Abstract

   Due to the computation and storage limitations of constrained-node
   networks, it is costly to apply those security mechanisms based on
   public key algorithm. This document proposed a subliminal channel
   hiding communication method, which can provide message
   authentication service and protect the transmission of the sensitive
   data.

1. Introduction

   In the existing networks, the processing of the sensitive data has
   mainly used a variety of encryption technologies, and the sensitive
   data is transmitted through the public channel. The attacker could
   easily detect the communication process, hence, the man-in-middle
   attack, the DoS attack or the Sybil attack can be applied to
   interfere the communication, which makes the legal receiver cannot
   obtain the encrypted sensitive data, and leads to the failure of the
   communication process eventually.

   The subliminal channel hiding communication is to hide the sensitive
   data into the ordinary data. The attacker is hard to analyze whether
   there is any sensitive data in the ordinary data. In this way, the
   transmitted ordinary data would not cause attacker's attentions and
   doubts. The subliminal channel hiding communication decreased the
