On the Development of an Optimal Structure of Tree Parity Machine for the Establishment of a Cryptographic Key

Algorithm 2

Pseudocode geometric attack.

Data: outA, outB, outE, input, weightE

Result: none

1 initialization;

2 if != then

3  sigmaAbs abs(sum(input weightE));

4  sigmaSign sign(sum(input weightE));

5  sigmaSign[sigmaAbs.min()]

   -sigmaSign[sigmaAbs.min()];

6  tau prod(sigmaSign);

7  update(tau);
