Gentry's bootstrapping technique is still the only known method of obtaining fully
homomorphic encryption where the system's parameters do not depend on the complexity of …

The homomorphic proxy re-encryption scheme combines the characteristics of a
homomorphic encryption scheme and proxy re-encryption scheme. The proxy can not only …

Представлена новая симметричная компактная полностью гомоморфная криптос-хема,
основанная на использовании матричных полиномов и производящая шифрование в …

We propose a new fully homomorphic encryption (FHE) scheme. Unlike previous ones, our
FHE scheme is effective and simple enough for practical applications. Our FHE essentially …

Abstract The Boyen-Li signature scheme [Asiacrypt'16] is a major theoretical breakthrough.
Via a clever homomorphic evaluation of a pseudorandom function over their verification key …

Despite a great deal of progress in resent years, efficiency of fully homomorphic encryption
(FHE) is still a major concern. Specifically, the bootstrapping procedure is the most costly …

(57) ABSTRACT A request is received for specific information that can be determined using
data in a database on a first computer system. Either at least some of the data is encrypted …

Secure computation of a random number sequence in a cryptographic device. The
computation is secured by receiving a homomorphic ciphertext seed vector, selecting an …

Bootstrapping is a crucial subroutine of fully homomorphic encryption (FHE), where a
homomorphic encryption scheme evaluates its own decryption circuits. Homomorphic …

In this paper, we first present a new lattice-based PKE scheme on SIS, proving that it
achieves CPA-security under DBi-ISIS assumption. Compared to some lattice-based …
