	RSA Security - 3.2.7 What is DESX?
		DESX is a strengthened variant of DES supported by RSA Security's toolkits (see Question 5.2.3).
		The difference between DES and DESX is that, in DESX, the input plaintext is bitwise XORed with 64 bits of additional key material before encryption with DES and the output is also bitwise XORed with another 64 bits of key material.
		The security of DESX against differential and linear attack (see Question 2.4.5) appears to be equivalent to that of DES with independent subkeys (see Question 3.2.8) so there is not a great increase in security with regards to these attacks.

	DES Is Dead. Long Live...Well, Um, What? \| March 22, 1999 (Site not responding. Last check: 2007-10-13)
		DESX is DES with an extra 56-bit key "XORed" in before the DES operation.
		DESX is as fast as DES and uses DES hardware, but it is significantly stronger.
		A brute-strength attack against DESX would be against its 112 bits worth of keys.

	DES-X - Wikipedia, the free encyclopedia
		In cryptography, DES-X (or DESX) is a variant on the DES (Data Encryption Standard) block cipher intended to increase the complexity of a brute force attack using a technique called key whitening.
		The original DES algorithm was specified in 1976 with a 56-bit key size: 2

		However, Biham and Shamir showed that G-DES with the recommended parameter sizes is easily broken and that any alterations of G-DES parameters that result in a cipher faster than DES are less secure than DES.
		DESX, another variant of DES, is supported by RSA Data Security's toolkits (
		The only difference between DES and DESX is that the input plaintext is exclusive-ored with 64 bits of key material before encryption with DES and the output is exclusive-ored with 64 bits of either related or unrelated key material.

	Recovering encrypted files from an NTFS partition
		DESX is a standard algorithm used by anyone who attempts to decrypt the file.
		The trick is that DESX doesn't work without a file encryption key.
		Since the file encryption key actually resides on the same system as the encrypted files, this key is vulnerable to compromise.

		RC4 was a secret algorithm until it was posted to Cypherpunks in October 1994, where some discussion took place (see Cypherpunks Archive).
		DESX is a slightly strengthened version of DES.

		The exportable version comes with 40-bit DESX ("40-bit keys (..) are expanded to the required 128 bits for DESX").
		Recall that DESX uses 184 bits of keying material.
		IF 56 bits of either one of the whitening keys are zero, it is easy to see that the security of the "128-bit" DESX would be around 2^64 (the attack requires only two known plaintext blocks).

	Windows Encrypted File System: Replace DESX algorithm with 3DES
		The Microsoft default DESX encryption algorithm can be replaced with the 3DES algorithm for EFS only.
		When 3DES is enabled, files encrypted by using both the DESX and 3DES algorithms can be decrypted.
		However, all new files are encrypted by using the 3DES algorithm.

	How to Protect DES Against Exhaustive Key Search - Kilian, Rogaway (ResearchIndex)
		If your firewall is blocking outgoing connections to port 3125, you can use these links to download local copies.
		Abstract: The block cipher DESX is defined by DESX k:k1:k2 (x) = k2 \Phi DES k (k1 \Phi x), where \Phi denotes bitwise exclusive-or.
		We show that, when F is an idealized block cipher, FX k:k1:k2 (x) = k2 \Phi F k (k1 \Phi x) is substantially more resistant to key search than is F.

	Tuning EFS
		EFS uses a symmetric cipher (Advanced Encryption Standard—AES; Triple DES—3DES; or DESX) to perform the bulk encryption and an asymmetric cipher (RSA) to provide secure storage of the bulk encryption key.
		AES uses a 256-bit symmetric encryption key, 3DES uses a 128-bit key, and DESX uses a 56-bit key.
		The 256-bit AES cipher is the best and most secure option for EFS symmetric encryption, followed by 128-bit 3DES, then 56-bit DESX.
