Gargantuan hail Argentina smashed world record
2020/5/9
A supercell thunderstorm pelted a city center in Argentina with hailstones so large that scientists have suggested a new category to describe them -- gargantuan hail.National Science Foundation-funded...
In 2019, the hole that developed in the ozone layer over Antarctica was the smallest on record since the ozone hole was first discovered, according to scientists at NASA and the US National Ocean...

Rocks asteroid impact site record first day dinosaur extinction
2019/10/18
When the asteroid that wiped out the dinosaurs slammed into the planet, the impact set wildfires, triggered tsunamis and blasted so much sulfur into the atmosphere that it blocked the sun, which cause...
SIKE Round 2 Speed Record on ARM Cortex-M4
Post-quantum cryptography SIKE key encapsulation mechanism
2019/5/23
We present the first practical software implementation of Supersingular Isogeny Key Encapsulation (SIKE) round 2, targeting NIST’s 1, 2, and 5 security levels on 32-bit ARM Cortex-M4 microcontrollers....
Yet Another Size Record for AES: A First-Order SCA Secure AES S-box Based on GF($2^8$) Multiplication
side-channel analysis Threshold Implementation AES
2018/11/12
It is well known that Canright’s tower field construction leads to a very small, unprotected AES S-box circuit by recursively embedding Galois Field operations into smaller fields. The current size re...
Partially specified channels: The TLS 1.3 record layer without elision
cryptographic standards TLS 1.3 stream-based channels
2018/7/2
This work advances the study of secure stream-based channels (Fischlin et al., CRYPTO ’15) by considering the multiplexing of many data streams over a single channel. This is an essential feature of r...
How to Record Quantum Queries, and Applications to Quantum Indifferentiability
quantum indifferentiability
2018/3/23
The quantum random oracle model (QROM) has become the standard model in which to prove the post-quantum security of random-oracle-based constructions. Unfortunately, none of the known proof techniques...
