Secure Multi-Source Network Coding Against Pollution Attack
Xiaopeng Wang · Journal of Lanzhou Jiaotong University · 2012
The multi-source network code files are vulnerability to pollution attack in the transmission process,for this reason a novel secure signing program is presented accordingly.First,the multi-source network coding signature rules are presented,then combined with security auxiliary algorithm,the anti-pollution attack is constructed based on the discrete logarithm problem.The security,correctness and completeness of our scheme are discussed in this paper.The security of our scheme relies on difficulty of the discrete logarithm problem.Compared with the known approaches,the new scheme has the characteristics of short signature length,strong practical security model and low computational complexity.
