Abstract: This paper presents an encrypted multi-component management model for software rights protection under limited hardware resource environment. Downloading, updating and deleting the encrypted multi-component are realized through combining virtual machine (VM) technology and layered function strategy. The security measures adopted in this model are put forward. The model is of high security and good platform portability, and is equipped with software development mode supporting multi-participation.
