Modelling client puzzles and denial-of-service resistant protocols
No full textDenial-of-service (DoS) attacks are a growing concern to networked services like the Internet.\ud
\ud
In recent years, major Internet e-commerce and government sites have been disabled due to various DoS attacks. A common form of DoS attack is a resource depletion attack, in which an attacker tries to overload the server's resources, such as memory or computational power, rendering the server unable to service honest clients. A promising way to deal with this problem is for a defending server to identify and segregate malicious traffic as earlier as possible. Client puzzles, also known as proofs of work, have been shown to be a promising tool to thwart DoS attacks in network protocols, particularly in authentication protocols. In this thesis, we design efficient client puzzles and propose a stronger security model to analyse client puzzles. We revisit a few key establishment protocols to analyse their DoS resilient properties and strengthen them using existing and novel techniques.\ud

Our contributions in the thesis are manifold. We propose an efficient client puzzle that enjoys its security in the standard model under new computational assumptions. Assuming the presence of powerful DoS attackers, we find a weakness in the most recent security model proposed to analyse client puzzles and this study leads us to introduce a better security model for analysing client puzzles. We demonstrate the utility of our new security definitions by including two hash based stronger client puzzles. We also show that using stronger client puzzles any protocol can be converted into a provably secure DoS resilient key exchange protocol.\ud

In other contributions, we analyse DoS resilient properties of network protocols such as Just Fast Keying (JFK) and Transport Layer Security (TLS). In the JFK protocol, we identify a new DoS attack by applying Meadows' cost based framework to analyse DoS resilient properties. We also prove that the original security claim of JFK does not hold. Then we combine an existing technique to reduce the server cost and prove that the new variant of JFK achieves perfect forward secrecy (the property not achieved by original JFK protocol) and secure under the original security assumptions of JFK. Finally, we introduce a novel cost shifting technique which reduces the computation cost of the server significantly and employ the technique in the most important network protocol, TLS, to analyse the security of the resultant protocol. We also observe that the cost shifting technique can be incorporated in any Diffine{Hellman based key exchange protocol to reduce the Diffie{Hellman exponential cost of a party by one multiplication and one addition

Gandhi\u27s Other Daughter: Sarala Devi and Lakshmi Ashram
Get PDFIn 1946, Sarala Devi, formerly Catherine Mary Heileman of London, founded a Gandhian training center for women and girls in Kumaon, in what was then the Himalayan region of the United Provinces, India. She and her students challenged conventions regarding gender, sexuality, and appropriate roles for colonial women. This essay analyzes Sarala Devi’s translocal work and shifting subjectivity in the context of her transnational position as she negotiated colonial, modernist, feminist, Gandhian, and village discourses in her mission to “uplift” women. It identifies and analyzes the varied historical contexts, ideologies, and discourses that created the possibility for Sarala Devi’s life and work in the Kumaon Himalaya

How Jang Bahadur established Rana rule in Nepal
No full textThe Kot Massacre of 1846 gave sufficient power to Jang Bahadur to establish his dictatorial rule in Nepal. The butchery began after the murder of Gagan Singh, the power behind the throne on the 14th of September. Almost all the spirited nobles and the highest officers were either killed or exiled. King Rajendra Bikram Shah was on the throne. He was intimidated. He, against his conscience, had to confirm Jang Bahadur's appointment as 'Mukhtyar' and Commander-in-Chief made in his name by Queen Regent Rajya Lakshmi Devi, on whom he conferred all his power and who was the real author of that..
Rigorous, transparent, and eye-catching: Exploring the universalistic parameters of impactful theory building in management
Get PDFIn the management discipline, scholarly impact is most commonly measured using a researcher perspective, by counting the number of times a particular article is mentioned in the references section of other articles (Aguinis, Shapiro, Antonacopoulou, and Cummings, 2014). This approach conceptualizes scholarly impact using a measurable indicator, the citation count an article receives. Several studies have been conducted to examine what drives scholarly impact in the field of management. The originality of the idea, rigor of the study, and clarity of writing have been identified as the most significant universalistic parameters of scholarly impact (Judge, Colbert, Cable, and Rynes, 2007). This dissertation sets out to do a detailed examination of these parameters. The six articles included in the thesis do so in two ways: either by offering recommendations for improving these universalistic parameters of scholarly impact or by further exploring the relationship between the universalistic parameters and scholarly impact. Our first empirical article, here relayed in Chapter II, focuses on case studies, and analyzes the methodological rigor of all case studies published during the period 1996-2006. We point out different types of replication logic, and illustrate how their individual research actions have differential effects on the internal and external validity (in that order of priority) of the emerging theory. Chapter III follows up on the previous chapter, extending the investigation to quantitative as well as qualitative research, and offers replication logic as a tool for analyzing deviant cases identified during the course of a qualitative or quantitative study. We call this technique the ‘Deviant Case Method’ (‘DCM’). Through this study, we explain the theoretical consequentiality (Aguinis et al., 2013; Cortina, 2002) of analyzing three different kinds of outliers (construct, model fit, and prediction outliers/ deviant cases) and offer DCM for analyzing prediction outliers/deviant cases. In Chapter IV, we extend this method to have a look at medium-N studies. Here we focus on inconsistent or deviant cases which turn up during a fuzzy set Qualitative Comparative Analysis (fsQCA). We offer a method called ‘Comparative Outlier Analysis’ (‘COA’) which combines DCM and Mill’s canons (1875) to examine these multitude of inconsistent cases. We explicate this using exemplars from fields like politics, marketing, and education. Unlike in other disciplines or methods, it is far from clear what the label ‘transparent research procedures’ constitutes in management field studies, with adverse effects during write-up, revision, and even after publication. To rectify this, in Chapter V, we review field studies across seven major management journals (1997- 2006) in order to develop a transparency index, and link it to article impact. Chapter VI is a sequel to the previous chapter. We propose a new method for assessing the methodological rigor of grounded theory procedures ex-post using an audit trail perspective. While existing research on the methodological sophistication of grounded theory was typically done from the perspective of the author or producer of the research, our perspective is customer-centric, both in terms of the end-customer (i.e. the reader or other author), as well as the intermediate customer (i.e. reviewers and editors). The last empirical article in the thesis, Chapter VII, focuses on yet another parameter influencing impact: the style of academic writing. Specifically, we focus on the attributes of article titles and their subsequent influence on the citation count. At this early stage of theory development on article titles, we do this in the specific application context of management science. We conclude with Chapter VIII where we sum up the findings and implications of all preceding studies and put forth suggestions for future research
