Picnic with Friends: Constructing post quantum digital signature schemes [PDF]

, 2021
Det digitale signatursystemet, Picnic [5], er et post-kvantesystem som ble introdusert som en del av NIST-prosessen for å standardisere post-kvantekryptografi [15]. Vi ser på hvordan Picnic er konstruert, og sikkerhetsegenskapene til systemet.

The MALICIOUS Framework: Embedding Backdoors into Tweakable Block Ciphers [PDF]

, 2021
Inserting backdoors in encryption algorithms has long seemed like a very interesting, yet difficult problem. Most attempts have been unsuccessful for symmetric-key primitives so far and it remains an open problem how to build such ciphers. In this work,

SANNS: Scaling Up Secure Approximate k-Nearest Neighbors Search [PDF]

, 2020
The $k$-Nearest Neighbor Search ($k$-NNS) is the backbone of several cloud-based services such as recommender systems, face recognition, and database search on text and images.

A Survey of Quantum-safe Digital Signatures and their building blocks [PDF]

, 2021
Sikkerhet og personvern på internett som vi kjenner i dag, er truet av den nye teknologien for å bygge større og kommersielle kvantecomputere. Selv om kvantecomputere som er bygget er relativt små, og ikke veldig effektive for å forstyrre Public Key ...

New Attacks on LowMC instances with a Single Plaintext/Ciphertext pair [PDF]

, 2021
Cryptanalysis of the LowMC block cipher when the attacker has access to a single known plaintext/ciphertext pair is a mathematically challenging problem.

Superposed epoch study of ICME sub-structures near Earth and their effects on galactic cosmic rays

, 2016
Interplanetary coronal mass ejections (ICMEs) are the interplanetary manifestations of solar eruptions. The overtaken solar wind forms a sheath of compressed plasma at the front of ICMEs.

Differential Power Analysis of the Picnic Signature Scheme [PDF]

, 2021
This work introduces the first differential side-channel analysis of the Picnic Signature Scheme, an alternate candidate in the ongoing competition for post-quantum cryptography by the National Institute of Standards and Technology (NIST).

Eliminating Variables in Boolean Equation Systems [PDF]

, 2017
Systems of Boolean equations of low degree arise in a natural way when analyzing block ciphers. The cipher's round functions relate the secret key to auxiliary variables that are introduced by each successive round.

A Survey on Homomorphic Encryption Schemes: Theory and Implementation

, 2017
Legacy encryption systems depend on sharing a key (public or private) among the peers involved in exchanging an encrypted message. However, this approach poses privacy concerns.

Implementing Grover oracles for quantum key search on AES and LowMC [PDF]

, 2023
Grover\u27s search algorithm gives a quantum attack against block ciphers by searching for a key that matches a small number of plaintext-ciphertext pairs. This attack uses $O(\sqrt{N})$ calls to the cipher to search a key space of size $N$.
