Abstract: Method and system of guising communication using a chatter signal is disclosed. In one embodiment, a method includes communicating a chatter signal generated by a first node of a network to a second node based on the communication protocol of the network to guise a true signal of the first node communicated to the second node of the network, and processing the true signal communicated to the second node while dispensing with the chatter signal communicated to the second node based on the communication protocol of the network. The method may also include padding the chatter signal and/or the true signal with pseudorandom bits to make a size of the chatter signal equal to a size of the true signal. Moreover, the method may include guising a key exchanged between the first node and the second node with the chatter signal.
