Establish A Symmetric Key: KDF Based On Shared Secret And Random Salt Or Key Wrapping ✺

The administrator establishes a shared secret common to every user of the system. This secret is stored in every HSM belonging to the users or to the administrator. When a key must be generated, the administrator computes it with PBKDF2 using the common secret and a random salt.. HMAC-Based Extract-and-Expand Key Derivation Function (HKDF) . ...
