Attacking Deterministic Signature Schemes Using Fault Attacks [PDF]

open access: yes2018 IEEE European Symposium on Security and Privacy (EuroS&P), 2018
Many digital signature schemes rely on random numbers that are unique and non-predictable per signature. Failures of random number generators may have catastrophic effects such as compromising private signature keys. In recent years, many widely-used cryptographic technologies adopted deterministic signature schemes because they are presumed to be ...

A Fault Attack on ECDSA

2009 Workshop on Fault Diagnosis and Tolerance in Cryptography (FDTC), 2009
An advantage of schemes based on elliptic curve cryptography (ECC) is that they require a smaller key size than other public key schemes to guarantee the same level of security. Thus, ECC algorithms are well suited for systems with constrained resources like smart cards or mobile devices.

Faults, Injection Methods, and Fault Attacks

IEEE Design & Test of Computers, 2007
An active attacker can induce errors during the computation of the cryptographic algorithm and exploit the faulty results to extract information about the secret key in embedded systems. We call this kind of attack a fault attack. Fault attacks can break an unprotected system more quickly than any other kind of side-channel attack such as simple power ...
