The performance of a cryptographic module is the most important thing to achieve a high performance VPN system which realizes information security by encrypting and decrypting all the communicating data packets. However the cryptographic operations require much computation power and software cryptographic systems reveal bad performance. Thus, it is strongly recommended to develop a VPN system employing hardware component. This paper introduces a case study of developing a PCI add-on card which supports several block cipher algorithms such as DES, 3DES, AES, and SEED. The performance of them was measured by embedding the card in a commercial VPN system.

Implementing a hardware cryptographic system is strongly required to assure high Qualify contents security. Not only because the many of the prevalent cryptographic algorithms require much computation time but also software implementations of cryptographic systems do not guarantee high performance, we need to design a hardware cryptographic system with a dedicated crypto-chip. This paper describes a case study of implementing a PCI cryptographic card which supports cryptographic algorithms such as 3DES, AES, SEED.

전자상거래의 트래픽이 엄청나게 증가하고 많은 사용자들이 안전한 온라인 거래를 요구함에 따라 고속 암호연산 프로세서의 필요성은 증대되고 있다. 고속 암호연산 프로세서란 복잡한 연산이 많은 암호방식의 연산 속도를 가속시키기 위한 보조프로세서이다. 본 고에서는 암호 사업분야 중 고속 암호연산 프로세서의 필요성을 알아보고 국내·외제품들을 분류한 뒤 프로세서들의 기능, 성능비교 및 안전성을 위주로 조사·분석하였다. 또한 고속 암호연산 프로세서의 전망 및 발전방향을 알아보고 프로세서가 사용되는 SSL가속기, IPSec가속기, HSM, 스마트카드 제품들의 성능을 위주로 소개하기로 한다.
