A Modified Algorithm to Verify Integrity and Authentication of Data in Virtual Networks
Network virtualization is a technology that enables the creation of logically isolated network partitions over shared physical network infrastructures so that multiple heterogeneous virtual networks can simultaneously coexist over a shared infrastructure. Network Virtualization is considered as a challenging approach to overcome the current ossification of the Internet. A major issue in the Network Virtualization is an efficient virtual network embedding deals with the efficient mapping of virtual nodes and virtual edges on substrate network resources. In this paper, the authors propose the algorithm that verifies the integrity and authenticity of the packet transmitted from source to destination. The algorithm detects the loss of data if any while transmission and also identifies damage to the packet.
