Overview
The Data Encryption Standard (DES) is a 64-bit block cipher which uses a 56-bit
key to encrypt or decrypt each block of data. Given the short key length, DES has been
proven to be susceptible to brute force attacks and so is no longer considered secure for
general use.
Triple-DES (3DES) strengthens the security by combining three DES operations; an encrypt,
a decrypt, and a final encrypt; each using a 56-bit key. This increases the effective key length,
improving security. However, latterly 3DES has been superseded by the faster
Advanced Encryption Standard (AES) algorithm, although it still finds use in security
protocols such as IPsec and SSL/TLS for legacy purposes.
Helion DES & 3DES Solutions
Helion offer a range of solutions to implement the DES and 3DES algorithms, as
specified in NIST FIPS Publication 46-3, for use in either ASIC or Altera, Lattice,
Microsemi (Actel) or Xilinx FPGA. There are three versions to choose from; STANDARD, FAST
and GIGA, each providing a different area and performance trade-off to best match your
application.
The Helion DES/3DES cores have been designed to be extremely easy to integrate
into any target system and support both encryption and decryption, optionally with
either two or three key 3DES. They also offer full support for any of the common
block cipher modes e.g. ECB, CBC, CFB, OFB, and CTR.
