nss: Side channel attack on ECDSA signature generation

A flaw was found in nss. Using the EM side-channel, it is possible to extract the position of zero and non-zero wNAF digits while nss-certutil tool performs scalar multiplication during the ECDSA signature generation, leaking partial information about the ECDSA nonce. Given a small number of ECDS...

DEBIAN-CVE-2020-12402

During RSA key generation, bignum implementations used a variation of the Binary Extended Euclidean Algorithm which entailed significantly input-dependent flow. This allowed an attacker able to perform electromagnetic-based side channel attacks to record traces leading to the recovery of the secr...

PITA Side-Channel Crypto Key Attack

It’s unlikely that anyone envisioned the evolution of cryptographic key thievery to include leavened flatbread, but that’s where we’ve arrived. Researchers from Tel Aviv University in Israel are expected in September to present a paper at the Workshop on Cryptographic Hardware and Embedded System...
