Abstract: With the application of mobile agent technology in distributed computing, mobile agent systems encounter numerous security and software engineering challenges. To prevent malicious or unauthorized attacks from the third party entities, the method of protection of agent’s data and code was investigated, and a new mobile agent’s architecture was designed, which was composed of data wrapping all executable code intended for a given platform and explicit agent code in charge of transporting and handling the above data. The data-code split could co-exist with other architectures already proposed to improve platform interoperability. Finally, to protect data from agent’s code modification, public key decryption mechanism and agent authentication mechanism was analyzed. To protect code from injection of malicious data, data protection mechanism was proposed by improving the structure of data.
