A method for personal identity authentication utilizing a personal cryptographic device initially provides a personal cryptographic device storing a client key from a host system and a device serial number. Next, the personal cryptographic device is connected to the host system. Thereafter, unique user information is inputted via the personal cryptographic device. Then, the unique user information and the device serial number are encrypted and sent to the host system for authentication and for requesting key information. The personal cryptographic device receives and decrypts encrypted key information with the client key, and changes the client key using the key information. |
