Learning with errors cryptography
In cryptography, Learning with errors (LWE) is a mathematical problem that is widely used in cryptography to create secure encryption algorithms. It is based on the idea of representing secret information as a set of equations with errors. In other words, LWE is a way to hide the value of a secret by introducing noise to it. In … Se mer Denote by $${\displaystyle \mathbb {T} =\mathbb {R} /\mathbb {Z} }$$ the additive group on reals modulo one. Let $${\displaystyle \mathbf {s} \in \mathbb {Z} _{q}^{n}}$$ be a fixed vector. Let $${\displaystyle \phi }$$ be … Se mer The LWE problem serves as a versatile problem used in construction of several cryptosystems. In 2005, Regev showed that the decision … Se mer The LWE problem described above is the search version of the problem. In the decision version (DLWE), the goal is to distinguish between noisy inner products and uniformly random … Se mer Regev's result For a n-dimensional lattice $${\displaystyle L}$$, let smoothing parameter The discrete … Se mer • Post-quantum cryptography • Lattice-based cryptography • Ring learning with errors key exchange Se mer NettetWith billions of devices connected over the internet, the rise of sensor-based electronic devices have led to cloud computing being used as a commodity technology service. These sensor-based devices are often small and limited by power, storage, or compute capabilities, and hence, they achieve these capabilities via cloud services. However, …

NettetAbstract. A fully homomorphic encryption (FHE) scheme allows anyone to transform an encryption of a message, m, into an encryption of any (efficient) function of that message, f ( m), without knowing the secret key. We present a leveled FHE scheme that is based solely on the (standard) learning with errors ( L W E) assumption.
