Abstract
The invention provides a device with cryptographic function, which includes: a hardware unit, exhibiting hardware-intrinsic properties; a key generating unit, generating a private key according to the hardware-intrinsic properties, and generating a public key according to the private key, for exchanging public keys with an outside device to convert communication payload information into first encrypted information based on the received public key; and a session operational unit, establishing a session key configured to encrypt the first encrypted information into second encrypted information to be transmitted between the cryptographic device with cryptographic function and the outside device. The key generating unit further optionally generates a secret key according to the hardware-intrinsic properties for securing data at rest in the cryptographic device.
