Abstract :
[en] A key recovery attack allows an attacker to recover the pri- vate key of an underlying encryption scheme when given a number of decryption oracle accesses. Previous research has shown that most exist- ing Somewhat Homomorphic Encryption (SHE) schemes su er from this attack. In this paper, we propose e cient key recovery attacks against two NTRU-based SHE schemes due to Lopez-Alt et al. (2012) and Bos et al. (2013), which have not gained much attention in the literature. Paral- lel to our work, Dahab, Galbraith and Morais (2015) have also proposed similar attacks but only for speci c parameter settings. In comparison, our attacks apply to all parameter settings and are more e cient.
