우리는 짧은 암호문을 사용하는 익명의 계층적 신원 기반 암호화(익명 HIBE) 체계를 제안합니다. 우리 작업 이전에 대부분의 익명 HIBE 방식은 수신자의 계층적 깊이에 따라 긴 암호문이 증가했습니다. 우리 체계의 암호문 크기는 계층 구조의 깊이에 의존하지 않습니다. 더욱이, 우리의 방식은 암호 해독 단계에서 암호 해독의 계산 비용이 일정하기 때문에 가장 낮은 계산 비용을 달성합니다. 무작위 오라클을 사용하지 않고도 합리적인 가정하에 보안성을 입증할 수 있습니다. 우리의 체계는 선택적 ID 보안 개념을 달성합니다.

Abstract: We propose an anonymous Hierarchical Identity-Based Encryption (anonymous HIBE) scheme with short ciphertexts. Prior to our work, most anonymous HIBE schemes have long ciphertexts increased according to the hierarchical depth of recipient. The size of the ciphertext in our scheme does not depend on the depth of the hierarchy. Moreover, our scheme achieves the lowest computational cost because during the decryption phase the computational cost of decryption is constant. The security can be proven under reasonable assumptions without using random oracles. Our scheme achieves selective-ID security notion.

Prior to our work, most anonymous HIBE schemes have long ciphertexts increased according to the hierarchical depth of recipient. The size of the ciphertext in our scheme does not depend on the depth of the hierarchy. Moreover, our scheme achieves the lowest computational cost because during the decryption phase the computational cost of decryption is constant. The security can be proven under reasonable assumptions without using random oracles. Our scheme achieves selective-ID security notion.
