciences and others to analysis data of systems and to solve problems. Its applications further extend towards detecting cyber-attacks. We are presenting our work with simple and less efforts similar to data mining which detects email based phishing attacks. This work digs html contents of emails and web pages referred. Also domains and domain related authority details of these links, script codes associated to web pages are analyzed to conclude for the probability of phishing attacks. © 2015 IEEE.

Copy on write technique to modify a shared memory page has been a novel idea by keeping the original page unchanged and modifying a duplicate copy of it. The modifiable content in a page can range from one byte to a complete page. The process which owns the page to be modified is kept suspended until the whole page is copied down. Page copying is done without caring the size of modifiable content. Process suspension and page content copying take further time. Also minor page fault is raised as further activity. COW technique, in virtual machines, to save redundant physical memory space is resulting today in memory disclosure attacks. Our work BMCOW as bytes modification & COW modifies shared pages in a way such that COW works on only unreferenced bytes of the pages and thus it avoids extra time of modification process. This avoids any known timing based attacks on virtual machines' memory. © 2015 IEEE.

BMCOW: An approach to modify shared page

Generally, user authentication performs through user's Id and password. In this process, user id remains visible and password remains secret. But through shoulder surfing and other attacks, the password can also be traced due to exact password characters are typed or marked by users during login. To counter this vulnerability of tracing password, we propose a novel login method that does not reveal the user-id/password even if keylogging traces the typed keyboard's characters. We also do a security analysis to show that proposed mechanism is able to withstand a number of attacks and also mitigates some of the attacks. We also do a usability survey to show its feasibility among real-time users without compromising any security features. © 2016 ACM.

Three steps secure login: A systematic approach

In this Paper, we have proposed a new captcha based on digits and symbols. It is based on the facts that it is difficult for the machine to interpret symbols and perform the tasks accordingly from two different datasets. We have also pointed out the main anti-recognition and anti-segmentation features from previous works and implemented them on our proposed captcha. We have also presented here the pseudocode of it, have done a security analysis and usability survey to firm our claims regarding it. © 2015 IEEE.
