A Survey of Security Techniques to Protect Mobile Agent from Malicious Host

Mobile agent system is a new paradigm of distributed computing,with some prominent advantages,but agent-based applications is impeded by the question of security.The security of mobile agent can be classified into two catalogs: host security and agent security.This paper surveys the latter question,and describes the threats which mobile agents are confronted with on malicious hosts and security strategies should be adopted.It emphasizes on presenting of every typical technical countermeasures and gives relevant evaluations.
