Lattice Decoding Attacks on Binary LWE [PDF]

, 2017
We consider the binary-LWE problem, which is the learning with errors problem when the entries of the secret vector are chosen from $\{ 0, 1\}$ or $\{ -1, 0, 1 \}$ (and the error vector is sampled from a discrete Gaussian distribution).

LWE and provably secure key exchange schemes

, 2019
The threat of large-scale quantum computers motivates cryptographers to base cryptosystems on problems believed to be resistant against quantum computers.

Hollow LWE: A New Spin

Updatable public-key encryption (UPKE) allows anyone to update a public key while simultaneously producing an update token, given which the secret key holder could consistently update the secret key. Furthermore, ciphertexts encrypted under the old public key remain secure even if the updated secret key is leaked – a property much desired in secure ...

Evasive LWE Assumptions: Definitions, Classes, and Counterexamples [PDF]

The evasive LWE assumption, proposed by Wee [Eurocrypt\u2722 Wee] for constructing a lattice-based optimal broadcast encryption, has shown to be a powerful assumption, adopted by subsequent works to construct advanced primitives ranging from ABE variants

Sublattice Attacks on LWE over Arbitrary Number Field Lattices [PDF]

, 2019
Learning with errors over algebraic integer rings (Ring-LWE) was introduced by Lyubashevsky, Peikert and Regev in Eurocrypt 2010 and has been served as the fundamental hard problem for lattice cryptogra- phy.

Effect of heat stress on the hypothalamic expression profile of water homeostasis‐associated genes in low‐ and high‐water efficient chicken lines

Physiological Reports
With climate change, selection for water efficiency and heat resilience are vitally important. We undertook this study to determine the effect of chronic cyclic heat stress (HS) on the hypothalamic expression profile of water homeostasis‐associated ...

Identity-Based Online/Offline Encryption Scheme from LWE

Information
With quantum computers, the quantum resistance of cryptographic systems has gradually attracted attention. To overcome the shortcoming of existing identity-based encryption (IBE) schemes in resisting quantum attacks, we introduce an IBE scheme based on ...

Improved Meet-LWE Attack via Ternary Trees [PDF]

The Learning with Errors (LWE) problem with its variants over structured lattices has been widely exploited in efficient post-quantum cryptosystems. Recently, May suggests the Meet-LWE attack, which poses a significant advancement in the line of work on ...
