| dc.description.abstract | 在現今,全同態加密在隱私保護中扮演重要的角色,像是雲端運算服務。在這項技術中,打破以往運算需要在明文的狀態下進行,而是可以再密文狀態下進行運算。這也使得隱私資料在交由第三方服務時可以得到更多的隱私保護,防止隱私資料外洩給第三方。然而,要再更提升資料的保護,金鑰的管理也非常重要。雖然使用全同態加密保護隱私資料,一旦金鑰外洩,之前所加密的資料就有很大的外洩風險。在我們的研究中,我們提出了一個新的全同態加密方案,並且做到金鑰的撤銷,以達到向前的安全性。在金鑰撤銷後,該金鑰所加密的密文不用擔心之後金鑰若是外洩是否有外洩的風險。 | zh_TW |
| dc.description.abstract | Fully Homomorphic Encryption (FHE) empowers secure computation over encrypted data, offering a crucial solution for privacy-preserving applications in cloud computing. However, the security of FHE is contingent upon robust key management practices. This paper introduces a novel FHE scheme that integrates a robust key revocation mechanism. By incorporating key revocation, our scheme ensures forward secrecy, guaranteeing that the confidentiality of previously encrypted data remains intact even if the secret key is subsequently compromised. | en_US |
