Fault Attacks on Randomized RSA Signatures
Fault attacks exploit hardware malfunctions or induce them to recover secret keys embedded in a secure device such as a smart card. In the late 90’s, Boneh, DeMillo and Lipton [6] and other authors introduced fault-based attacks on crt-rsa which allow the attacker to factor the signer’s modulus when the message padding function is deterministic. Since then, extending fault attacks to randomized...
متن کاملFault Attacks Against emv Signatures
At ches 2009, Coron, Joux, Kizhvatov, Naccache and Paillier (cjknp) exhibited a fault attack against rsa signatures with partially known messages. This attack allows factoring the public modulus N . While the size of the unknown message part (ump) increases with the number of faulty signatures available, the complexity of cjknp’s attack increases exponentially with the number of faulty signatur...
متن کاملRevisiting SSL/TLS Implementations: New Bleichenbacher Side Channels and Attacks
As a countermeasure against the famous Bleichenbacher attack on RSA based ciphersuites, all TLS RFCs starting from RFC 2246 (TLS 1.0) propose “to treat incorrectly formatted messages in a manner indistinguishable from correctly formatted RSA blocks”. In this paper we show that this objective has not been achieved yet (cf. Table 1): We present four new Bleichenbacher side channels, and three suc...
متن کاملFault Attacks on RSA Signatures with Partially Unknown Messages
Fault attacks exploit hardware malfunctions to recover secrets from embedded electronic devices. In the late 90’s, Boneh, DeMillo and Lipton [6] introduced fault-based attacks on crt-rsa. These attacks factor the signer’s modulus when the message padding function is deterministic. However, the attack does not apply when the message is partially unknown, for example when it contains some randomn...
متن کاملDifferential Attacks on Deterministic Signatures
Deterministic signature schemes are becoming more popular, as illustrated by the deterministic variant of ECDSA and the popular EdDSA scheme, since eliminating the need for high-quality randomness might have some advantages in certain use-cases. In this paper we outline a range of differential fault attacks and a di erential power analysis attack against such deterministic schemes. This shows, ...
