20130103953 | APPARATUS AND METHOD FOR ENCRYPTING HARD DISK - An apparatus and method for encrypting a hard disk are provided. The apparatus includes a program management unit, an Internet Protocol (IP) management unit, and an encryption processing unit. The program management unit causes an allowed program or process to be executed based on a result of determination as to whether the program or process to be executed in a host terminal is allowed to gain access. The IP management unit causes data to be transmitted to an allowed destination IP address based on a result of determination as to whether the destination IP address to which the host terminal attempts to transmit the data is allowed to be accessed. The encryption processing unit encrypts and decrypts all data, exchanged between the host terminal and the hard disk by applying an algorithm, selected by a user, to the data. | 04-25-2013 |
20130159725 | FPGA APPARATUS AND METHOD FOR PROTECTING BITSTREAM - An FPGA apparatus and a method for protecting bitstreams are provided. The FPGA apparatus includes: a key storage unit, which is configured to be accessed only from within the FPGA, and having stored therein the encryption/decryption key and the initial key generated by the random number generator; a setting bitstream storage unit, which is an internal non-volatile memory stored with bitstreams for setting authentication and encryption/decryption; and an authentication and encryption/decryption setting unit, which is configured to call the encryption and decryption key and the initial value stored in the key storage unit to store encrypted bitstreams and authentication codes generated as a result of performing encryption on the bitstreams stored in the setting bitstream storage unit in external non-volatile memory, and verity the integrity of the encrypted bitstreams stored in the external non-volatile memory at the time of designing of the FPGA using the encrypted bitstreams. | 06-20-2013 |
20150089646 | APPARATUS AND METHOD FOR PROTECTING COMMUNICATION PATTERN OF NETWORK TRAFFIC - An apparatus for protecting traffic trend in a network of a control system using artificial communication is provided. In accordance with an embodiment, the apparatus includes a communication terminal device installed in a network and configured to create and filter artificial communication. A communication server device determines whether to create artificial communication at a current time in the communication terminal device, requests a transmitting side-communication terminal device to create artificial communication, and requests a receiving side-communication terminal device to filter the artificial communication. | 03-26-2015 |
