Cryptography
56 Protecting Information With Cryptography Chapter by Peter Reiher (UCLA) 56.1 Introduction In previous chapters, we’ve discussed clarifying your security goals, determining your security policies, using authentication mechanisms to identify principals, and using access control mechanisms to enforce poli- cies concerning which principals can access which computer resources in which ways. While we identified a number of shortcomings and prob- lems inherent in all of these elements of securing your system, if we re- gard those topics as covered, what’s left for the operating system to worry about, from a security perspective? Why isn’t that everything? There are a number of reasons why we need more. Of particular im- portance: not everything is controlled by the operating system. But per- haps you respond, you told me the operating system is all-powerful! Not really. It has substantial control over a limited domain – the hardware on which it runs, using the interfaces of which it is given control. It has no real control over what happens on other machines, nor what happens if one of its pieces of hardware is accessed via some mechanism outside the operating system’s control. But how can we expect the operating system to protect something when the system does not itself control access to that resource? The an- swer is to prepare the resource for trouble in advance. In essence, we assume that we are going to lose the data, or that an opponent will try to alter it improperly. And we take steps to ensure that such actions don’t cause us problems. -
System Integration in Web 2.0 Environment
Masaryk university, Faculty of Informatics Ph.D. Thesis System Integration in Web 2.0 Environment Pavel Drášil Supervisor: doc. RNDr. Tomáš Pitner, Ph.D. January 2011 Brno, Czech Republic Except where indicated otherwise, this thesis is my own original work. Pavel Drášil Brno, January 2011 Acknowledgements There are many people who have influenced my life and the path I have chosen in it. They have all, in their own way, made this thesis and the work described herein possible. First of all, I have to thank my supervisor, assoc. prof. Tomáš Pitner. Anytime we met, I received not only a number of valuable advices, but also a great deal of enthusiasm, understanding, appreciation, support and trust. Further, I have to thank my colleague Tomáš Ludík for lots of fruitful discussions and constructive criticism during the last year. Without any doubt, this thesis would not come into existence without the love, unceasing support and patience of the people I hold deepest in my heart – my parents and my beloved girlfriend Míša. I am grateful to them more than I can express. Abstract During the last decade, Service-Oriented Architecture (SOA) concepts have matured into a prominent architectural style for enterprise application development and integration. At the same time, Web 2.0 became a predominant paradigm in the web environment. Even if the ideological, technological and business bases of the two are quite different, significant similarities can still be found. Especially in their view of services as basic building blocks and service composition as a way of creating complex applications. Inspired by this finding, this thesis aims to contribute to the state of the art in designing service-based systems by exploring the possibilities and potential of bridging the SOA and Web 2.0 worlds. -

UNLOCKING THE FIFTH AMENDMENT: PASSWORDS AND ENCRYPTED DEVICES Laurent Sacharoff* Each year, law enforcement seizes thousands of electronic devices— smartphones, laptops, and notebooks—that it cannot open without the suspect’s password. Without this password, the information on the device sits completely scrambled behind a wall of encryption. Sometimes agents will be able to obtain the information by hacking, discovering copies of data on the cloud, or obtaining the password voluntarily from the suspects themselves. But when they cannot, may the government compel suspects to disclose or enter their password? This Article considers the Fifth Amendment protection against compelled disclosures of passwords—a question that has split and confused courts. It measures this right against the legal right of law enforcement, armed with a warrant, to search the device that it has validly seized. -

Similar to the well-known and -researched TOR project, I2P (Invisible Internet Project) aims to provide this inside its own network. But how secure and protected can a user feel when using I2P? The main objectives of this thesis were to create I2P Observer, a Java program which gathers and publishes information about the I2P network, and to evaluate possible attacks on the software.
