Anti-Jamming Frequency Hopping Techniques for Secure Multicast Communications
نویسندگان
چکیده
We address the problem of jamming mitigation of multicast communications in multi-channel ad hoc networks. Specifically, we develop two frequency hopping (FH) techniques for establishing multicast communications. These techniques, denoted by KFH and CFH, address the two following problems. First, establishing multicast communications in the presence of a control-channel jamming attack. Second, redistributing the secret keys (i.e., PN codes) once the current keys have been exposed by a smart eavesdropping jammer. Our techniques are distributed, do not incur any additional message exchange overhead, work in the absence of node synchronization, and maintain the multicast group consistency.

Jamming attacks have been studied as wireless security threats disrupting reliable RF communication in a wireless network. Existing countermeasures often make use of spread-spectrum techniques such as Frequency Hopping Spread Spectrum and Direct Sequence Spread Spectrum [3]. Communication parties rely on a pre-shared common key (hopping sequence or spread code) which is unknown to the jammer, t...
متن کاملA Highly Efficient Secure Communication Interface : Collision - Free Frequency Hopping ( CFFH )
Frequency hopping systems have been widely used in military communications to prevent hostile jamming, interception and detection. In traditional frequency hopping (FH) systems, the transmitter hops in a pseudo-random manner among available frequencies according to a pre-specified algorithm, and the receiver operates accordingly in exact synchronization with the transmitter's hopping pattern. I...

This is Part I of a two-part paper that considers antijamming system design in wireless networks based on messagedriven frequency hopping (MDFH), a highly efficient spread spectrum technique. In this paper, we first analyze the performance of MDFH under hostile jamming. It is observed that while MDFH is robust under strong jamming, it experiences considerable performance losses under disguised ...
