What is a lattice attack?

digital signatures, lattices We describe a lattice attack on the Digital Signature Algorithm (DSA) when used to sign many messages, mi , under the assumption that a proportion of the bits of each of the associated ephemeral keys, yi, can be recovered by alternative techniques.

Is NTRU quantum resistant?

Resistance to quantum-computer-based attacks Unlike RSA and Elliptic Curve Cryptography, NTRU is not known to be vulnerable to quantum computer based attacks. However the Stehle-Steinfeld version of NTRU is “significantly less efficient than the original scheme.”

Why we use lattice-based cryptography?

Lattice-based cryptographic constructions are the leading candidates for public-key post-quantum cryptography. Many lattice-based cryptographic schemes are known to be secure assuming the worst-case hardness of certain lattice problems.

What is a lattice in group theory?

In geometry and group theory, a lattice in is a subgroup of the additive group which is isomorphic to the additive group , and which spans the real vector space . In other words, for any basis of. , the subgroup of all linear combinations with integer coefficients of the basis vectors forms a lattice.

Who invented quantum cryptography?

Stephen Wiesner
Quantum cryptography was proposed first by Stephen Wiesner, then at Columbia University in New York, who, in the early 1970s, introduced the concept of quantum conjugate coding.

What is plaintext and ciphertext?

If you can make sense of what is written, then it is in plaintext. Ciphertext, or encrypted text, is a series of randomized letters and numbers which humans cannot make any sense of. An encryption algorithm takes in a plaintext message, runs the algorithm on the plaintext, and produces a ciphertext.

What is NTRU prime?

Within the NTRU Prime project, Streamlined NTRU Prime is a small lattice-based KEM aiming for the standard goal of IND-CCA2 security. There are other proposals of small lattice-based KEMs aiming for IND-CCA2, but Streamlined NTRU Prime is systematically designed to minimize the complexity of a thorough security review.
