Hello,
I am using the function
B = sage.crypto.lattice.gen_lattice('modular',n,m,q).
It generates the basis of row vectors of a hard lattice based on the Ajtai[96]
paper, as mentioned in the references.
I wanted the random matrix(parity check matrix) 'A' used to generate this hard
lattice, so went through the source code lattice.py to compute 'A' along with
the basis vectors as in described there.
A is a m x n and B is a m x m matrix.
As B is a hard random lattice,
for every i, B.row(i) * A should be 0(1 x n)
But it does not hold.
Any help regarding this or pointers where I might be going wrong?
Thanks,
Rohan
