Yujiao Yuan, Baocheng Wang, Han Zhang · 2025
This scheme utilizes cloud computing technology and searchable encryption as well as collaborative edge computing, and proposes Verifiable Dynamic Ciphertext Searchable Encryption Scheme with Cloud Edge Assistance (VDSECEA), which solves the following problems in secure and efficient data search service scenarios: (1) For edge devices with limited storage capacity and computing power, an intelligent edge computing center is introduced to complete operations with high computational complexity and improve the computing efficiency of the client; (2) Ensure the integrity and correctness of searchable results in ciphertext implementation. Compared with existing solutions, we have achieved higher efficiency and security in index construction, trapdoor generation, and index updates for lightweight clients.
