Hybrid Security Framework for Activity Based Authentication using RSA & Genetic Algorithm

In the current information age, security has achieved a tremendous importance in e-commerce applications involving financial transactions. Non-repudiation, data integrity, data confidentiality and authenticity, have become an integral part of information security. There is a tremendous risk involved in the communication of a plain text over Internet. Cryptography offers a solution for this type of risk which is referred to as a technique of encrypting and decrypting messages in such a way that they cannot be interpreted by anybody with the exception of a sender and an intended recipient. In majority of the e-commerce based applications where security is considered to be of prime importance, a single encryption algorithm is adopted for encrypting a password and the authentication information is stored on a single database server which becomes open to risks against different computer hacks. A novel solution for this problem is to generate an individual’s personal and dynamic activities which will be hard for the attackers to guess. Further, this can be combined with distributed technology where the authentication information is distributed over geographically separated multiple servers. In this paper authors have generated an activity based distributed 3D password incorporating various activities where the authentication information is distributed over geographically separated multiple authentication servers. The key pair is generated using RSA algorithm which is encrypted using single-point cross over and mutation of bits at the extreme position. This further adds another level of security and renders the key unbreakable by an unintended user. The configuration information pertaining to the distributed environment is stored in XML file which is parsed using Microsoft's XML Parser and the activity related information is stored in different servers which is encrypted using RSA algorithm. The technique employed combines RSA algorithm with Genetic Algorithm to offer a robust hybrid security framework in a distributed environment which is difficult to guess for an unintended user

A case study to evaluate Jalaukavacharana in the management of Siraja Granthi with special reference to Varicocele

Varicocele is state of varicosity of testicular veins. It is the more frequent and more discomforting condition seen in mostly in teens or in early adult life of males. Occurs in approximately 15-20% of all healthy fertile males and 40% of infertile males. Varicocele can have destructive effects on mobility, concentration and morphology of sperm and can reduce its DNA integrity and other functions. The treatment protocol in varicocele mainly includes laparoscopic ligation of the testicular veins and embolism of testicular vein under radiological control. The major drawback is surgical intervention. It is done only in advanced stage or when there is severe pain or remarkable oligospermia. There are chances of recurrence. There is no direct reference of varicocele as a separate disease in the classics. But Siraja Garnthi is quoted in all Brihatrayees which has similar etiopathogenesis and clinical presentations. The line of treatment mentioned is Siravyadha. Even Purvarupa of Vruddi mentioned by Acharya Sushruta in Vruddinidhna in Nidanastana, can be considered as varicocele. By considering the site and presentation, varicocele can be co-related with Siraja Garnthi of Vrushana Kosha and the treatment protocol to be followed is Siravyadha. Since the pampiniform plexus and testicular veins are of smaller diameter, Jalakavacharana can be considered. Hence, Jalaukavacharana is carried out to see the effectiveness in Varicocele

Design and Development of Deterministic Finite Automata Parser for Querying Hardware and Software Configuration Information of Local Area Network

A typical Local Area Network (LAN) of an educational institution hosts different hardware devices and contains numerous softwares installed, serving the needs of persons from low technical expertise to high technical standards. Further as the academic curriculum is upgraded most of the existing softwares become obsolete and new softwares are installed or existing softwares are upgraded to new version to cater the needs which is a continuous process. To address such issues, a quick and reliable snapshot of the network configuration is desirable at any point of time. On many occasions the softwares with limited usage are installed only on few machines of a LAN. Thus, it proves to be a time consuming task to search the whole network for a single rarely used software. To tackle such issues the authors in the current paper have provided a first hand tool for automating the process of discovering LAN configuration, storing it persistently and querying the stored information in human language. The entire process is automated without any human intervention. The information pertaining to the hardware and software configuration is stored in a persistent Relational DataBase Management System (RDBMS) which can be manipulated by the tool automatically as the new hardware is connected to a LAN or a software configuration changes. The end user instead of querying the database directly will use the natural language, termed as Hardware Query Language (HQL) and Software Query Language (SOQL) designed by the authors, which is interfaced with RDBMS using DFA parser implemented by the authors. To implement HQL/SOQL, a finite set of symbols, words and language rules are defined which together constitute HQL/SOQL grammar. In this paper we present a deterministic finite automata (DFA) parser developed by us for parsing HQL/SOQL tokens. The state table and state diagrams are developed for different tokens of HQL/SOQL identified by us. State information is stored in a persistent database management system as a measure towards improving efficiency and extensibility. Currently, HQL/SOQL consists of only few commands and more commands will be added to HQL/SOQL command set in near future. The reports generated are exported to MS Word using Microsoft Word 12.0 object library

Multi Objective Criteria for Selection of Manufacturing Method using NLP Parser

Installing a manufacturing method might be very expensive and time consuming project. Organization should examine and decide on how best to make this decision of selecting appropriate process meeting their requirements. In order to improve the manufacturing cycle more than 110 manufacturing processes have been proposed. The objectives aimed at and the functions focused on by these processes vary. The process should be flexible enough to accommodate reasonable changes in design. This poses a great challenge to a manager in selection of effective and economical manufacturing process. Different organizations have different objectives and based on their specific requirement they deploy suitable process conforming to their objective. Today’s business scenario is highly competitive, complex and dynamic in nature which demands strategic planning meeting the challenges of changing time. In this paper we have made an attempt to enable the end user a quick selection of appropriate manufacturing method based on multiple objectives. The information pertaining to the method selection is stored in a persistent Relational DataBase Management System (RDBMS) which can be manipulated by the end user as the organizational objectives and the market needs change. The end user instead of querying the database directly will use the natural language, termed as Manufacturing Query Language (MQL) designed by us, which is interfaced with RDBMS using prolog. To implement MQL, we have defined a finite set of symbols, words and language rules, MQL grammar. The parse tree is constructed based on the grammar specified. The NLP query is parsed using NLP parser designed by us and the queries which are successfully parsed are evaluated by mapping them to the corresponding prolog query using Java interface to Prolog (JPL). Prolog rules are stored in three different prolog knowledge bases, mqlgrammar.pl, rules.pl, and methodrules.pl. NLP offers most flexible way to implement grammar which can be readily extended with least efforts and as such offers an efficient way of implementing rules in dynamically changing scenarios. Our current work focuses on a multiple objectives. In real situations multi objective and multi function criteria is required for the proper selection of the manufacturing method. Our future work involves modification of the tool and parser to take account of multiple objectives and function

Cascaded Fuzzy Inference System for Overall Equipment Effectiveness of a Manufacturing Process

Overall equipment effectiveness (OEE) is one of the widely accepted performance evaluation methods most commonly employed for measuring the efficiency of a manufacturing process in a manufacturing industry. It plays a most prominent role in improving the efficiency of a manufacturing process which in turn ensures quality, consistency and productivity. The OEE parameters, availability, performance and quality are not single parameters. But these parameters in turn depend on several other parameters which introduce a cascaded effect in OEE computation. The variation in the value of lowest level parameters propagate to the higher levels making the OEE computation a complex process. To cater such situations, in this paper authors propose cascaded fuzzy inference system for measurement of Overall Equipment Effectiveness. In the simplified model proposed by the authors, only few prominent parameters up to two levels are considered. The model can be easily extended to incorporate more parameters and more levels to render it more realistic

Implementation of Excel Parser for Web Integration of Digital Evaluation System of CSIBER

Digitization and advancements in web technology have facilitated quick access to accurate data irrespective of its location and time zone. Time span becomes crucial in such cases since the data soon becomes stale. Further, web hosts data in variety of formats and sizes. Integrity, authenticity and confidentiality play a key role in data access. The main motto of web data accessibility is that data should be made available only to the person who is authorized to access it. CSIBER has recently installed Digital Evaluation System (DES) for automating the routine tasks of examination department. However, currently the software lacks in web interface. To address this issue, in the current paper, the authors have designed and developed an Excel parser in PHP which acts as an interface between DES and CSIBER’s official website by enabling examinees a quick access to online mark statement. The parser is flexible enough to take care of minor differences in structures of Excel spreadsheets. The deployment folder structure is presented and different cases are explored

Thymosin Beta 4 Prevents Oxidative Stress by Targeting Antioxidant and Anti-Apoptotic Genes in Cardiac Fibroblasts

Thymosin beta-4 (Tβ4) is a ubiquitous protein with diverse functions relating to cell proliferation and differentiation that promotes wound healing and modulates inflammatory responses. The effecter molecules targeted by Tβ4 for cardiac protection remains unknown. The purpose of this study is to determine the molecules targeted by Tβ4 that mediate cardio-protection under oxidative stress.Rat neonatal fibroblasts cells were exposed to hydrogen peroxide (H(2)O(2)) in presence and absence of Tβ4 and expression of antioxidant, apoptotic and pro-fibrotic genes was evaluated by quantitative real-time PCR and western blotting. Reactive oxygen species (ROS) levels were estimated by DCF-DA using fluorescent microscopy and fluorimetry. Selected antioxidant and antiapoptotic genes were silenced by siRNA transfections in cardiac fibroblasts and the effect of Tβ4 on H(2)O(2)-induced profibrotic events was evaluated.Pre-treatment with Tβ4 resulted in reduction of the intracellular ROS levels induced by H(2)O(2) in the cardiac fibroblasts. This was associated with an increased expression of antioxidant enzymes Cu/Zn superoxide dismutase (SOD) and catalase and reduction of Bax/Bcl(2) ratio. Tβ4 treatment reduced the expression of pro-fibrotic genes [connective tissue growth factor (CTGF), collagen type-1 (Col-I) and collagen type-3 (Col-III)] in the cardiac fibroblasts. Silencing of Cu/Zn-SOD and catalase gene triggered apoptotic cell death in the cardiac fibroblasts, which was prevented by treatment with Tβ4.This is the first report that exhibits the targeted molecules modulated by Tβ4 under oxidative stress utilizing the cardiac fibroblasts. Tβ4 treatment prevented the profibrotic gene expression in the in vitro settings. Our findings indicate that Tβ4 selectively targets and upregulates catalase, Cu/Zn-SOD and Bcl(2), thereby, preventing H(2)O(2)-induced profibrotic changes in the myocardium. Further studies are warranted to elucidate the signaling pathways involved in the cardio-protection afforded by Tβ4

Micropropagation and conservation of selected endangered anticancer medicinal plants from the Western Ghats of India

Globally, cancer is a constant battle which severely affects the human population. The major limitations of the anticancer drugs are the deleterious side effects on the quality of life. Plants play a vital role in curing many diseases with minimal or no side effects. Phytocompounds derived from various medicinal plants serve as the best source of drugs to treat cancer. The global demand for phytomedicines is mostly reached by the medicinal herbs from the tropical nations of the world even though many plant species are threatened with extinction. India is one of the mega diverse countries of the world due to its ecological habitats, latitudinal variation, and diverse climatic range. Western Ghats of India is one of the most important depositories of endemic herbs. It is found along the stretch of south western part of India and constitutes rain forest with more than 4000 diverse medicinal plant species. In recent times, many of these therapeutically valued herbs have become endangered and are being included under the red-listed plant category in this region. Due to a sharp rise in the demand for plant-based products, this rich collection is diminishing at an alarming rate that eventually triggered dangerous to biodiversity. Thus, conservation of the endangered medicinal plants has become a matter of importance. The conservation by using only in situ approaches may not be sufficient enough to safeguard such a huge bio-resource of endangered medicinal plants. Hence, the use of biotechnological methods would be vital to complement the ex vitro protection programs and help to reestablish endangered plant species. In this backdrop, the key tools of biotechnology that could assist plant conservation were developed in terms of in vitro regeneration, seed banking, DNA storage, pollen storage, germplasm storage, gene bank (field gene banking), tissue bank, and cryopreservation. In this chapter, an attempt has been made to critically review major endangered medicinal plants that possess anticancer compounds and their conservation aspects by integrating various biotechnological tool
