Plane normal dot products

P = [ 1  c ]
    [ c  1 ]

Plane normals

Dealing with a system of equations with more unknowns than equations by making some of the unknowns parameters and using Gaussian elimination to solve for the remaining ones.

2a + 3b = 4c
5a + 6b + 42 = 7d

Arbitrarily, make b and d parameters and solve for a and c:

I made the assumption that most of the adjacent values of the original signal are somewhat close,

x[n] ≈ x[n−1].

If the “encrypted” y[64n+k] = x[64n+k] xor key[k], then

y[64n+k] xor key[k] ≈ y[64n+k−1] xor key[k−1].
