SIMULATION ANALYSIS OF INVERTING MARINE VERTICAL DEFLECTION USING SPACEBORNE GNSS-R INTERFEROMETRIC ALTIMETRY

Global marine vertical deflection is essential for understanding Earth's internal mass and density distribution and improving the long-term inertial navigation accuracy of underwater vehicles.Spaceborne global navigation Toddler Diaper Covers satellite system reflectometry (GNSS-R) interferometric altimetry, with its advantages of low-cost,

The security flaws of a direct anonymous attestation Fittings scheme proposed by Ge,et al.Were analyzed,and the re-sult shows that the authentication protocol of the scheme is vulnerable to reply attacks and platform masquerade attacks when being used for remote attestation.An improved direct anonymous attestation authentication scheme with the in-
