Secure Programming Languages Based on Mobile Code

点击翻译按钮获取中文摘要

We studied secure programming languages based on mobile code. We worked on essential research issues in security of programming languages and system software from both theoretical and practical aspects. First we gave a systematic solution to problems in programming languages, which is the most important element in software development. The solution is not ad-hoc but based on a solid theory. Furthermore, we addressed research issues in system software with a systematic solution based on deep understanding of target systems. The results of this research include a secure compiler for the C programming language (Fail-Safe C), an interface definition language for Fail-Safe C, an operating system that guarantees security using type systems (Kernel Mode Linux), a system that defends networks against distributed denial of service attacks (MovingFirewall), cryptographic lambda calculus, regular expression types for string operations, self-repairing reference monitors, a fine-grain access control mechanism between program modules, programming languages that support the description of mobile code (JavaGO and JavaGoX), object usage analysis for Java, efficient regjon-based memory management for a dynamical ly-typed programming language Scheme, and a type system for access control in distributed computation. The results are highly evaluated by internat ional communit of computer science. This research had a significant impact on academic and industrial fields by releasing three software and publishing about 30 refereed papers. We received four prestigious awards including the best paper award from Japan Society for Software Science and the best technology award from Nikkei Business Publications Inc.
