I wish to find an asymmetric encryption algorithm that supports key derivation, BIP0032 style. Meaning that I have some SEED [PRIV] and I give someone some public data [PUB], then given new public data X (serial number for example), I can generate a new private key and this someone may generate the corresponding public key.

  • It is important that given one (or more) of those private keys, you may not deduce the other private keys.

Do you know such a scheme? Thanks!

  • $\begingroup$ Welcome! Please clarify which scheme you want to use - RSA? DSA? ECDSA? $\endgroup$

  • $\begingroup$ Hi Tal, thank you for the kind reply, I prefer Elliptic Curve cryptography, but any encryption scheme that will hold my requirement will do. $\endgroup$ Jan 14 '19 at 10:11
  • $\begingroup$ Which part of the bitcoin protocol pointed to does not meet your demands? Have you looked at this similar Q/A? Note that most of our users are not BitCoin aficionados, so that could be the reason for the lack of answers. $\endgroup$
