Key Management Technology Suitable for Ethernet

Ethernet technology,for its openness,economy and easy use etc.,is applied more and more widely,and how to transmit the classified information securely and reliably on Ethernet becomes a problem demanding prompt solution. Thus the data protection devices and systems based on Ethernet emerge as the times demand. In accordance with the communication mode of and the safety threat on Ethernet network,the general model of group key management is studied,and the key management design suitable for point-to-multipoint communication of Ethernet is proposed. The design provides a feasible program for the development of Ethernet data protection devices and systems.
