The Protects Of Active Packets In Aetive Network

Active Network is a new kind of network with great proactively and flexibility. It overcomes the traditional network shortcomings. First, the traditional network has bad expansibility. Second, it transmits data packet passively. Third, it issue agreements and service difficultly. The concept of Active Network has brought a huge transformation of the development direction of network.By introducing the limitations of traditional network, the article develop the concept of active network; It is researched that the features,System structure and secure problem of Active Network; The active codes'secure problems and Secure Computation are discussed. We designed the module of garbled circuit. We programmed and accomplished a comparative price system. It protects the private message of participants by using garbled circuit. Participants of the garbled circuit have no use for exchanging message. The module greatly reduced the cost of network. It protects active codes by pure software protection.
