2019/8/22
Deterministic generation of per-signature randomness has been a widely accepted solution to mitigate the catastrophic risk of randomness failure in Fiat-Shamir type signature schemes. However, recent ...
Exploiting Determinism in Lattice-based Signatures - Practical Fault Attacks on pqm4 Implementations of NIST candidates
Deterministic Lattice Signatures pqm4 Fault Attack
font style='font-size:12px;'>
2019/7/8
In this paper, we analyze the implementation level fault vulnerabilities of deterministic lattice-based signature schemes. In particular, we extend the practicality of skip-addition fault attacks thro...
On Misuse of Nonce-Misuse Resistance: Adapting Differential Fault Attacks on (few) CAESAR Winners
Fault Attacks DFA SPNs
font style='font-size:12px;'>
2019/5/31
In this paper, we study DFA attacks on some of the CAESAR competition winners. We study the challenges imposed by the design of these modes, such as masking of the ciphertext. We also show that a very...

2019/5/23
At ASIACRYPT 2018 it was shown that Statistical Ineffective Fault Attacks (SIFA) pose a threat for many practical implementations of symmetric cryptography. In particular, countermeasures against both...
Transform-and-Encode: A Countermeasure Framework for Statistical Ineffective Fault Attacks on Block Ciphers
Fault Attack Block Cipher Masking
font style='font-size:12px;'>
2019/5/23
Right from its introduction by Boneh et al., fault attacks (FA) have been established to be one of the most practical threats to both public key and symmetric key based cryptosystems. Statistical Inef...
Protecting ECC Against Fault Attacks: The Ring Extension Method Revisited
Elliptic curves formal groups degenerate curves
font style='font-size:12px;'>
2019/5/21
Due to its shorter key size, elliptic curve cryptography (ECC) is gaining more and more popularity. However, if not properly implemented, the resulting cryptosystems may be susceptible to fault attack...
Degenerate Fault Attacks on Elliptic Curve Parameters in OpenSSL
OpenSSL Elliptic curve cryptography Invalid curve attack
font style='font-size:12px;'>
2019/4/22
In this paper, we describe several practically exploitable fault attacks against OpenSSL's implementation of elliptic curve cryptography, related to the singular curve point decompression attacks of B...
To Infect Or Not To Infect: A Critical Analysis Of Infective Countermeasures In Fault Attacks

font style='font-size:12px;'>
2019/4/8
As fault based cryptanalysis is becoming more and more of a practical threat, it is imperative to make efforts to devise suitable countermeasures. In this regard, the so-called ``infective countermeas...
Fault Attacks on Nonce-based Authenticated Encryption: Application to Keyak and Ketje
Fault Attack Statistical Ineffective Fault Attack SIFA
font style='font-size:12px;'>
2018/11/15
In the context of fault attacks on nonce-based authenticated encryption, an attacker faces two restrictions. The first is the uniqueness of the nonce for each new encryption that prevents the attacker...
New Bleichenbacher Records: Practical Fault Attacks on qDSA Signatures
Digital Signature Fault Attack Bleichenbacher's Nonce Attack
font style='font-size:12px;'>
2018/5/2
In this paper, we optimize Bleichenbacher's statistical attack technique against (EC)DSA and other Schnorr-like signature schemes with biased or partially exposed nonces. Previous approaches to Bleich...
