Security issues in the data link layer are not properly explained while network security problems in other layers of OSI model are studied and addressed. In this paper, the authors propose a new security inter-layering structure to secure data link layer in Internet protocol over Ethernet networks. In the data link layer, they have proposed to use secure namespaces instead of Media Access Control(MAC) to identify network devices, which provides a mean to bind data link layer with other layers of OSI model very securely. Present network structure provides a link to link security and the key establishment protocol to generate security parameters in this layer.
