This document contains a security reference model for digital currency hardware wallets and requirements and recommendations regarding the security of digital currency hardware wallets. It includes security requirements for (i) data management, (ii), communication, and (iii) access control requirements between different modules of the hardware wallets; security requirements for the running environment of the software operating in the hardware wallet; and security policies for service operation of the hardware wallet.
