- Abstract
- Fully homomorphic encryption(FHE) was introduced by Rivest, Adleman, and Dertouzos that can homomorphically evaluate encrypted data. However, it turned out to be insecure. After then, it has been presented lots of improved, modified FHE schemes for security and efficiency. One of them, a FHE of López-Alt, Tromer, and Vaikuntanathan based on NTRU encryption scheme of Hoffstein, Pipher, and Silverman, is more efficient than the other schemes for a long time.
Bos et al. suggest the more efficient FHE scheme, which is the fastest, than López-Alt et al. They remove the DSPR assumption and modulus switching procedure. Thus, in this paper, we look into the scheme and implement its practical version and optimization. We provide experimental results and analyze them as regards efficiency compared with original one whose parameters are presented by authors.
