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.

High-Performance Hardware Implementation of MPCitH and Picnic3

Transactions on Cryptographic Hardware and Embedded Systems
Picnic is a post-quantum digital signature, the security of which relies solely on symmetric-key primitives such as block ciphers and hash functions instead of number theoretic assumptions. One of the main concerns of Picnic is the large signature size.

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 ...

Efficient implementation of LowMC in HElib

, 2018
LowMC is a symmetric block cipher designed for fully homomorphic encryption. This thesis focuses on Martin Albrecht’s implementation of the cipher in the FHE library HElib, and how his implementation can be improved when encrypting a single plaintext.

Symmetric Ciphers for Fully Homomorphic Encryption [PDF]

, 2020
Fully homomorphic encryption is the latest addition to the world of cryptography. It is a type of encryption that allows operations to be done on ciphertexts, which is not possible with traditional encryption. The field has gained a lot of traction since

Memory-Efficient Single Data-Complexity Attacks on LowMC Using Partial Sets [PDF]

, 2022
The LowMC family of block ciphers was first proposed by Albrecht et al. in [ARS+15], specifically targeting adoption in FHE and MPC applications due to its low multiplicative complexity.

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 $N$.

New Attacks on LowMC Using Partial Sets in the Single-Data Setting

IACR Communications in Cryptology
The LowMC family of block ciphers was proposed by Albrecht et al. in Eurocrypt 2015, specifically targeting adoption in FHE and MPC applications due to its low multiplicative complexity. The construction operates a 3-bit quadratic S-box as the sole non-linear transformation in the algorithm.
