AONT-and-NTRU-based rekeying scheme for encrypted deduplication

Rekeying is a good way to protect against key exposure.Most of the existing encrypted deduplication systems are implemented based on message-locked-encryption, in which multiple users with the identical data share the same encryption key.When a user updates keys, that update must be followed by all other King Upholstered Headboard data owners, whic

Preparation of Composite Derived from Banana Peel Activated Carbon and MgFe2O4 as Magnetic Adsorbent for Methylene Blue Removal

Methylene blue (MB) is one of the dyes used often by the textile industry.Therefore, MB residual is contained in the textile industry waste.MB can irritate, leading to permanent eye and animal injuries; therefore, the textile industry waste concentration must be degraded before disposed to the environment.MB residual in textile industry waste can b

Analysis of nonlinear vibration characteristics of dual-rotor system under bearing misalignment-rub-coupling fault

In order to reveal the vibration characteristics of fault rotor systems caused by the bearing misalignment, the Bubbles expression of the rotor deflection displacement under the bearing misalignment was derived through the coordinate transformation relation.On this basis, the dynamic model of the double disk rotor system with the coupled bearing mi
