Subgroup Packing for Batched PASTA Transciphering
Mugurel Barcau, Vicenţiu Paşol, George C. Ţurcaş
With transciphering, a server converts symmetrically encrypted records into homomorphic ciphertexts without learning the records or the symmetric key. For the PASTA cipher, this co…
On the second moment and non-vanishing of central values of Hecke -functions of -th order characters
Adrian Diaconu, Bogdan Ion, Vicenţiu Paşol +1
In this paper, we establish asymptotic formulas for the first and second twisted moments of -th order Hecke -functions over global fields that contain the -th roots of un…
Transversal Difference Numbers in Finite Abelian Quotients
Mugurel Barcau, Vicenţiu Paşol, George C. Ţurcaş
Given \(H\leq G\) finite abelian groups, a transversal \(T\subseteq G\) for \(G/H\) has fixed size \(|G/H|\), but its ambient difference support \(D(T)=T-T\) can vary with the embe…
Bridges connecting Encryption Schemes
Mugurel Barcau, Cristian Lupascu, Vicentiu Pasol +1
The present work investigates a type of morphisms between encryption schemes, called bridges. By associating an encryption scheme to every such bridge, we define and examine their…
Logarithmic Density of Rank and Rank Genus-2 Jacobians and Applications to Hyperelliptic Curve Cryptography
Razvan Barbulescu, Mugurel Barcau, Vicentiu Pasol +1
In this work we study quantitative existence results for genus- curves over whose Jacobians have Mordell--Weil rank at least or , ordering the curves by the…
Composing Bridges
Mugurel Barcau, Vicenţiu Paşol, George C. Ţurcaş
The present work builds on previous investigations of the authors (and their collaborators) regarding bridges, a certain type of morphisms between encryption schemes, making a step…
