Simulation-Based Selective Opening Security for Receivers under Chosen-Ciphertext Attacks
simulation-based security selective opening security for receivers chosen-ciphertext attacks
2018/8/21
Security against selective opening attack (SOA) for receivers requires that in a multi-user setting, even if an adversary has access to all ciphertexts, and adaptively corrupts some fraction of the us...

Time Synchronization GPS Common-View GPS
2018/5/16
In recent years, with the development of satellite orbit and clock parameters accurately determining technology and the popularity of geodetic GPS receivers, Common-View (CV) which proposed in 1980 by...
Selective Opening Security for Receivers
Selective Opening Attacks Encryption Schemes Non-Committing Encryption
2015/12/23
In a selective opening (SO) attack an adversary breaks into a subset of honestly created ciphertexts

REDUCTION OF GPS STANDARD RECEIVERS NOISE USING PARALLEL-STRUCTURE WAVELET BASED NEURAL NETWORKS
Reduction Noise GPS Parallel-Structure Wavelet Neural Networks
2015/8/10
Position information obtained from standard GPS receivers is known to be corrupted with noise. To make effective use of GPS information in a navigation system it is essential to model this noise and t...
Narrowband receivers are more robust to narrowband interference and to GPS signal faults, but they tend to have relatively poor multipath performance. Few current techniques are capable of mitigating ...
Most high performance GPS receivers today are wideband. In most cases, they require the wider precorrelation bandwidth for enhanced multipath mitigation capability. Wideband receivers, however, are st...
