Encryption algorithms are becoming
more necessary to ensure data is securely transmitted
over insecure communication channels. FOX is
a recently developed algorithm and its structure is
based on the already proven IDEA (International
Data Encryption Algorithm) cipher.
FOX is a symmetric (private key) block cipher. Its
top-level structure uses the Lai-Massey scheme and
the round functions used in the scheme are substitution
permutation networks (SPN). Its flexibility lies
in the fact that it can be efficiently implemented in
hardware and software. We report some of the first
results of implementing the cipher on an FPGA
