Abstract:

   Using a distinct holder-binding key for each Credential improves
   unlinkability, but generating and storing many keys in a Wallet
   secure area can be expensive or impossible.  This document defines a
   way to derive unlinkable P-256 Credential keys from one protected
   parent key while retaining the parent's key-protection properties.
   It specifies this mechanism as an extension to OpenID for Verifiable
   Credential Issuance (OpenID4VCI), allowing the Issuer to derive each
   child public key while only the Wallet can use the corresponding
   child private key.
