generate a sequence of points. Third, starting from the first point in the sequence, the coordinates of a point are converted into an unique integer, indicating the new location where the first element of array is to be put in the output array. Now considering the array element from the second to the last, the abovementioned process is repeated till the last array element is shuffled. Finally, the output array contains the shuffled message. Please note that the random shuffling function is executed differently in every communication session. This is because the wireless medical device, control node, and cloud server will compute a new CRP pair during the process of mutual authentication and session key establishment. Since the CRP pair is used as the initial condition of Tinkerbell map and a minor change of initial condition in the Tinkerbell map will cause the generation of distinct sequence of points (see more details about Tinkerbell map’s features in Section III), the random shuffl
