Abstract:
PURPOSE: An aria encryption apparatus and a method thereof are provided to efficiently use an aria encryption algorithm by calculating the output of a masking S-box. CONSTITUTION: A controller(110) entirely controls the drive of aria encryption devices(100). The controller generates a masked random number. A round key generating section(120) generates a round key by using an inputted cryptographic key. A masking section(130) generates masked input data by using inputted data and the masked random number generated in the controller. An erasable programmable read-only memory(140) stores a table used for calculating the output of a S-box. An operational sequence generating unit(150) randomly generates an operational sequence for executing key addition. A key edition section(160) calculates an input value masked based on a generated operational sequence and a masked round key value. A S-box operation section(170) calculates the output of the S-box.

본 발명은 스마트카드 판독장치의 인증시스템 및 그 방법에 관한 것으로, 스마트카드 수록정보를 판독하기 전에 온라인 상의 인증장치가 판독장치를 인증하여 판독소프트웨어 및 리더기의 정당성을 확보하고, 스마트카드가 외부환경의 정당성을 인증하는 과정과 연계하여 스마트카드에 대한 접근제어를 가능하게 함으로써 스마트카드 수록정보의 불법 유출을 시도하는 해커의 판독소프트웨어 및 리더기에 대한 위,변조 위협을 차단할 수 있도록 하는 스마트카드 판독장치의 인증시스템 및 그 방법을 제공함에 그 목적이 있다.
Abstract:
PURPOSE: A combi card system using a combi card and a combi card communication device with radio frequency antennas are provided to switch a specific RF antenna during a fixed period, thereby efficiently exchanging data by minimum power consumption. CONSTITUTION: A combi card(1000) comprises a transponder chip module. A transponder chip module includes an IC chip, the first RF(Radio Frequency) antenna supporting a non-contact interface and an electric connecting pin supporting a contact interface. A combi card communication device with RF antennas includes a card reader(400). The card reader includes the second RF antenna(410) and an antenna controller(430).
Abstract:
The present invention relates to a system and a method for authenticating a smartcard reading device. According to the system and the method for authenticating a smartcard reading device, an authentication device authenticates a reading device prior to reading smartcard-contained information to secure justice of reading software and the reading device and enables control to access to the smartcard by interworking with a process of authenticating justice of an external environment in the smartcard, thereby block a forgery and alteration intimate of a hacker attempting to illegal drain of the smartcard-contained information, with respect to the reading software and the reading device.
