The quest for accurate exchange-correlation functionals has long remained a grand challenge in density functional theory (DFT), as it describes the many-electron quantum mechanical behavior through a ...
On the Data Limitation of Small-State Stream Ciphers: Correlation Attacks on Fruit-80 and Plantlet
Small-state stream cipher Grain Correlation attack
2019/7/15
Many cryptographers have focused on lightweight cryptography, and a huge number of lightweight block ciphers have been proposed. On the other hand, designing lightweight stream ciphers is a challengin...
Fast Correlation Attacks on Grain-like Small State Stream Ciphers and Cryptanalysis of Plantlet, Fruit-v2 and Fruit-80
Fast correlation attack Stream cipher Grain-like
2019/7/8
The fast correlation attack (FCA) is one of the most important cryptanalytic techniques against LFSR-based stream ciphers. In CRYPTO 2018, Todo et al. found a new property for the FCA and proposed a n...
Efficient Pseudorandom Correlation Generators: Silent OT Extension and More
Secure computation correlated randomness pseudorandom correlation generator
2019/5/9
Secure multiparty computation (MPC) often relies on sources of correlated randomness for better efficiency and simplicity. This is particularly useful for MPC with no honest majority, where input-inde...

2019/4/1
Elliptic curves based algorithms are nowadays widely spread among embedded systems. They indeed have the double advantage of providing efficient implementations with short certi cates and of being rel...
Security Evaluation for Snow 2.0-like Stream Ciphers Against Correlation Attacks over Extension Fields
symmetric cryptography stream cipher correlation attack
2019/3/20
We propose a general method for security evaluation of SNOW 2.0-like ciphers against correlation attacks that are built similarly to known attacks on SNOW 2.0. Unlike previously known methods, the met...
