Abstract: “Cloud storage services have grown extensively in recent years. For privacy and security purposes, outsourced data must be encrypted. Therefore, searching the encrypted cloud-stored data is a big challenge. Although there are plenty of searchable encryption schemes, most rely on keywords located in the encrypted data instead of more complex searching criteria. Moreover, they do not consider the malicious coercer issue. In this paper, we propose a searchable encryption scheme that supports expressive keyword-matching conditions and provides deniable searchability to the user.“
