In this paper, we propose a method of selecting users randomly from the Chord-based P2P network. The server sends a token with random hash value destinations in the P2P network, and the user nodes forward the token. The forwarding nodes and the destination nodes will be the winners of the selection. However, malicious nodes may prevent random selection over the P2P network. By applying five rules in the selection process, the proposed method mitigates the negative impacts caused by malicious nodes. We present the feasibility of random selection using the proposed method through our simulation results. The simulation results indicate that the proposed method will work where the percentage of malicious nodes in the P2P network is around 1% or less and the competitive ratio for winning the selection is around 100 or more.
