Abstract
Because of the popularity of wireless technology, jamming attack is one of the most critical issues in wireless networks. Wireless jamming attack is one type of denial-of-service attacks where attackers send malicious messages or signal on a legitimate channel by causing intentional interference in the network. In order to avoid jamming attacks, various jamming defense schemes have been proposed. One of the popular methods is a channel-hopping scheme. However, the main challenge of this method is generating a common channel number between the users and the access point without leaking that information to the jammer. We propose a new channel-hopping scheme where the access point shares a separate key with each user to isolate the damage on the network when a key has been compromised, while maintaining high throughput and fairness. We evaluate the proposed scheme through experiment on a test bed.
