Fine-Grained Security Model in Multi-Agent Communication

Multi-Agent systems (MAS) have been used widely in open distributed networks, such as e-commerce applications for Internet. An environment such as the Internet can be considered unsafe. Thus, multi-agent systems should have security mechanisms, such as integrity, authentication, and confidentiality. Traditional security technologies just satisfy coarse grained security requirements. Agents may use a FIPA standard called RDF, which is a message content standard in XML language. Using this standard, agents can exchange messages in XML format.
