The Ring-LWE Problem in Lattice-Based Cryptography: The Case of Twisted Embeddings
Autor: Jheyne N. Ortiz, Robson R. de Araujo, Diego F. Aranha, Sueli I. R. Costa, Ricardo Dahab
Publikováno v: Entropy, Vol 23, Iss 9, p 1108 (2021)
Several works have characterized weak instances of the Ring-LWE problem by exploring vulnerabilities arising from the use of algebraic structures. Although these weak instances are not addressed by worst-case hardness theorems, enabling other ring in

Evaluation of CRYSTALS-Kyber and Saber on the ARMv8 architecture
Autor: Jheyne N. Ortiz, Félix Carvalho Rodrigues, Décio Gazzoni Filho, Caio Teixeira, Julio López, Ricardo Dahab
Publikováno v: Anais do XXII Simpósio Brasileiro de Segurança da Informação e de Sistemas Computacionais (SBSeg 2022).
This paper presents preliminary experimental results for the implementation of the third-round NIST finalists CRYSTALS-Kyber and Saber on the ARMv8 architecture. Our implementation uses NEON instructions to speed up key generation, encapsulation, and

Understanding How to Use Static Analysis Tools for Detecting Cryptography Misuse in Software
Autor: Ricardo Dahab, Nuno Laranjeiro, Marco Vieira, Nuno Antunes, Alexandre Braga
Publikováno v: IEEE Transactions on Reliability. 68:1384-1403
The use of cryptography is nowadays common in software systems, with cryptographic libraries widely available to software developers. As such, the likely weakest link in sensitive software has moved from cryptographic function implementations to the

High-performance Implementation of Elliptic Curve Cryptography Using Vector Instructions
Autor: Ricardo Dahab, Armando Faz-Hernández, Julio López
Publikováno v: ACM Transactions on Mathematical Software. 45:1-35
Elliptic curve cryptosystems are considered an efficient alternative to conventional systems such as DSA and RSA. Recently, Montgomery and Edwards elliptic curves have been used to implement cryptosystems. In particular, the elliptic curves Curve2551

Using Graph Embeddings and Machine Learning to Detect Cryptography Misuse in Source Code
Autor: Ricardo Dahab, Gustavo Eloi de P. Rodrigues, Alexandre Braga
Publikováno v: ICMLA
Cryptography is an essential aspect of software development. Nevertheless, software developers have limited knowledge of cryptography primitives, and support tools are limited. In this work, we present a comparison between graph embedding techniques,

A machine learning approach to detect misuse of cryptographic APIs in source code
Autor: Gustavo Eloi de P. Rodrigues, Alexandre M. Braga, Ricardo Dahab
Publikováno v: Anais do XX Simpósio Brasileiro de Segurança da Informação e de Sistemas Computacionais (SBSeg 2020).
Cryptography is an indispensable tool for achieving security requirements such as software security. However, most software developers do not have enough knowledge regarding the proper use of cryptography and its APIs. This leads to incorrect use and
