Improved lattice enumeration algorithms by primal and dual reordering methods
IET Information Security, Volume 17, Issue 1, Page 35-45, January 2023., 2023 Abstract The security of lattice‐based cryptosystems is generally based on the hardness of the Shortest Vector Problem (SVP). The original enumeration (ENUM) algorithm solving SVP runs in exponential time due to the exhaustive search, which is used as a subroutine for the block Korkin–Zolotarev (BKZ) algorithm.

LaTLS: A Lattice‐Based TLS Proxy Protocol
Chinese Journal of Electronics, Volume 31, Issue 2, Page 313-321, March 2022., 2022 The function of the Internet proxy is to check and convert the data exchanged between client and server. In fact, the two‐party secure communication protocol with good security is turned into an unsafe multiparty protocol. At present, there are relatively few proxy protocols that can be applied in practice.

Lattice‐based hash‐and‐sign signatures using approximate trapdoor, revisited
IET Information Security, Volume 16, Issue 1, Page 41-50, January 2022., 2022 Abstract For the purpose of improving the efficiency of the cryptosystems built upon lattice trapdoors, Chen, Genise and Mukherjee at ASIACRYPT 2019 modified the gadget trapdoor (G‐trapdoor) to an approximate trapdoor, which enables one to sample short preimages approximately from a discrete Gaussian distribution.

A New Attack on NTRU Public Key Cryptosystem Depend on Using Public Key and Public Information [PDF]
Engineering and Technology Journal, 2010 This paper proposed a new method to attack the NTRU cryptosystem [Hof00a,Hof98b]. It tried to exploit the public information about the parameters of NTRUcryptosystem and using the public key, to recover the private keys without delvingin the detail of ...
