Selected security aspects of agent-based computing

The paper presents selected security aspects related to confidentiality, privacy, trust and authenticity issues of a distributed, agent-based computing. Particular attention has been paid to authenticity of and trust in migrating mobile agents executables, agent´s trust in runtime environment, inter agent communication and security of agent´s payload. Selected attack vectors against agent-based computing were described and risk mitigation methods and strategies were proposed and discussed based on presented cryptography measures. In summary expected effectiveness of proposed countermeasures was described.
