The NTRU lattice is a promising candidate to construct practical cryptosystems, in particular
key encapsulation mechanism (KEM), resistant to quantum computing attacks. Nevertheless …

We present BAT–an IND-CCA secure key encapsulation mechanism (KEM) that is based on
NTRU but follows an encryption/decryption paradigm distinct from classical NTRU KEMs. It …

Lattice-based cryptosystems are some of the primary post-quantum secure alternatives to
the asymmetric cryptography that is used today. These lattice-based cryptosystems typically …

Recently, NIST has announced Kyber, a lattice-based key encapsulation mechanism (KEM),
as a post-quantum standard. However, it is not the most efficient scheme among the NIST's …

Several ideal-lattice-based cryptosystems have been broken by recent attacks that exploit
special structures of the rings used in those cryptosystems. The same structures are also …

In this paper, we propose NTRU-LPR IND-CPA, a new secure scheme based on the
decisional variant of Bounded Distance Decoding problem over rings (DR-BDD). This …

The emergence of practical quantum computers will threaten the classical computers, which
makes the resistant quantum cryptography become so important and urgent, where lattice …

As an invited speaker of the ACISP 2017 conference, Dongxi Liu recently introduced a new
lattice-based encryption scheme (joint work with Li, Kim and Nepal) designed for lightweight …

Lattice-based cryptography is one of the most promising schemes for post-quantum
cryptography. Among the many lattice-based cryptosystems, FrodoKEM is a well-known key …

It is still a challenge to find a lattice-based public-key encryption scheme that combines
efficiency (as eg NTRUEncrypt) with a very strong security guarantee (as eg the ring-LWE …
