Design of a New Lightweight Stream Cipher VHFO Algorithm

摘要

This paper designed the lightweight stream ciphers named VHFO. It used OFB. The key-stream size is 128-bit while the IV is specified to be 128 bits. Our security evaluation shows that VHFO can achieve enough security margin against known attacks. The implementation efficiency of both software and hardware based on VHFO is higher than others in RFID environment.
