New Protocols for Secure Linear Algebra: Pivoting-Free Elimination and Fast Block-Recursive Matrix Decomposition
secure linear algebra multiparty computation
2018/8/2
Cramer and Damgård were the first to propose a constant-rounds protocol for securely solving a linear system of unknown rank over a finite field in multiparty computation (MPC). For mm linear equ...
A Matrix Decomposition Method for Optimal Normal Basis Multiplication
Finite fields matrix decomposition method
2015/12/24
We introduce a matrix decomposition method and prove that multiplication in GF(2^k) with a Type 1 optimal normal basis for can be performed using k^2-1 XOR gates irrespective of the choice of the irre...
