프록시 재암호화 시스템에 대한 세분화된 위임을 활성화하기 위해 AsiaCCS'09에서 Weng 등은 조건부 프록시 재암호화(C-PRE) 개념을 도입했습니다. 이 개념에서는 프록시가 다음과 같은 경우에만 암호문을 변환할 수 있습니다. 지정된 조건이 만족됩니다. Wenget al. 또한 C-PRE 체계를 제안했으며 그들의 체계가 선택 암호문 공격(CCA)으로부터 안전하다고 주장했습니다. 이 문서에서는 정의된 보안 모델에 따라 해당 체계가 CCA 보안이 아님을 보여줍니다.

Abstract: To enable fine-grained delegations for proxy re-encryption systems, in AsiaCCS'09, Weng et al.'s introduced the concept of conditional proxy re-encryption (C-PRE), in which the proxy can convert a ciphertext only if a specified condition is satisfied. Weng et al. also proposed a C-PRE scheme, and claimed that their scheme is secure against chosen-ciphertext attack (CCA). In this paper, we show that their scheme is not CCA-secure under their defined security model.
