개인정보암호화에 효율적인 새로운 형태보존암호화 알고리즘

국문 초록 (Abstract)

최근 금융기관 및 대형 유통업체 등에서 대량의 개인정보유출사고가 연이어 발생하고, 그 피해는 날로 늘어나는 추세에 있다. 이에 따라 개인식별정보를 암호화하도록 강제하는 등 규제가 강화되고 있다. 이러한 개인정보를 암호화하는데 있어서 효율적인 기술이 형태보존암호화이다. 일반적인 암호화방식은 입력 데이터 길이보다 출력 데이터 길이가 확장되며 형태가 변경된다. 형태보존암호화는 입력 데이터의 길이와 형태를 보존해주기 때문에 데이터베이스 및 응용프로그램 수정을 최소화하는 효율적인 방식이다. 본 논문에서는 블록암호 운영모드를 이용한 개인정보 암호화에 효율적인 형태보존암호화방식을 새롭게 제안한다.

Recently financial institutions and large retailers have a large amount of personal information leakage accident occurred one after another, and the damage is a trend of increasing day by day. Regulation such as enforcing the encryption of the personal identification information are strengthened. Efficient technology to encrypt personal information is Format-preserving encryption. Typical encryption expand output data length than input data length and change a format. Format Preserving Encryption is an efficient method to minimize database and application modification, because it makes preserve length and format of input data. In this paper, to encrypt personal information efficiently, we propose newly Format Preserving Encryption using Block cipher mode of operation.
