Searchable Encryption(SE) schemes allow users to perform keyword search on encrypted data without leakage of the sensitive information. Most of the existing SE schemes are limited to single-user setting or multi-user setting with coarser-grained access control. However, the application that multiple users with different access rights to the sharing data is(More)
Searchable encryption(SE) schemes allow users to perform keyword search on encrypted data without leakage of the sensitive information. Most of the existing SE schemes are limited to single-user setting where a user acts as both the data owner and the data retriever. However, the data-sharing environment drives multiple users to access the same data sets.(More)
As to solve the shortcomings such as waste of resources, high cost of support, low support efficiency as a result of the over-stocked materiel and under-stocked materiel existing in equipment maintenance materiel storage support, the coordinative allocation was put forward to alleviate the problem of imbalanced resource storage, in which the over-stocked(More)
In video encoding, there are seven block sizes used for inter-frame motion estimation/compensation for H.264.However, this feature requires the encoder to compute the rate-distortion cost for every available block mode. As a result, the complexity and computation load of video coding increase drastically. In this paper, a new fast inter mode decision method(More)
