An Incentive-Based Secure Accounting Scheme for Converged Networks
Meng Wu · Journal of Nanjing University of Posts and Telecommunications · 2008
The issue of secure charging must be solved before converged networks are employed in commercial applications.In order to solve this problem,a secure incentive-based accounting scheme for converged networks is proposed.The scheme utilizes charging receipt to thwart non-reputation attacks.Meanwhile,Message Authentication Code(MAC) and stream cipher mechanism are introduced to offer information security.Security analysis shows that the proposed scheme not only grants the existence of selfish nodes to meet their rational demand,but also is robust enough to prevent various active attacks(e.g.,denial of services(DoS),replay attacks,tampering attacks and impersonation attacks).Finally,simulation analysis indicates the influence of proposed scheme on routing stability and node cooperation in low overhead.
