Abstract: PURPOSE: A system for processing a DES(Data Encryption Standard) in parallel by using a graphic processing unit is provided to improve a processing speed by performing a high speed parallel process of a DES based on the resources of a graphic processor. CONSTITUTION: A round key generator(303) generates 16 round keys for a DES(Data Encryption Standard) from 56-bit key. A main unit(302) stores the round keys and an Sbox(Secret box) at a first memory of a graphic processor. In addition, the main unit stores the 64-bit data strings at a second memory of the graphic processor. Furthermore, the main unit processes the stored 64-bit data strings in parallel simultaneously by using the round keys and the Sbox which are stored in the first memory.

Abstract: PURPOSE: An apparatus and a method for providing a reliable channel in a security OS(Operating System) to which MAC(Mandatory Access Control) is applied is provided to offer a new header for independently encoding a packet used in communication by a security level of the MAC and minimize network performance degradation using the security level of the MAC. CONSTITUTION: If data according to a communication request provided from a transmission-side user(S1) are for a packet transmission request, a reliable channel subsystem(12) judges whether a reliable channel is applied. If the reliable channel is applied, the reliable channel subsystem(12) composes a reliable channel header, encodes a specific portion of a packet, stores authentication information in the reliable channel header, and transmits the packet through a network(A). A MAC module(20) provides MAC information for indicating whether the reliable channel is applied. A kernel memory(30) provides an encryption key and an authentication key necessary for encoding a reliable channel application host address and the packet and generating authentication data. A reliable channel subsystem(12-1) retrieves the authentication data of the reliable channel header before decoding the packet received through the network(A). If the authentication data are valid, the reliable channel subsystem(12-1) decodes the encoded packet. If process for the reliable channel is ended, the reliable channel subsystem(12-1) transmits the packet to an upper level to transmit the packet to a reception-side user(S2). A kernel memory provides an authentication key and an encryption key necessary for checking authentication with respect to the packet encoded by the reliable channel subsystem(12) and decoding the packet.
