A comprehensive analysis of constant-time polynomial inversion for post-quantum cryptosystems

Alessandro Barenghi, Gerardo Pelosi
2020 Proceedings of the 17th ACM International Conference on Computing Frontiers  
We evaluate advantages and shortcomings of the different inversion algorithms, including their capability to run in constant-time, thus preventing timing side-channel attacks.  ...  Post-quantum cryptosystems have currently seen a surge in interest thanks to the current standardization initiative by the U.S.A. National Institute of Standards and Technology (NIST).  ...  The three systems employ a binary QC-MDPC code having a systematic public parity-check matrix representation.  ...

A Generic Attack on Lattice-based Schemes using Decryption Errors with Application to ss-ntru-pke [article]

Qian Guo, Thomas Johansson, Alexander Nilsson
2019 IACR Cryptology ePrint Archive  
In this paper we propose and discuss a generic attack for secret key recovery based on generating decryption errors.  ...  In a standard PKC setting, the model first consists of a precomputation phase where special messages and their corresponding error vectors are generated.  ...  For this setting, Guo, Johansson and Stankovski [13] , proposed a key-recovery attack against the CCA-secure version of QC-MDPC, which is a code-based scheme.  ...

DAGS: Key encapsulation using dyadic GS codes

2018 Journal of Mathematical Cryptology  
In this paper, we introduce DAGS, a Key Encapsulation Mechanism (KEM) based on quasi-dyadic generalized Srivastava codes.  ...  We believe that DAGS will offer competitive performance, especially when compared with other existing code-based schemes, and represent a valid candidate for post-quantum standardization.  ...  There is a one-to-one correspondence between these roots and the error positions: in fact, there is an error in position i if and only if σ(1/x i ) = 0.  ...

2020 arXiv   pre-print
This report elaborates a key encapsulation mechanism (KEM), namely Classic McEliece, based on algebraic coding theory to establish a symmetric key for two users.  ...  This article addresses code-based cryptography and is designed to depict the complete outline of a code based public key cryptosystem.  ...  We say that a KEM is secure under adaptive chosen ciphertext attacks if the advantage Adv KEM of any polynomial time adversary A in the above CCA model is negligible.  ...

Paolo Santini, Edoardo Persichetti, Marco Baldi
2018 IACR Cryptology ePrint Archive  
Some families of F-reproducible codes have the property that they can be entirely generated from a small number of signature vectors, and consequently admit matrices that can be described in a very compact  ...  We then consider some cryptographic applications of codes of this type and show that their use can be advantageous for hindering some current attacks against cryptosystems relying on structured codes.  ...  Acknowledgements Authors Edoardo Persichetti and Paolo Santini were supported by National Science Foundation (NSF) grant CNS-1906360 Bibliography [1] [2]  ...
