Formal Aspects of Mobile Code Security
FORMAL ASPECTS OF MOBILE CODE SECURITY RICHARD DREWS DEAN ADISSERTATION PRESENTED TO THE FACULTY OF PRINCETON UNIVERSITY IN CANDIDACY FOR THE DEGREE OF DOCTOR OF PHILOSOPHY RECOMMENDED FOR ACCEPTANCE BY THE DEPARTMENT OF COMPUTER SCIENCE JANUARY 1999 c Copyright by Richard Drews Dean, 1998. All Rights Reserved Abstract We believe that formal methods of all kinds are critical to mobile code security, as one route to gaining the assurance level necessary for running potentially hos- tile code on a routine basis. We begin by examining Java, and understanding the weaknesses in its architecture, on both design and implementation levels. Iden- tifying dynamic linking as a key problem, we produce a formal model of linking, and prove desirable properties about our model. This investigation leads to a deep understanding of the underlying problem. Finally, we turn our attention to crypto- graphic hash functions, and their analysis with binary decision diagrams (BDDs). We show that three commonly used hash functions (MD4, MD5, and SHA-1) do not offer ideal strength against second preimages. The ability of a cryptographic hash function to resist the finding of second preimages is critical for its use in digi- tal signature schemes: a second preimage enables the forgery of digital signatures, which would undermine confidence in digitally signed mobile code. Our results show that modern theorem provers and BDD-based reasoning tools are effective for reasoning about some of the key problems facing mobile code security today. iii Acknowledgments My advisor, Andrew Appel, offered sure guidance through what turned out to be an exceptionally smooth journey through graduate school. -

Prezentacja I Zastosowanie Systemu Internetowych Pomiarów Obrazów Fotogrametrycznych
Artur Janowski Zygmunt Paszotta Jakub Szulwic PREZENTACJA I ZASTOSOWANIE SYSTEMU INTERNETOWYCH POMIARÓW OBRAZÓW FOTOGRAMETRYCZNYCH Streszczenie. W referacie zaprezentowane zostają funkcjonujące rozwiązania powstałe w ramach badań i prac doktorskich, a odnoszące się do rozwiązywania zadań fotogrametrii lotniczej w środowisku internetowym. Pierwotny zamysł systemu internetowych pomiarów obrazów fotogrametrycznych (SIPOF) zrodził się w projekcie badawczym prowadzonym w zespole dra hab. Zygmunta Paszotty, prof. UWM, na Uniwersytecie Warmińsko-Mazurskim w Olsztynie. Zasadnicze badania były realizowane w ramach studiów nad rozprawami doktorskimi autorów. Efekty badań zostały wdrożone w formie funkcjonującego systemu umożliwiającego realizację internetowych pomiarów na zdjęciach fotogrametrycznych nazwanego SIPOF. Referat jest skróconym przewodnikiem po systemie; prezentuje jego funkcjonalność oraz przedstawia możliwości wykorzystania w edukacji, nauce i gospodarce. SIPOF był prezentowany w ośrodkach edukacyjno-badawczych w Polsce oraz zagranicą i spotkał się z zainteresowaniem podmiotów gospodarczych. Komercjalizacja pracy naukowej zaowocowała dalszą koncepcją udostępniania fotogrametrycznych opracowań rastrowych jako nośników informacji kartometrycznej dla użytkownika specjalistycznego i masowego. Przedstawienie funkcjonującego systemu internetowych pomiarów fotogrametrycznych opartego przede wszystkim na kliencie informatycznym implementowanym w graficznej przeglądarce internetowej stanowi tło dla oczekiwań , jakie pokładane są przez użytkownika -
