A Novel Approximation Algorithm for the Shortest Vector Problem
Finding the shortest vector in a lattice is a NP-hard problem. The best known approximation algorithm for this problem is LLL algorithm with the approximation factor of $\alpha ^{\frac {n-1}{2}}$ , $\alpha \geq \frac {4}{3}$ , which is not a good ...

Sieve algorithms for the shortest vector problem are practical [PDF]
The most famous lattice problem is the Shortest Vector Problem (SVP), which has many applications in cryptology. The best approximation algorithms known for SVP in high dimension rely on a subroutine for exact SVP in low dimension.

Improved hardness results for unique shortest vector problem [PDF]
We give several improvements on the known hardness of the unique shortest vector problem. - We give a deterministic reduction from the shortest vector problem to the unique shortest vector problem. As a byproduct, we get deterministic NP-hardness for unique shortest vector problem in the $\ell_\infty$ norm.

Explicit Hard Instances of the Shortest Vector Problem [PDF]
Building upon a famous result due to Ajtai, we propose a sequence of lattice bases with growing dimension, which can be expected to be hard instances of the shortest vector problem ( SVP ) and which can therefore be used to benchmark lattice reduction algorithms. The SVP is the basis of security for potentially post-quantum cryptosystems.

On the Ideal Shortest Vector Problem over Random Rational Primes [PDF]
Any ideal in a number field can be factored into a product of prime ideals. In this paper we study the prime ideal shortest vector problem (SVP) in the ring $ \Z[x]/(x^{2^n} + 1) $, a popular choice in the design of ideal lattice based cryptosystems. We show that a majority of rational primes lie under prime ideals admitting a polynomial time algorithm

The nc-Unique Shortest Vector Problem is Hard. [PDF]
The unique Shortest Vector Problem (uSVP) gained prominence because it was the problem upon which the first provably-secure lattice-based cryptosystems were built.

Heuristic Time Complexity of NISQ Shortest-Vector-Problem Solvers
The shortest vector problem (SVP) is central to the security of lattice-based cryptography, forming the foundation of two of the three NIST-standardized postquantum cryptosystems. Understanding how quantum algorithms perform on SVP is vital for assessing

On the hardness of the shortest vector problem. [PDF]
An n-dimensional lattice is the set of all integral linear combinations of n linearly independent vectors in Rm. One of the most studied algorithmic problems on lattices is the shortest vector problem (SVP): given a lattice, find the shortest non-zero vector in it.

Techniques for Solving Shortest Vector Problem [PDF]
Lattice-based crypto systems are regarded as secure and believed to be secure even against quantum computers. lattice-based cryptography relies upon problems like the Shortest Vector Problem. Shortest Vector Problem is an instance of lattice problems that are used as a basis for secure cryptographic schemes.
