 NewDES - Wikipedia, the free encyclopedia
NewDES, unlike DES, has no bit-level permutations, making it easy to implement in software.
It is a product cipher, consisting of 17 rounds performed on a 64-bit data block and makes use of a 120-bit key.
NewDES has the same complementation property that DES has: namely, that if

In a related-key attack the attacker uses the fact that if the key is changed to a related key, there is some information he has about the resulting ciphertext without actually running the entire encryption algorithm.
In the case of NEWDES, this information comes from the fact that if the 15-byte key is rotated seven bytes, the expanded 60-byte key is also rotated seven bytes, which is exactly two round's worth of key.
Therefore the encryption algorithm using the rotated key does 17 rounds where the last 15 rounds are the same as the first 15 rounds using the un-rotated key.

 newdes encryption - yes there is newdes
i cant find the source to study the newdes algorithm...i'l have to do the encryption using visual c++...i cant even find the source code for this algorithm to make a reference.....thank u.....
newdes unlike des has no bit-level permutations,making it easy to implement in software....all operations are performed on whole bytes.
But you can also find different opinions which say that this algorithm is weaker than DES.

Further, applications such as NEWDES, which intersperse their code with normally benign INT 3's will fail with a GPF.
This allows normal debugging and NEWDES execution if the SoundBlaster drivers are loaded.
Hopefully there are not a number of SoundBlaster versions out there which use different GPF error codes.

NewDES has the same complementation property that DES : If EK(P) = C, then EK´(P´) = C´.
While this attack is time-consuming and largely theoretical, it shows that NewDES is weaker than DES.
It is efficient for software: no irritating permutations and all its operations work on bytes.

The cryptographic algorithms described in this book came from various sources, at various times, and were produced with both private and public sources of funding.
Several originate in the US, e.g., Lucifer, DES, NEWDES, SHA and MD-5.
DES and SHA are known to have been at least partially funded by the US Government as they are Federal Information Processing Standards (FIPS) maintained by the National Institute of Standards and Technology (NIST).
