Abstract:
A cryptographic system includes a host device and a cryptographic device. For encryption, the host includes an application that is configured to enable a user to compose an unencrypted message on a user interface and transmit the unencrypted message. The cryptographic device is configured to receive the unencrypted message, encrypt the unencrypted message with RCPs on a non-volatile storage to create an encrypted message, and send the encrypted message to the host, which then transmits the encrypted message through a communication channel. For decryption, the host receives an encrypted message through the communication channel and sends it to the cryptographic device. The cryptographic device decrypts the encrypted message with the RCPs and sends the decrypted message back to the host, which presents the decrypted message on a display. The cryptographic device may be configured to destroy RCPs that have been used up.
