چکیده انگلیسی:
The notion of outsourced database allows the data owner to outsource a database to the cloud service
provider (CSP), and then anyone can enjoy database services provided by the CSP. Some new security
and privacy concerns, e.g., query integrity, are inevitably raised because of losing physical control of data.
Recently, some researchers present a verifiable data integrity auditing protocol for outsourced database,
which satisfies both the correctness and completeness of search result even if the CSP intentionally returns
an empty set. However, for each attribute column, the data owner needs to count the number of data
tuples with the same value in advance. Any slight update operation may bring about huge computation
and communication overhead. This makes it very hard to be applicable to dynamic outsourced database
scenario. To address the above challenge, we propose a novel verifiable search scheme for outsourced
database based on invertible Bloom filter (IBF), which can achieve verifiability of search result without
the process of pre-counting. Furthermore, the proposed scheme is extended to multi-user setting by
incorporating multi-party searchable encryption (MPSE), which can resist collusion attack between
the CSP and any malicious users. Finally, security and efficiency evaluation show that the proposed
construction can achieve the desired security properties, while providing a comparable computation and
storage overhead.
