Side-channel analysis of a learning parity with physical noise processor

Journal of Cryptographic Engineering, 2020
Learning parity with physical noise (LPPN) has been proposed as an assumption on which to build authentication protocols based on the learning parity with noise (LPN) problem. Its first advantage is to reduce the randomness requirements of standard LPN-based protocols, by directly performing erroneous computations so that no (e.g. Bernoulli-distributed)

Probing the Planck Scale with Proton Decay [PDF]

, 2004
We advocate the idea that proton decay may probe physics at the Planck scale instead of the GUT scale. This is possible because supersymmetric theories have dimension-5 operators that can induce proton decay at dangerous rates, even with R-parity ...

Reevaluation of the role of nuclear uncertainties in experiments on atomic parity violation with isotopic chains [PDF]

, 2001
In light of new data on neutron distributions from experiments with antiprotonic atoms [ Trzcinska {\it et al.}, Phys. Rev. Lett. 87, 082501 (2001)], we reexamine the role of nuclear-structure uncertainties in the interpretation of measurements of parity
