摘要: Cloud-based electronic health records (EHR) systems provide important security controls by encrypting patient data. However, these cannot be queried without decrypting the entire record. This incurs a huge amount of burden in network bandwidth and client-side computation. As volume cloud-based EHRs reaches Big Data levels, it is essential to search over encrypted them ensure that medical caregivers can efficiently access EHRs. especially critical if have only certain sections EHR should not decrypt whole In this paper, we present our novel approach facilitates searchable encryption large using Attribute-based Encryption (ABE) multi-keyword techniques. Our framework outsources key features cloud side. way, system perform keyword searches on data with significantly reduced costs
