New findings from the expedition, funded largely by the U.S. National Science Foundation with contributions from more than 20 partner nations, were recently published in the Geological Society of Amer...
Soybean Oil Modified Bio-based Poly(vinyl alcohol)s via Ring-Opening Polymerization
Biodegradable properties Epoxidized soybean oil Modification Poly(vinyl alcohol)
2024/3/4
In this paper, a simple method to modify the poly(vinyl alcohol) (PVA) through ring-opening reaction of epoxidized soybean oil (ESBO), catalyzed by hydrochloric acid is reported. The effect of ESBO lo...
A hash function family is called correlation intractable if for all sparse relations, it hard to find, given a random function from the family, an input output pair that satisfies the relation. Correl...
Traceable and linkable ring signatures, traceable range proofs and applications on regulatable privacy-preserving blockchains
regulatable blockchain privacy preserving decentralization
2019/8/19
Privacy protection has been extensively studied in the current blockchain research field. As representations, Monero and Zerocash have realized completely anonymous and amount-hiding transactions. How...
Module-LWE versus Ring-LWE, Revisited
Lattice-based Cryptography Security Reduction Cyclotomic Fields
2019/8/19
Till now, the only reduction from the module learning with errors problem (MLWE) to the ring learning with errors problem (RLWE) is given by Albrecht et al.et al. in ASIACRYPT 20172017. Reductions fro...
Many cryptographic schemes have been proposed from learning with errors problems over some rings (Ring-LWE). Polynomial time quantum reduction from the approximating Shortest Independent Vectors Probl...
Onion Ring ORAM: Efficient Constant Bandwidth Oblivious RAM from (Leveled) TFHE
Homomorphic Encryption Oblivious RAM
2019/6/24
Oblivious RAM (ORAM) is a cryptographic primitive that allows a client to hide access pattern to its data encrypted and stored at a remote server. Traditionally, ORAM algorithms assume the server acts...
We describe an efficient linkable ring signature scheme, compact linkable spontaneous anonymous group (CLSAG) signatures, for use in confidential transactions. Compared to the existing signature schem...
Cryptanalysis of Ring Homomorphic Encryption Schemes
