In the transhumanist system, ie a transhuman's body, there are many more opportunities for the creation of statistically pure entropy. Many of the body's systems can be tapped for the chemical nature of their various exchanges. The collection of waste in the gastrointestinal system, movement of lymph, fluctuating core temperature, degrees of motion, amount of neural leakage, the list of sources in the chaotic system that is the human body goes on for pages, and one would only need to interview a doctor for more information. So, when paired with a post or transhuman bioelectronical systems would provide a large amount of entropy for encrypted systems.
