Fully Homomorphic Encryption without bootstrapping
Gentry’s bootstrapping technique is the most famous method of obtaining fully homomorphic encryption. In previous work I proposed a fully homomorphic encryption without bootstrapping which has the weak point in the plaintext [1]. In this paper I propose the improved fully homomorphic encryption scheme on non-associative octonion ring over finite field without bootstrapping technique where the p...
متن کاملFully Homomorphic Encryption without Bootstrapping
We present a radically new approach to fully homomorphic encryption (FHE) that dramatically improves performance and bases security on weaker assumptions. A central conceptual contribution in our work is a new way of constructing leveled fully homomorphic encryption schemes (capable of evaluating arbitrary polynomial-size circuits), without Gentry’s bootstrapping procedure. Specifically, we off...

Gentry’s bootstrapping technique is the most famous method of obtaining fully homomorphic encryption. In previous work I proposed a fully homomorphic encryption without bootstrapping which has the weak point in the enciphering function. In this paper I propose the improved fully homomorphic public-key encryption scheme on non-associative octonion ring over finite field without bootstrapping tec...
متن کاملNotes on Two Fully Homomorphic Encryption Schemes Without Bootstrapping
Recently, IACR ePrint archive posted two fully homomorphic encryption schemes without bootstrapping. In this note, we show that these schemes are trivially insecure. Furthermore, we also show that the encryption schemes of Liu and Wang [6] in CCS 2012 and the encryption scheme of Liu, Bertino, and Xun [5] in ASIACCS 2014 are insecure either.
متن کاملBetter Bootstrapping in Fully Homomorphic Encryption
Gentry’s bootstrapping technique is currently the only known method of obtaining a “pure” fully homomorphic encryption (FHE) schemes, and it may offers performance advantages even in cases that do not require pure FHE (such as when using the new noise-control technique of Brakerski-GentryVaikuntanathan). The main bottleneck in bootstrapping is the need to evaluate homomorphically the reduction ...
