For proper communication with various types of IC-Card, multiple IC-Card interface complying with the IC-Card standard (ISO7816) is embedded and realized as a peripheral on the 32-bit RISC based system-on-a-chip. It provides the generation of either 3.3V or 5V power supply for the operation of the inserted IC-Card as well. IC-Card interface is divided into an analog front-end (AFE) and a digital back-end (DBE). The embedded DC-DC converters suitable for driving IC-Cards are incorporated in the AFE. The chip design for multiple IC-Card interface is implemented on a standard 0.35${\mu}{\textrm}{m}$ triple-metal double-poly CMOS process and is packaged in a 352-pin plastic ball grid array (PBGA). The total gate count is about 400,000, excluding the internal memory. Die area is 7890${\mu}{\textrm}{m}$ $\times$ 7890${\mu}{\textrm}{m}$.

IC 카드의 하드웨어적인 제약으로 대부분의 IC 카드는 대칭키 알고리즘을 사용하고 있지만 IC 카드 하드웨어 제조 기술의 발전으로 앞으로는 보안성이 우수한 비대 칭키 알고리즘이 많이 사용될 것이다. 그리고 IC 카드의 가장 큰 제약적 중 하나는 메모리 용량의 한계이다. 따라서 보안상 안전하면서도 메모리를 적게 사용하는 IC 카드 운영체제의 구현을 중요한 문제이다. 그래서 본 논문에서는 다양한 종류의 키 알고리즘을 수용할 수 있는 키 파일 탐색 기법을 제안하였다. 또한 데이터 파일 헤더에 잠금 필드를 삽입하여 보안성을 향상시켰으며 메모리 사용량을 줄일 수 있도록 데이터 파일 헤더만을 이용한 파일 탐색 기법과 자유 공간 탐색 기법을 제안하였다. Because of the evolution of IC card hardware fabrication technologies IC card will be able to accept asymmetric key encryption algorithm in the future. One of the most restrictive points of IC card is memory capacity. Therefore it is an important problem to design a secure IC card operating system using memory in small. In this paper we proposed a key file search mechanism using a key length field inserted in a key file header structure. The key file search mechanism makes IC card execute any key-based encryption algorithm. In addition we proposed inserting a lock field in data file header structure. The lock field intensifies the security of a data file. Finally we proposed a data file search mechanism and free space search mechanism using only data file header. The file system using these mechanisms spends smaller memory than that using a file description table and record of unallocated space.

The demands of IC card payment system has been increased according to the rapid advancement of the IT convergence application technologies. Recently IC card payment systems are in demands of the usage space at anytime and anywhere by developing the wireless communication technology and its related multimedia processing technology. Therefore the security of IC card payment system becomes more important and necessary. There are many fault analysis methods to evaluate the security and safety of information systems according to their characteristics and usages. However, the only assessment method to evaluate the security of information systems is not enough to analyse properly on account of the various types and characteristics of information systems by the progress of IT convergence and their applications. Therefore, this paper proposes an integrative method of the Fault Tree Analysis (FTA) and Fault Modes and Effect Analysis/Criticality (FMEA/C) based on criticality to evaluate and improve the security of IC card payment system as an illustration.

In recent, the contactless IC card is widely used in traffic, access control system and so forth. Contactless smart cards use a technology that enables card readers to provide power for transactions and communications without making physical contact with the cards. Usually electromagnetic signal is used for communication between the card and the reader. Contactless card is highly suitable for large quantity of card access and data transaction. And its use becomes a general tendency more and more because of the development of RF technology and improvement of requirement for user convenience. This paper describes the hardware module to process contactless protocol for implementation contactless IC card. And the hardware module consists of specific digital logic circuits that analyze digital signal from analog circuit and then generate data & status signal for CPU, and that convert the data from CPU into digital signal for analog circuit.
