Lightweight Key Exchange and Stream Cipher based solely on Tree Parity Machines
Markus Volkmer and Sebastian Wallner
Abstract: Alternative security solutions are considered in science and industry, motivated by the strong restrictions as they are often present in embedded security scenarios -- especially in a RFID setting. We investigate a low hardware-complexity cryptosystem for lightweight symmetric key exchange and stream cipher based on Tree Parity Machines. The speed of a key exchange is basically only limited by the channel capacity as is the stream cipher throughput. This work significantly improves and extends previously published results on TPMRAs. Again, characteristics of standard-cell ASIC design realizations as IP-core
in 0.18-micrometer-CMOS technology are evaluated.
Category / Keywords: secret-key cryptography / stream ciphers, key management, implementation
