What is lattice model security?

In computer security, lattice-based access control (LBAC) is a complex access control model based on the interaction between any combination of objects (such as resources, computers, and applications) and subjects (such as individuals, groups or organizations).

What is quantum resistant cryptography?

Post-quantum cryptography (sometimes referred to as quantum-proof, quantum-safe or quantum-resistant) refers to cryptographic algorithms (usually public-key algorithms) that are thought to be secure against a cryptanalytic attack by a quantum computer. …

What is meant by cryptography?

Cryptography is the study of secure communications techniques that allow only the sender and intended recipient of a message to view its contents. The term is derived from the Greek word kryptos, which means hidden.

What is the lattice in physics?

In physics, a lattice model is a physical model that is defined on a lattice, as opposed to the continuum of space or spacetime. Lattice models originally occurred in the context of condensed matter physics, where the atoms of a crystal automatically form a lattice.

Which is the best description of lattice based cryptography?

Lattice-based cryptography. Lattice-based cryptography is the generic term for constructions of cryptographic primitives that involve lattices, either in the construction itself or in the security proof. Lattice-based constructions are currently important candidates for post-quantum cryptography.

Is the U.S.Government authorized to reprint lattice based cryptography?

The U.S. Government is authorized to reproduce and distribute reprints for governmental purposes notwithstanding any copyright notation thereon. Abstract Lattice-based cryptography is the use of conjectured hard problems on point lattices in Rnas the foundation for secure cryptographic systems.

Which is the best algorithm for lattice problems?

A more precise definition of SVP and several other lattice problems appears in Section 2. The most well known and widely studied algorithm for lattice problems is the LLL algorithm, developed in 1982 by Lenstra, Lenstra, and Lov´asz [39].

When did Oded Regev invent lattice based encryption?

The first lattice-based public-key encryption scheme whose security was proven under worst-case hardness assumptions was introduced by Oded Regev in 2005, together with the Learning with Errors problem (LWE). Since then, much follow-up work has focused on improving Regev’s security proof and improving the efficiency of the original scheme.
