Bytecode verification is a crucial security component for Java applets, on the Web and on
embedded devices such as smart cards. This paper reviews the various bytecode …

The origin of this book goes back to the Dagstuhl seminar on Logic for System Engineering,
organized during the first week of March 1997 by S. Jiihnichen, J. Loeckx, and M. Wirsing …

We present a system for extending standard type systems with flow-sensitive type qualifiers.
Users annotate their programs with type qualifiers, and inference checks that the …

We review the existing literature on Java safety, emphasizing formal approaches, and the
impact of Java safety on small footprint devices such as smartcards. The conclusion is that …

The goal of typed assembly language (TAL) is to provide a low-level, statically typed target
language that is better suited than Java bytecodes for supporting a wide variety of source …

This article presents a novel approach to the problem of bytecode verification for Java Card
applets. By relying on prior off‐card bytecode transformations, we simplify the bytecode …

In previous work, we presented a Typed Assembly Language (TAL). TAL is sufficiently
expressive to serve as a target language for compilers of high-level languages such as ML …

This paper presents STAL, a variant of Typed Assembly Language with constructs and types
to support a limited form of stack allocation. As with other statically-typed low-level …

Abstract The Java Virtual Machine executes bytecode programs that may have been sent
from other, possibly untrusted, locations on the network. Since the transmitted code may be …

Security of mobile code is a major issue in today's global computing environment. When you
download a program from an untrusted source, how can you be sure it will not do something …
