Description: 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 Platform: |

Description: In cryptography, the International Data Encryption Algorithm (IDEA), originally called Improved Proposed Encryption Standard (IPES), is a symmetric-key block cipher designed by James Massey of ETH Zurich and Xuejia Lai and was first described in 1991. The algorithm was intended as a replacement for the Data Encryption Standard (DES). IDEA is a minor revision of an earlier cipher, Proposed Encryption Standard (PES).
The cipher was designed under a research contract with the Hasler Foundation, which became part of Ascom-Tech AG. The cipher was patented in a number of countries but was freely available for non-commercial use. The name “IDEA” is also a trademark. The last patents expired in 2012 and IDEA is now patent-free and thus free to use.[2][3]
IDEA was used in Pretty Good Privacy (PGP) v2.0, and was incorporated after the original cipher used in v1.0, BassOmatic, was found to be insecure.[4] IDEA is an optional algorithm in the OpenPGP standard. Platform: |

Description: In cryptography, the IDEA NXT algorithm (previously known as FOX) is a block cipher designed by Pascal Junod and Serge Vaudenay of EPFL (Lausanne, Switzerland). It was conceived between 2001 and 2003, the project was originally named FOX and was published in 2003. In May 2005 it was announced by MediaCrypt under the name IDEA NXT. IDEA NXT is the successor to the International Data Encryption Algorithm (IDEA) and also uses the Lai-Massey scheme.[2] MediaCrypt AG holds patents on elements of IDEA[citation needed] and IDEA NXT. The cipher is specified in two configurations: NXT64 (with block of 64 bits, key of 128 bits, 16 rounds) and NXT128 (with block of 128 bits, key of 256 bits, 16 rounds). Platform: |
