Beyond Object Authentication: Context-Closed Post-Quantum Authentication for the WebPKI
Anis Bkakria
Post-quantum migration increases WebPKI authentication cost, but authenticating a compressed certificate object does not by itself preserve the mutable authorization context under…
Rotation-Optimal Noncommutative Prefix Scans in Bit-Reversed Homomorphic Layouts
Anis Bkakria, Madicke-Diadji Mbodj, Mawloud Omar +1
Packed homomorphic encryption evaluates slotwise operations in parallel, but nonlocal communication is realized by cyclic rotations whose cost depends on the physical slot layout.…
A Privacy-Preserving Graph Encryption Scheme Based on Oblivious RAM
Seyni Kane, Anis Bkakria
Graph encryption schemes play a crucial role in facilitating secure queries on encrypted graphs hosted on untrusted servers. With applications spanning navigation systems, network…
A Framework for Managing Multifaceted Privacy Leakage While Optimizing Utility in Continuous LBS Interactions
Anis Bkakria, Reda Yaich
Privacy in Location-Based Services (LBS) has become a paramount concern with the ubiquity of mobile devices and the increasing integration of location data into various application…
