3.6.2 Cryptographic Key Storage

CSPs, IdPs (including subscriber-controlled wallets), and RPs SHALL store all signing keys, decryption keys, and symmetric keys in a secure fashion. Cryptographic key storage is subject to applicable [FIPS140] requirements, including applicable tamper resistance requirements.

Some circumstances require the cryptographic keys to be stored in a non-exportable manner, such as reaching FAL3 with a subscriber-controlled wallet on a subscriber’s device (see Sec. 5.4.1). To be considered non-exportable, key storage SHALL either be a separate piece of hardware or an embedded processor or execution environment, such as a secure element, trusted execution environment (TEE), or trusted platform module (TPM). These hardware modules or embedded processors are separate from a host processor, such as the CPU on a laptop or mobile device. Non-exportable key storage SHALL be designed to prohibit the export of the secret keys to the host processor and SHALL NOT be capable of being reprogrammed by the host processor to allow the secret keys to be extracted.
