Honey Chatting: A novel instant messaging system robust to eavesdropping over communication

Joo-Im Kim and Ji Won Yoon

Abstract: There have been many efforts to strengthen security of Instant Messaging (IM) system. One of the typical technologies is the conventional message encryption using a secret or private key. However, the key is fundamentally vulnerable to a bruteforce attack, causing to acquire the original message. In this respect, a countermeasure was suggested as the way to generating plausible-looking but fake plaintexts, which is called Honey Encryption (HE). In this paper, we present a HE-based statistical scheme and design a Honey Chatting application, which is robust to eavesdropping. Besides, we verify the effectiveness of the Honey Chatting by comparing the entropy of decrypted messages through experiments.
