A Multi-agent Security Architecture

This paper presents a multi-agent security architecture, which utilizes the agent characteristics to cater for security processes in online communications. The multilayer communication approach (MLC) is used to determine the security processes, which uses cryptography protocols to secure data and communication channel. Agents are skilled to perform certain tasks. At the sender´s host, agents interact with each other to secure a message to be sent to the recipient, including encryption, digital signature, and hash code. A mobile agent is used to carry the encrypted messages as well as the agent´s code to the recipient´s host. Our approach also provides mechanisms to verify the authenticity, confidentiality and the integrity of the code and data that arrived at the recipient´s host. The message and the code are authenticated, the code is executed to perform tasks to recover the plaintext.
