Mobile Agent Security
This chapter focuses on a very important part of mobile agent research—
security. Many research groups worldwide have focused on security aspects
of mobile agents and published a large number of papers. In fact, most
research in the area of mobile agents was done in security issues. However,
the actual state-of-the-art technology has not yet reached a level that could
provide an applicable set of best practices with industrial strength. We really
talk about basic research and miss out, in most cases, on a complete frame-
work of integrated concepts and tools. We cannot provide such an integrated
framework in this book; our goal is to provide an overview of the cur-
rent state-of-the-ar t technology as it relates to our perspective on mobile
agents.
First, we introduce security requirements for computer systems in general.
We also discuss some basic cryptographic techniques, such as encryption,
signing, and hash values. We then concentrate on the problems specific to
mobile agents and present the currently available solutions.
