    The present report contains the pre-proceedings of the third international Workshop on Formal Aspects in Security and Trust (FAST2005), held in Newcastle upon Tyne, 18-19 July 2005. FAST is an event affliated with the Formal Methods 2005 Congress (FM05). The third international Workshop on Formal Aspects in Security and Trust (FAST2005) aims at continuing the successful effort of the previous two FAST workshop editions for fostering the cooperation among researchers in the areas of security and trust. The new challenges offered by the so-called ambient intelligence space, as a future paradigm in the information society, demand for a coherent and rigorous framework of concepts, tools and methodologies to provide user\u27s trust&confidence on the underlying communication/interaction infrastructure. It is necessary to address issues relating to both guaranteeing security of the infrastructure and the perception of the infrastructure being secure. In addition, user confidence on what is happening must be enhanced by developing trust models effective but also easily comprehensible and manageable by users

    Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 2012.This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Cataloged from student-submitted PDF version of thesis.Includes bibliographical references (p. 177-194).Privacy and integrity concerns have been mounting in recent years as sensitive data such as medical records, social network records, and corporate and government secrets are increasingly being stored in online systems. The rate of high-profile breaches has illustrated that current techniques are inadequate for protecting sensitive information. Many of these breaches involve databases that handle information for a multitude of individuals, but databases don't provide practical tools to protect those individuals from each other, so that task is relegated to the application. This dissertation describes a system that improves security in a principled way by extending the database system and the application platform to support information flow control. Information flow control has been gaining traction as a practical way to protect information in the contexts of programming languages and operating systems. Recent research advocates the decentralized model for information flow control (DIFC), since it provides the necessary expressiveness to protect data for many individuals with varied security concerns.However, despite the fact that most applications implicated in breaches rely on relational databases, there have been no prior comprehensive attempts to extend DIFC to a database system. This dissertation introduces IFDB, which is a database management system that supports DIFC with minimal overhead. IFDB pioneers the Query by Label model, which provides applications with a simple way to delineate constraints on the confidentiality and integrity of the data they obtain from the database. This dissertation also defines new abstractions for managing information flows in a database and proposes new ways to address covert channels. Finally, the IFDB implementation and case studies with real applications demonstrate that database support for DIFC improves security, is easy for developers to use, and has good performance.by David Andrew Schultz.Ph.D

    Greece between East and West: a survey and an historical interpretation

    Thesis (Ph.D.)—-Boston University.Greece's difficulties are not new nor entirely Greek and they became acute, from time to time, as a result of unusual circumstances. Deep problems underlie the fluctuating currents of Greek history, and the Great Powers have been party to many of Greece's difficulties, while Greece's neighbors have been instruments of Great Power machtpolitik in the Balkans. Greece's tragedy has been fourfold: first, its territory occupies the peninsula which commands an arena of intensepolitical rivalry. Second, since its creation it has been a small and poor nation occupying a strategic geographic position. Third, Greek liberation was made possible by the aid of many Powers that continued to retain their "interest" in Greece. Lastly, Greek nationalism which found fertile soil in the "Great Idea" with the belief that for survival the little kingdom had to strengthen itself economically and politically by absorbing adjacent lands. These lands, however, more often than not, were inhabited predominantly by Greeks who were faced with absorption or annihilation by a reawakening of Slavic Balkan peoples or renascent Ottoman nationalism. This situation led to a fervent and natural desire for enosis by exohellenes and the historical anagke and almost religious passion felt by the Greek Government to effect a union so long sought after and for so long desired. From the outset the Greeks were caught between East and West, for Greece's independence and later the extension of its boundaries could be realized only at the expense of Turkey and the policies of Austro-Hungary and England. For Austria, a continental Power, this meant maintenance of Metternich's "consecrated structure"; for England, an insular Power, it meant maintenance of the integrity of the Ottoman Empire since its dissolution would not only disrupt the equilibrium of Europe but its dismemberment would remove the last substantial political bulwark to Russian expansion. It is not surprising that Castlereagh could set aside his doctrine of noninterference in the Greek issue since, as in the Lowlands, its application would have threatened British interests. At the same time, Greece could expect little from Russia, for concessions from that quarter, notwithstanding the Tsarist ruse of protecting co-religionists would be at the expense of PanSlavism and Tsarist expansion. Furthermore, being non "Catholic," Greece could expect no sympathy from Catholic powers. Finally, her early boundaries, like most boundaries in the Near East, reflected neither a political nor an economic necessity but were drawn to guarantee weakness and rivalry and became an object of power politics. This inherent situation has brought Greece periodic chastisements and unsolicited transgressions by the Great Powers with serious effects on her domestic life as well as her inter-national position. Historically, Austria-Hungary, England, France, and Germany, individually or in collusion, had prevented Russian domination of the Balkans and the Near East; but recent history proved more favorable to the Soviet Union until Soviet designs against Greece and Turkey after World War II forced the United States to take a series of decisive actions best described as the "Truman Doctrine" which caused international Communism to suffer in Greece its first and only major defeat in the post-war period. As a result, Greece found a new protector in the United States, but at the same time fell more securely into the Western orbit. In 1841, Sir Edmund Lyons, the British Minister to Athens, made the prophetic statement, "A Greece truly independent is an absurdity. Greece is Russian or she is English; and since she must not be Russian, it is necessary that she be English." In 1947, the Truman Doctrine reaffirmed this dictum with the modification that since Greece cannot be English, it is necessary that she be "American.

    A Historical Analysis of South Holland School District 151 Desegregation Order: An Examination of Superintendent Decisions Based on Board Actions Grounded in the Context of Prevailing Social, Political, Legal and Educational Conditions for the Period 1967-2010

    This study provided a historical analysis of the 1968 court ordered desegregation of South Holland School District 151. The purpose of this case study was to examine, according to primary source evidence, how the superintendents grounded their decisions within the prevailing social, political, legal and educational conditions of the time. The researcher applied the leadership framework of Sergiovanni\u27s Five Sources of Authority by identifying words and actions of superintendents that support a source of authority. This case study sought to identify how the decisions made, actions taken, and resulting changes created a new context for each succeeding superintendent to operate within. This case study also examined how each superintendent brought awareness to the board of the prevailing social, political, legal, and educational conditions of the time as the rationale for the need to develop policy and/or make decisions. An examination of the board\u27s policies and/or decisions was made to identify what values were represented based on a superintendent\u27s contextual descriptions of the district\u27s needs. This study began with the early history of the Village of South Holland and examined the religious and political influences that guided the transformation to a suburban setting from a rural community. The study followed the development of South Holland School District 151; examined the factors that contributed to the charges of unequal treatment by the African American Phoenix community; and concluded with the process of desegregation and the impact upon the school community

    Originally published in 1963. In 1958 Nikita Khrushchev demanded that the United States, Great Britain, and France withdraw from West Berlin. His demands eventually resulted in the division of Germany's capital city through the building of the Berlin Wall. In The Defense of Berlin, Jean Edward Smith discusses Berlin from the time of arrangements set during the war through 1962, with an emphasis on the effect that the crisis of division had on the city
