Worst--Case to Average--Case Reductions for SIS over integers
Konstantinos A. Draziotis, Myrto Eleftheria Gkogkou
In the present paper we study a non-modular variant of the Short Integer Solution problem over the integers. Given a random matrix with entries $a_{i…

Message Recovery Attack in NTRU via Knapsack
Eirini Poimenidou, K. A. Draziotis
In the present paper, we introduce a message-recovery attack based on the Modular Knapsack Problem, applicable to all variants of the NTRU-HPS cryptosystem. Assuming that a fractio…

Message Recovery Attack in NTRU through VFK Lattices
Eirini Poimenidou, Marios Adamoudis, Konstantinos A. Draziotis +1
In the present paper, we implement a message recovery attack to all variants of the NTRU cryptosystem. Our approach involves a reduction from the NTRU-lattice to a Voronoi First Ki…
