IBE(신원 기반 암호화)에 대한 주요 논문에서 Boneh와 Franklin[6]은 Moni Naor가 관찰한 IBE 체계에서 서명 체계로의 흥미로운 변환을 언급했습니다. 이 문서에서는 이 변환에 대한 공식적인 보안 처리 방법을 제공하고 IBE와 변환된 서명의 보안 개념 간의 여러 의미와 구분을 발견합니다. 예를 들어, 성공적인 변환을 위해서는 IBE의 단방향성이 필수 조건이라는 것을 보여줍니다. 또한 의미론적으로 안전한 IBE 체계를 실존적으로 위조할 수 없는 서명 체계로 변환하기 위한 충분하고 필요한 조건을 제공합니다. 우리의 결과는 (아마도 취약한) IBE 체계에서 서명 체계의 설계 및 자동 보안 증명에 대한 전략을 수립하는 데 도움이 됩니다. 또한 IBE의 의미론적 보안보다는 단방향성이 보안 서명을 달성하기 위한 필수 조건을 포착한다는 것을 강력하게 뒷받침하는 몇 가지 분리 결과를 보여줍니다.

Abstract: In a seminal paper of identity based encryption (IBE), Boneh and Franklin [6] mentioned an interesting transform from an IBE scheme to a signature scheme, which was observed by Moni Naor. In this paper, we give formal security treatments for this transform and discover several implications and separations among security notions of IBE and transformed signature. For example, we show for such a successful transform, one-wayness of IBE is an essential condition. Additionally, we give a sufficient and necessary condition for converting a semantically secure IBE scheme into an existentially unforgeable signature scheme. Our results help establish strategies on design and automatic security proof of signature schemes from (possibly weak) IBE schemes. We also show some separation results which strongly support that one-wayness, rather than semantic security, of IBE captures an essential condition to achieve secure signature.
