Definition
Uncoordinated Frequency Hopping Spread Spectrum (UFHSS) is a spread spectrum communication technique where the sender and the receiver hop between communication channels that they choose randomly and independently from a public set of channels. Neither the receiver nor the attacker knows the channel sequence used by the sender prior to communication. It was introduced by Strasser, Popper, Capkun and Cagalj.
Background
Spread Spectrum (SS) techniques represent a common way to achieve jamming-resistant communication. Spread spectrum techniques use data-independent, random sequences to spread a narrowband information signal over a wide (radio) band of frequencies. Under the premise that it is hard or infeasible for an attacker to jam the entire frequency band, the receiver can correlate the received signal with a replicate of the random sequence to retrieve the original information...
