Agent-based computing represents a promising paradigm for distributed computing. Unfortunately the lack of security is hindering the application of this paradigm in real world applications. The protection of malicious hosts is considered the most difficult security problem to solve in mobile agent systems. In this paper we provide a mechanism that aims to solve the problem of the malicious hosts....
As security is always a major concern in most of the networked computer systems, embedded systems should provide security features to defend the attack and protect the confidential and sensitive data. Many Trojan Horses and viruses use the security holes of exception to trigger attack, such as buffer overflow attack. Although most embedded systems rely on the programmer, the compiler or the third-party...
Conventional methods supporting Java binary security mainly rely on the security of the host Java Virtual Machine (JVM). However, malicious Java binaries keep exploiting the vulnerabilities of JVMs, escaping their sandbox restrictions and allowing attacks on end-user systems. Administrators must confront the difficulties and dilemmas brought on by security upgrades. On the other hand, binary rewriting...
To resolve the security problems of Java mobile programs, we adapted the technique of type-level abstract interpretation usually applied to verify the bytecode correctness to check the mobile program statically whether it impairs the host confidentiality. Instead of data types, our approach abstractly executes the mobile program at the level of security-level. Based on maintaining a distribution map...
