Lightweight Key Exchange and Stream Cipher based solely on Tree Parity Machines.
Markus Volkmer, Sebastian Wallner · 2005
Secure key exchange is considered most critical and complex in this context and of major importance with regard to security. Regarding applications in embedded systems, asymmetric (public-key) group-based cryptosystems based on Elliptic Curve Cryptography (ECC), the generalization to Hyper-Elliptic Curves (see e.g. [6]) and hardware-specific extensions for efficient arithmetic [7] are stateof-the-art. Without a reduction of the security, these representations allow to reduce the size of the numbers to calculate with. Yet, more complex expressions
