Abstract: PURPOSE: A hard disk encoding device and a method thereof are provided to determine various kinds of hard disk access possibilities and to perform encryption and decryption, thereby safely protecting user data in a hard disk when it is stolen. CONSTITUTION: A program management unit(160) executes an accessible program and a process corresponding to a determined result of access approval. An IP management unit(170) transmits data to an accessible destination IP address corresponding to the determined result of the access approval for the destination IP address. A password processing unit(130) performs encryption and decryption by applying an algorithm to all data which is transmitted and received between a host terminal and a hard disk. A host matching unit(120) is operated by selectively connecting an interface in the hard disk to the host terminal.

Abstract: An illegal transmitter detector and a method thereof are provided to prevent information leakage by always detecting whether an illegal transmitter, such as a wiretapping device, and a concealed video camera, is installed at a desired place. An illegal transmitter detector comprises an antenna(100), an RF receiving part(200), an ADC part(300), an unauthorized signal processing part(400), and a warning display part(500). The antenna receives a radio signal transmitted from an illegal transmitter. The RF receiving part detects a signal of a specific frequency band, which is set to detect the illegal transmitter, among the radio signal received at the antenna. The ADC part converts the detected signal into a digital signal. The unauthorized signal processing part controls the RF receiving part and the ADC part. The unauthorized signal processing part compares the converted digital signal with signal information in a frequency information table and judges whether the digital signal is an unauthorized signal. In case it is judged that the digital signal is an unauthorized signal, the unauthorized signal processing part outputs a warning signal. The warning display part, if the warning signal is inputted from the unauthorized signal processing part, executes warning display for the appearance of the unauthorized signal.

Abstract: An apparatus and a method for processing multi session high-speed encryption and decryption are provided to reduce processing delay and load generated when generating an encryption and decryption key through key exchange at every session, by improving an encryption and decryption processing speed. A key sharing processing part(130) performs load dispersion of encryption devices of a parallel encryption apparatus(150) by generating an encryption key value and reading a header when every session is received. A header conversion part(120) converts an ID designating a corresponding encryption device for processing and key position information related with an encryption key, as to the header of the session. The parallel encryption apparatus comprises N encryption devices to perform encryption of a payload as to a session inputted by being dispersed, using the ID, the key position information and the encryption key.
