Lattice-based cryptography

2017 12th International Conference on Computer Engineering and Systems (ICCES), 2017
Among the different cryptosystems, the Public Key Cryptosystems (PKCS) are of great usage and are used in many applications. Most of the current PKCS are based on a hard problem making the cryptanalysis of such cipher infeasible given the current computing and memory availability.

Performance Characterization of Lattice-Based Cryptography Workloads

2020 IEEE International Symposium on Performance Analysis of Systems and Software (ISPASS), 2020
In the domain of lattice cryptography, an emerging field of post-quantum secure cryptography, very few accelerator designs exist that both sufficiently accelerate a particular lattice cryptosystem and provide enough flexibility to accommodate a variety of cryptographic schemes.

Proof of a Shuffle for Lattice-Based Cryptography

2017
In this paper we present the first proof of a shuffle for lattice-based cryptography which can be used to build a universally verifiable mix-net capable of mixing votes encrypted with a post-quantum algorithm, thus achieving long-term privacy. Universal verifiability is achieved by means of the publication of a non-interactive zero knowledge proof of a

Lattice-Based Cryptography and NTRU

2021
With the publication of Peter Shor’s seminal paper that factoring and discrete log computations would be entirely feasible on a quantum computer, and with advances in the building of quantum computers, there has been a focus on what is referred to as “post-quantum cryptography”.

Towards Efficient Lattice-Based Cryptography

2011
In der Kryptographie ist eine der wesentlichen Aufgaben die Suche nach schweren Instanzen eines Berechnungsproblems, von dem man weiß, dass es im Worst-Case schwer ist. In der Gitterkryptographie sind wir in der einzigartigen Situation, einen Weg gefunden zu haben wie man zufällige Instanzen auswählt, die mindestens genauso schwer wie wohluntersuchte ...

Efficient arithmetic for lattice-based cryptography

Proceedings of the Twelfth IEEE/ACM/IFIP International Conference on Hardware/Software Codesign and System Synthesis Companion, 2017
Lattice-based cryptography is a promising family of post quantum algorithms. Contrary to other approaches, lattice-based primitives are extremely versatile and allow the realisation of several essential cryptographic primitives, such as encryption and digital signatures.

Improvement of Lattice-Based Cryptography Using CRT

2010
In this paper, we first critically analyze two existing lattice-based cryptosystems, namely GGH and Micciancio, and identify their drawbacks. Then, we introduce a method for improving the implementation of GGH using the Chinese Remainder Theorem (CRT). Furthermore, we also propose another cryptosystem optimized for CRT, drawing on the strengths of both

Practice-Oriented Techniques in Lattice-Based Cryptography

2020
In today’s computerised world, billions of people rely heavily on security systems that protect a tremendous amount of sensitive information ranging from banking information to government secrets. The algorithms currently used in such systems rely on classical cryptographic assumptions that do not provide security against powerful quantum computers. In

Gaussian sampling in lattice-based cryptography

Le Gaussian sampling dans la cryptographie sur les réseaux euclidiens Bien que relativement récente, la cryptographie à base de réseaux euclidiens s’est distinguée sur de nombreux points, que ce soit par la richesse des constructions qu’elle permet, par sa résistance supposée à l’avènement des ordinateursquantiques ou par la rapidité ...
