patterns. However, this implies an expensive computation or communication cost of all the data on the server. Existing solutions are not efficient due to their impractical communication and computation cost. Besides, most of them do not support keyword search. In this paper, we introduce the mechanism of pricing to solve the
is thus desirable to enable the search service over encrypted cloud data for supporting effective and efficient data retrieval over a large number of data users and documents in the cloud. Existing approaches on encrypted cloud data search either focus on single keyword search or become inefficient when a large amount
Polynomial evaluation is an important tool in constructing many cryptographic protocols, such as proof of retrievability and verifiable keyword search. However, for the high degree polynomials derived from very large datasets, polynomial evaluation becomes an intractable problem, especially for resource limited
