| Abstract: | The realtime performance is one top concern of VPN Gateway. In order to solve the problem, a novel approach to design VPN security gateway based on DSP was prsented . With dual TMS320C62x chips, a applicable broadband VPN Gateway has been implemented. The functional framework of the presented VPN gateway, the communication between Linux kernel and DSP,the implementation method for encryption algorithm, etc. were given in detail. |
