Flexocleaners.com and The Sierra Club urge the Environmental Protection Agency (EPA), state agencies and corporations to eliminate the use of the cleaning agent, nonylphenol ethoxylates (NPEs), in the industrial and domestic laundry detergent used in the United States. NPE metabolites often pass through wastewater treatment plants at a concentration that has been shown to cause harmful effects ...

Mobile agents are a distributed computing paradigm based on mobile autonomous programs. Mobile applications must balance security requirements with available security mechanisms in order to meet application level security goals. We introduce a trust framework to reason about application security requirements, trust expression, and agent protection mechanisms. We develop application security mod...

The paper describes the agent-based approach and software environment (based on OMNeT++ INET Framework) developed for simulation of distributed defense mechanisms which can be deployed in the Internet for counteraction to computer network attacks. According to the approach suggested, the cybernetic counteraction of “bad guys” and security systems is represented by the interaction of different a...

This work defines a security scheme, based on SPKI/SDSI chains of trust, for protecting mobile agent platforms in large-scale distributed systems. The scheme is composed by a protocol of mutual authentication, a mobile agent authenticator and a mechanism for the generation of protection domain. Due to the flexibility of the SPKI/SDSI certificate delegation infrastructures used, the proposed sch...

Mobile code systems provide a exible and powerful platform to build distributed applications in an Internet scale, but they rise strong requirements from the security point of view. Security issues include authentication of the di erent remote parties involved and protection of the execution environments from malicious agents. Nonetheless, the most di cult task is to protect roaming agents from...

The main challenge when deploying mobile agent environments pertains to security issues concerning mobile agents and their executive platform. This paper proposes a secure protocol which protects mobile agents against attacks from malicious hosts in these environments. Protection is based on the perfect cooperation of a sedentary agent running inside a trusted third host. Results show that the ...
