We studied the most secure static encrypted nonce variant of "MIFARE Classic compatible" cards -- meant to resist all known card-only attacks -- and developed new attacks defeating it, uncovering a hardware backdoor in the process. And that's only the beginning...
NIST has formally published three post-quantum cryptography standards from the competition it held to develop cryptography able to withstand the anticipated quantum computing decryption of current asymmetric encryption.
Today, the National Institute of Standards and Technology (NIST) announced the first standardization of three cryptography schemes that are immune against the threat of quantum computers, known as post-quantum cryptography (PQC) schemes. With these standards in hand, NIST is encouraging computer system administrators to begin transitioning as soon as possible.
A group of Chinese researchers have just published a paper claiming that they can—although they have not yet done so—break 2048-bit RSA. This is something to take seriously. It might not be correct, but it’s not obviously wrong.
