Alexandra Boldyreva, Zichen Gui, Bogdan Warinschi ePrint Report Searchable encryption, or more generally, structured encryption, permits search over encrypted data. It is an important cryptographic tool for securing cloud storage. The standard security notion for structured encryption mandates that a protocol leaks nothing about the data or queries, except for some allowed leakage, defined by…

Théophile Brézot, Chloé Hébant ePrint Report State-of-the-art database implementations offer a wide range of functionalities and impressive performances while supporting highly concurrent loads. However they all rely on the server knowing the content of the database, which raises issues when sensitive information is being stored on a server that cannot be trusted. Encrypting documents before…

Debrup Chakraborty, Avishek Majumder, Subhabrata Samajder ePrint Report Searchable Symmetric Encryption (SSE) has emerged as a promising tool for facilitating efficient query processing over encrypted data stored in un-trusted cloud servers. Several techniques have been adopted to enhance the efficiency and security of SSE schemes. The query processing costs, storage costs and communication costs of…

Tjard Langhout, Huanhuan Chen, Kaitai Liang ePrint Report One distinguishable feature of file-inject attacks on searchable encryption schemes is the 100% query recovery rate, i.e., confirming the corresponding keyword for each query. The main efficiency consideration of file-injection attacks is the number of injected files. In the work of Zhang et al. (USENIX 2016), $|\log_2|K||$…

Yibo Cao, Shiyuan Xu, Xiu-Bo Chen, Gang Xu, Siu-Ming Yiu ePrint Report The extensive use of cloud storage has created an urgent need to search and share data. Public key authenticated encryption with keyword search (PAEKS) allows for the retrieval from encrypted data, while resisting the insider keyword guessing attacks (IKGAs). Most PAEKS schemes only…

Mahdieh Heidaripour, Ladan Kian, Maryam Rezapour, Mark Holcomb, Benjamin Fuller, Gagan Agrawal, Hoda Maleki ePrint Report Storage of sensitive multi-dimensional arrays must be secure and efficient in storage and processing time. Searchable encryption allows one to trade between security and efficiency. Searchable encryption design focuses on building indexes, overlooking the crucial aspect of record retrieval.…

Arnab Bag, Sikhar Patranabis, Debdeep Mukhopadhyay ePrint Report Searchable Symmetric Encryption (SSE) has opened up an attractive avenue for privacy-preserved processing of outsourced data on the untrusted cloud infrastructure. SSE aims to support efficient Boolean query processing with optimal storage and search overhead over large real databases. However, current constructions in the literature lack the…
