However, most existing searchable encryption schemes are vulnerable to keyword guessing attacks. During keyword guessing attacks, with the help of the cloud, an adversary will learn what keyword a given trapdoor is searching for, which leads to the disclosure of users’ privacy information. To address this issue, we propose SDKSE-KGA: a secure dynamic keyword searchable encryption scheme which resists keyword guessing attacks. SDKSE-KGA has constant-size indexes and trapdoors and supports functionalities such as dynamic updating of keywords and files. Formal proofs show that it is Trapdoor-IND-CKA and Index-IND-CKA secure in the standard model. %G English %Z TC 11 %Z WG 11.11 %2 https://inria.hal.science/hal-03182606/document %2 https://inria.hal.science/hal-03182606/file/491176_1_En_13_Chapter.pdf %L hal-03182606 %U https://inria.hal.science/hal-03182606 %~ IFIP %~ IFIP-AICT %~ IFIP-TC %~ IFIP-TC11 %~ IFIP-TM %~ IFIP-WG11-11 %~ IFIP-AICT-563
