Abstract
Methods are provided for using a hardware module connectable to multiple computer systems, where the multiple computer systems are connectable to a server within a common network. The method includes: providing a network address of the server in persistent memory of the hardware security module; providing an encrypted secret entity in the persistent memory of the hardware security module; providing a private key in the persistent memory of the hardware security module; and based on the hardware security module being connectable to one of the computer systems, the method includes: establishing a secure connection between the hardware security module and the server; retrieving, via the secure connection, a wrapping key from the server and storing it in volatile memory of the hardware security module; and decrypting the encrypted secret entity with the wrapping key and storing the decrypted secret entity in the volatile memory of the hardware security module.
