New client puzzle approach for DoS resistance in ad hoc networks

Michalas, A., Komninos, N., Prasad, N. R. & Oleshchuk, V. A. (2010). New client puzzle approach for DoS resistance in ad hoc networks. Proceedings 2010 IEEE International Conference on Information Theory and Information Security, ICITIS 2010, pp. 568-573. doi: 10.1109/icitis.2010.5689528


In this paper we propose a new client puzzle approach to prevent Denial of Service (DoS) attacks in ad hoc networks. Each node in the network first solves a computational problem and with the solution has to create and solve a client puzzle. By combining computational problems with puzzles, we improve the efficiency and latency of the communicating nodes and resistance in DoS attacks. Experimental results show the effectiveness of our approach.
