Ask HN: Many Private Keys, One Public Key
Is there an algorithm that allows for many Private Keys, but only one Public Key?

In key-insulated cryptography, there are many private keys with different indexes and a single, fixed public key. When the trust model includes multiple Certification Authorities (CAs), it can be used to shorten the verification path and mitigate the damage caused by the compromise of a CA’s private key. Really, people will want more information to give better responses.
