| Abstract | Disclosed are an encryption method and apparatus for supporting an equivalent query for ciphertexts in a multi-client environment. According to one embodiment of the present invention, the method comprises the steps of: obtaining a user encryption key from a key generating device; and generating a ciphertext for an attribute vector based on a label for the attribute vector and the user encryption key.
멀티 클라이언트 환경에서 암호문들에 대한 동치 질의를 지원하는 암호화 방법 및 장치가 개시된다. 일 실시예에 따른 방법은, 키 생성 장치로부터 사용자 암호키를 획득하는 단계 및 속성 벡터에 대한 라벨(label) 및 상기 사용자 암호키에 기초하여 상기 속성 벡터에 대한 암호문을 생성하는 단계를 포함한다. |
