applying chaos to a signal using matlab/simulink

Hello, my name is Alex and I just started working on my master's thesis which is basically a transmission system based on chaotic signals. My super insists on making a simulink example of the signal encrypted with chaos and decrypted in the end, drawing every conclusion possible out of this experiment.
I've searched the web high and low and I couldn't find anything useful, so if anyone could point me in the right direction I would very much appreciate it:
1. Where can I find an example of a chaos function in matlab and how can I add it to my signal in simulink.
I hope this question doesn't sound stupid, but at this point i'm getting desperate, thank you for your time ^^ .

A pseudorandom sequence is a chaotic signal.
rand - This gives you a pseudorandom number with a top-hat distribution of values. randn - This gives you a pseudorandom number with a normal distribution.
rand(1000000,1) % This gives you 1 million pseudorandom numbers...

In Simulink, you can do this using the Uniform Random Number block, Random Number block or Band-Limited White Noise block, and sum it to the input signal.
