A procedure for removing a pulbic key for the anonymous list #1

There could be situations where citizens had lost their ID cards and thus needs to get a new one. How would one deal with the public key in the public ledger?

A possible solution seems to be:

Put in the anonymous public key ledger also the expiration date of the ID card and thus of the public key.
Ask citizen to sign his ID data with his card and keep the signature in secret to prove his relation with the public key.

An ultimate procedure for deregistration can be achieved through rebraiding starting from the base generator where the individual is removed. This can be done when a certain threshold is reached and thus would not be instantiated every time.

Also, a procedure for sharding keys between different parties could be introduced. This problem is elegantly solved with iCloud when E2E encryption is selected.
