A survey of security in multi-agent systems

Abstract

Multi-agent systems (MAS) are a relatively new software paradigm that is being widely accepted in several application domains to address large and complex tasks. However, with the use of MAS in open, distributed and heterogeneous applications, the security issues may endanger the success of the application. The goal of this research is to identify the security issues faced by MAS and to survey the current state of the art of this field of knowledge. In order to do it, this paper examines the basic concepts of security in computing, and some characteristics of agents and multi-agent systems that introduce new threats and ways to attack. After this, some models and architectures proposed in the literature are presented and analyzed.
