I like the psychology you put into that. The hacker mentality will also catch the imagination

comment Possible to use an accumulator to “license” or restrict the qty of certificates being used?
That is a great way of framing the question. I appreciate the sentiment too, and do appreciate the constructive comments and thoughts. I will leave the crypto as a black box as you suggest. I'm excited to see the other answers here (multi show, and nonce)

What if the prime was simply a "factor" in the private key? e.g. CA-issued prime * client issued prime = a non prime number used as the private key

YEa, I thought about that after I posted... perhaps the parent could sign a list of pre-approved primes. I'm trying to figure out which crypto would support this feature..
