An algorithm is presented which implements a probabilistic attack on the key-exchange protocol based on permutation parity machines. Instead of imitating the synchronization of the communicating partners, the strategy consists of a Monte Carlo method to sample the space of possible weights during inner rounds and an analytic approach to convey the extracted information from one outer round to the next one. The results show that the protocol under attack fails to synchronize faster than an…

An Approach for Designing Neural Cryptography
TLDR
A generalized architecture to provide an approach to designing novel neural cryptography and by taking an in-depth investigation on the security of neural cryptography, a heuristic rule is proposed that can effectively guide us to designing secure neural cryptography.
Two-layer tree-connected feed-forward neural network model for neural cryptography
TLDR
A two-layer tree-connected feed-forward neural network (TTFNN) model for a neural protocol that captures the notion that two partners are capable of exchanging a vector with multiple bits in each time step is developed.
