As wireless networks become more pervasive, the amount of the wireless data is rapidly increasing. One of the biggest challenges is how to store these data. To address this challenge, distributed data storage in wireless networks has attracted much attention recently, as it has major advantages over centralized approaches. To support the widespread adoption of distributed data storage, secure data storage must be achieved. In this work, the authors study the frequency-based attack, a type of attack that is different from previously well-studied ones, that exploits additional adversary knowledge to crack the encrypted data. To cope with frequency-based attacks, the straightforward 1-to-1 substitution encryption functions are not sufficient.
