Abstract :
A VoIP-based dynamic password distribution scheme is described in this paper. For the respective drawbacks of the conventional dynamic password distribution schemes, a novel solution is proposed, the dynamic password is obtained by the user through making a call. The distribution system is based on a VoIP subsystem, of which the call control is modified to reduce the cost. The VoIP subsystem is designed on the basis of asterisk and SIP protocol, both of which have outstanding advantages such as expansibility, business-oriented and so on. The architecture, workflow implementation and application of the dynamic password distribution system will be discussed in this paper.
