I suggest you take a look at these I-Ds:

* https://tools.ietf.org/html/draft-gont-numeric-ids-history
* https://tools.ietf.org/html/draft-gont-numeric-ids-generation
* https://tools.ietf.org/html/draft-gont-numeric-ids-sec-considerations

They are meant to provide analysis and solutions for this an other
numeric IDs.

FWIW, there's an ongoing call for adoption (please see here:
https://mailarchive.ietf.org/arch/msg/pearg/YlTn3VlnwFbnJ0IgNLTtLwg6W0c), on
the PEARG list (https://www.irtf.org/mailman/listinfo/pearg).

Thanks!

Cheers,
