Homomorphic Lower Digits Removal and Improved FHE Bootstrapping
Bootstrapping is a crucial operation in Gentry’s breakthrough work on fully homomorphic encryption (FHE), where a homomorphic encryption scheme evaluates its own decryption algorithm. There has been a couple of implementations of bootstrapping, among which…

Spectral and Wavelet Coherence for Point Processes: A Tool for Cyber
Computer networks can be represented by (marked) point processes communicating information between nodes. Developing methodologies for finding and understanding correlations that exist between the point processes, particularly methods that can deal with inherent non-stationarity in…
