Mobile Code Security Techniques
Jonathan T. Moore · 1998
This paper presents a survey of existing techniques for achieving mobile code security, as well as a representative sampling of systems which use them. In particular, the problem domain is divided into two portions: protecting hosts from malicious code; and protecting mobile code from malicious hosts. The discussion of the malicious code problem includes a more in-depth study of the Java security model, as well as touching upon several other systems. The malicious host problem, however, is much more difficult to solve, so our discussion is mostly restricted to ongoing research in that area. 1 Introduction The recent explosion of the Internet, and in particular, the World Wide Web, offers an astounding amount of interconnected computing resources. However, for most users, their use of Internet resources is primarily limited by bandwidth. In particular, especially in home computers, there are many CPU cycles to spare in comparison to the rate at which data can be retrieved. This suggest...
