Masked Differential-linear Distinguishers and Quantum Approaches
Shobhit Pandey, Sarbani Sen, Debajyoti Bera +1
We introduce masked auto-correlation, a new primitive for the cryptanalysis of symmetric-key primitives, together with a quantum attack pipeline built on it. For a permutation ,…

Tight Analysis of a One-Shot Quantum Secret Sharing Scheme
Santanu Majhi, Debajyoti Bera
Quantum communication protocols can be designed to detect eavesdropping attacks, something that classical technologies are unable to do since classical information can be replicate…

Quantum Query-Space Lower Bounds Using Branching Programs
Debajyoti Bera, Tharrmashastha SAPV
Branching programs are quite popular for studying time-space lower bounds. Bera et al. recently introduced the model of generalized quantum branching program aka. GQBP that general…
