How to encrypt the activation signal for my kill-switches to make them impossible to hijack

Dragons are awesome, but they're still vulnerable thanks to their low-numbers and a certain type of people...

So, to prevent those from killing even a single dragon I came up with the wedding rings of death. They kill by releasing a poison straight into the vitals (usually the brainstem), they're wrapped around. Tampering will also trigger the ring.

The important thing is that they can be activated remotely via a radio signal. They're also already and will always be present in every living creature (except dragons), as the rings double as Von Neumann machines (they can replicate themselves).

The problem is that means any haxxor could attempt to make these things go off. And there's a LOT of these rings, and so a broadcast brute-force attack has a higher chance of activating one of them.

I need a way to encrypt the activation signal for every occasion in a way that it's near impossible to crack or brute-force it. Assume you have unlimited computing capacity, but less resource-intensive solutions that work just as well are more preferable.

Quantum computers are rare and exclusive to the creators of the rings, however, neural networks have made a step up from composing 10-hour rap music and can be a significant threat.
