One-step self-assembly fabrication of three-dimensional copper oxide/graphene oxide aerogel composite material for supercapacitors
Graphene oxide aerogel CuO Supercapacitor Self-assembly
<
2023/6/21
A cylindrical composite material of three-dimensional copper oxide/graphene oxide aerogel (3DCuO/GOA) has been successfully synthesized as a supercapacitor electrode material by a convenient one-step ...
We prove our result by reducing ff to (a variant of) the SINK-OF-VERIFIABLE-LINE problem, which is known to imply PPAD (and in fact CLS) hardness. The main building block of our reduction is a recentl...
On the Distribution of Quadratic Residues and Non-residues Modulo Composite Integers and Applications to Cryptography
Jacobi symbol probability distribution statistical distance
<
2019/6/4
We develop exact formulas for the distribution of quadratic residues and non-residues in sets of the form a+X={(a+x)modn∣x∈X}a+X={(a+x)modn∣x∈X}, where nn is a prime or the product of two primes and X...
Optimal TNFS-secure pairings on elliptic curves with composite embedding degree
Optimal ate pairing twists of elliptic curves jacobian coordinates

2019/3/21
Let pp be a small prime and n=n1n2>1n=n1n2>1 be a composite integer. For the function field sieve algorithm applied to FpnFpn, Guillevic (2019) had proposed an algorithm for initial splitting of the t...
Non-Interactive Zero-Knowledge Proofs for Composite Statements
Non-interactive zero-knowledge sigma protocols SNARK
<
2018/6/5
The two most common ways to design non-interactive zero-knowledge (NIZK) proofs are based on Sigma protocols and QAP-based SNARKs. The former is highly efficient for proving algebraic statements while...
