According to the improvemnent of electronic commerce, the requirements of security devices are becoming increasingly pervasive. The security API must design easily and securely to support a compatibility feature between security devices. It is chosen the PKCS #11 interface by RSA Labs that shows the compatibility and extensibility standards of many application product and implementation, and supported KCDSA mechanism which is a korean digital signature standard. And the PKCS #11 security API defines new key management function which provides more secure key management ability. We suggest the object attributes and templates of KCDSA private and public key object, generate and verify digital signature using KCDSA mechanism. The PKCS #11 supporting KCDSA mechanism is designed, implemented using C-Language, tested a performance, and analyzed the security and compatibiltiy feature.

다양한 개발 환경과 분산 응용 서비스에 적용할 수 있는 보안 API 기술의 필요성이 대두되고 있다. 암호토큰 호환성을 지원하는 RSA의 Cryptoki 모델을 선택하여, PKCS#11에 기반한 국내 전자서명 표준인 KCDSA 알고리즘과 HAS-160에 대한 메커니즘을 설계한다. 설계한 KCDSA 메커니즘을 PKCS#11에 추가하여 기능을 향상시키므로써, 국내전자상거래에 호환성과 효율성을 제공하는 효과를 기대할 수 있다.

As the wireless communication technology developed, the Electric Commerce using a mobile was activated. WPKI was developed in order to guarantee the stability of the Electric Commerce but it is difficult to be ensured for the safe PKI service which is the same at the wire communication in the technical because of restriction of the mobile terminal. In this paper, we propose the authentication system for the electronic financial service which is safe and is effective in consideration of the restrictive characteristic of the mobile terminal. Moreover, the encryption algorithm for the safe electronic signature is proposed. In WPKI, this makes the cross certification of each certificate authority possible. Moreover, a stability was enhanced through the signature authentication using KCDSA and SEED algorithm.
