Agents come and go, and interact with strangers.
Assumptions about security and general trustworthiness of agents and their deployers are inadequate in this context. In this paper, we present the design of a security infrastructure applicable to MASs in general. Our design addresses both security threats and trust issues. In our design, we have mechanisms for ensuring secure communication among agents and secure naming and resource location services. For updates and comments, please see these instructions .
