Science And Security Watch: A Threat To The United States From Foreign Graduate Students Training In Physics?, Ibpp Editor Jul 1999

Science And Security Watch: A Threat To The United States From Foreign Graduate Students Training In Physics?, Ibpp Editor

International Bulletin of Political Psychology

This article critiques concerns of some United States (US) security analysts that foreign graduate students in physics who train at universities within the US present security vulnerabilities for the US.

Java’S Insecure Parallelism, Per Brinch Hansen Jan 1999

Java’S Insecure Parallelism, Per Brinch Hansen

College of Engineering and Computer Science - Former Departments, Centers, Institutes and Projects

The author examines the synchronization features of Java and finds that they are insecure variants of his earliest ideas in parallel programming published in 1972-73. The claim that Java supports monitors is shown to be false. The author concludes that Java ignores the last twenty-five years of research in parallel programming languages.


Formal Analysis Of A Secure Communication Channel: Secure Core-Email Protocol, Dan Zhou, Shiu-Kai Chin Jan 1999

Formal Analysis Of A Secure Communication Channel: Secure Core-Email Protocol, Dan Zhou, Shiu-Kai Chin

Electrical Engineering and Computer Science - All Scholarship

To construct a highly-assured implementation of secure communication channels we must have clear definitions of the security services, the channels, and under what assumptions these channels provide the desired services. We formally define secure channel services and develop a detailed example. The example is a core protocol common to a family of secure email systems. We identify the necessary properties of cryptographic algorithms to ensure that the email protocol is secure, and we verify that the email protocol provides secure services under these assumptions. We carry out the definitions and verifications in higher-order logic using the HOL theorem-prover. All our …
