CHAMP: Cayley HAshing with Matrix Products
Alexander Demin, Alexey Ovchinnikov, Vladimir Shpilrain
Cayley hash functions hash binary strings by representing the bits of the message as elements of a semigroup and multiplying the corresponding elements. This gives Cayley hash func…
Practical Algebraic Parameter Estimation for Noisy Data via Gaussian Process Regression
Oren Bassik, Alexander Demin, Alexey Ovchinnikov
Parameter estimation for ordinary differential equation (ODE) models is a fundamental task that is often complicated by the limitations of conventional optimization-based methods.…
Redactable blockchains and polynomial equations
Alexander Demin, Alexey Ovchinnikov, Vladimir Shpilrain
We develop new tools for constructing redactable authenticated data structures with post-quantum security. In our construction, inverting the proposed one-way function means solvin…
