We draw attention to a gap between theory and usage of nonce-based symmetric encryption, under which the way the former treats nonces can result in violation of privacy in the latter. We bridge the ga...
Reusing Nonces in Schnorr Signatures
public-key cryptography Schnorr digital signature efficiency
2018/1/19
The provably secure Schnorr signature scheme is popular and efficient. However, each signature requires a fresh modular exponentiation, which is typically a costly operation. As the increased uptake i...
Recovering OpenSSL ECDSA Nonces Using the FLUSH+RELOAD Cache Side-channel Attack
Side Channel Attack Cache ECDSA
2016/1/25
We illustrate a vulnerability introduced to elliptic curve cryptographic protocols when implemented using a function of the OpenSSL cryptographic library. For the given implementation using an ellipti...
