A machine-learning approach finding treatment options Covid-1
2021/3/5
When the COVID-19 pandemic struck in early 2020, doctors and researchers rushed to find effective treatments. There was little time to spare. "Making new drugs takes forever," says Caroline Uhler, a c...
Studies led by researchers at The University of Texas Southwestern Medical Center are shedding light on the biology and potential vulnerabilities of schistosomes -- parasitic flatworms that cause the ...

Side-channel Attack Post-quantum Cryptography Code-based Cryptography
2019/7/15
In the last few years, post-quantum cryptography has received much attention. NIST is running a competition to select some post-quantum schemes as standard. As a consequence, implementations of post-q...
Finding a Nash Equilibrium Is No Easier Than Breaking Fiat-Shamir
TFNP PPAD Nash Equilibrium
2019/5/23
The Fiat-Shamir heuristic transforms a public-coin interactive proof into a non-interactive argument, by replacing the verifier with a cryptographic hash function that is applied to the protocol’s tra...
Quantum cryptanalysis in the RAM model: Claw-finding attacks on SIKE
quantum cryptanalysis SIDH
2019/2/27
We introduce models of computation that enable direct comparisons between classical and quantum algorithms. Incorporating previous work on quantum computation and error correction, we justify the use ...
Improved Quantum Multicollision-Finding Algorithm
post-quantum cryptography quantum algorithm multiclaw
2018/11/21
The current paper improves the number of queries of the previous quantum multi-collision nding algorithms presented by Hosoyamada et al. at Asiacrypt 2017. Let ll-collision be ll distinct inputs that...
A kk-collision for a compressing hash function HH is a set of kk distinct inputs that all map to the same output. In this work, we show that for any constant kk, Θ(N12(1−12k−1))Θ(N12(1W...
Finding Collisions in a Quantum World: Quantum Black-Box Separation of Collision-Resistance and One-Wayness
post-quantum cryptography one-way permutation one-way trapdoor permutation
2018/11/12
Since the celebrated work of Impagliazzo and Rudich (STOC 1989), a number of black-box impossibility results have been established. However, these works only ruled out classical black-box reductions a...
IMPROVED PUBLIC TRANSIT ROUTING ALGORITHM FOR FINDING THE SHORTEST K-PATH
Public transit routing Timetable Transfer penalty Multiple paths imilar paths
2018/11/9
Most of the existing public transit routing algorithms were developed on the basis of graph theory. Recently, algorithms are being developed that can compute for O-D public transit paths by using time...
Finding Ordinary Cube Variables for Keccak-MAC with Greedy Algorithm
Keccak Keccak-MAC ordinary cube variables
2018/9/6
In this paper, we present an alternative method to choose ordinary cube variables for Keccak-MAC. Firstly, we choose some good candidates for ordinary cube variables with key-independent conditions. T...
