RPKI uses authentication not confidentiality. There is no encryption taking
place, other than the signatures on the certificates etc.

Which do not exist (yet).

No they're not. It's just not possible or indeed necessary to duplicate
everything at large scale. Perhaps with a large amount of filtering,
certain flows would be captured, but in the days of pervasive TLS, this
seems less and less worthwhile.

None of this is relevant to RPKI (ROV) at all. In fact, it reads like the
fevered dreams of a cyber security research student. What's your point
regarding your message? ROV does not use (nor needs) encryption.
