Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Building private information retrieval schemes over binary fields
二进制字段 私有信息 检索方案
2023/4/21
The private information retrieval (PIR) problem was first proposed by Chor et al. in 1995, and it is a canonical problem in the study of privacy issues that arise from the retrieval of information fro...
A new class of irreducible pentanomials for polynomial based multipliers in binary fields
irreducible pentanomials polynomial multiplication modular reduction
2018/6/5
We give the total cost of the multiplier and found that the bit-parallel multiplier defined by this new class of polynomials has improved XOR and AND complexity. Our multiplier has comparable time del...
Fast Scalar Multiplication for Elliptic Curves over Binary Fields by Efficiently Computable Formulas
binary elliptic curves point multiplication lambda coordinates
2017/9/7
This paper considers efficient scalar multiplication of elliptic curves over binary fields with a twofold purpose. Firstly, we derive the most efficient 3P3P formula in λλ-projective coordinates and 5...

2015/8/5
Our scheme can be used to authenticate linear transformations of signed data, such as those arising when computing mean and least squares fit or in networks that use network coding. Our construction g...
Homomorphic Signatures over Binary Fields: Secure Network Coding with Small Coefficients
Lattice-based cryptography homomorphic signatures network coding
2010/8/26
We propose a new signature scheme that can be used to authenticate data and prevent pollution attacks in networks that use network coding. At its core, our system is a homomorphic signature scheme tha...

In this article, we deal with fast arithmetic in the Picard group
of hyperelliptic curves of genus 3 over binary fields. We investigate both the
optimal performance curves, where h(x) = 1, and the m...

2009/6/5
Galbraith, Lin and Scott recently constructed efficiently-computable endomorphisms
for a large family of elliptic curves defined over Fq2 and showed, in the case where q is prime, that
the Gallant-L...

2009/6/3
Multiple-point multiplication on elliptic curves is
the highest computational complex operation in the elliptic curve
cyptographic based digital signature schemes. We describe three
algorithms for ...
Efficient Tate Pairing Computation for Supersingular Elliptic Curves over Binary Fields
supersingular elliptic curve Tate pairing divisor
2009/4/1
After Miller's original algorithm for the Tate pairing computation, many improved
algorithms have been suggested, to name just a few, by Galbraith et al. and Barreto et al.,
especially for the field...

2009/2/18
The most important and expensive operation in a hyperelliptic curve cryptosystem
(HECC) is scalar multiplication by an integer k, i.e., computing an integer k times a divisor D on the Jacobian. Using...
