Cryptographic USB Token Security:

Digital signatures are legally required to be stored inside a FIPS 140-2 Level 2 certified hardware cryptographic token (such as ePass2003, ProxKey, or mToken). The cryptographic private key never leaves the secure microchip of the token, preventing unauthorized copying, remote cloning, or cyber tampering.
