      [CRYPTO] xts: XTS blockcipher mode implementation without partial blocks · f19f5111
      由 Rik Snel 提交于 
      XTS currently considered to be the successor of the LRW mode by the IEEE1619
workgroup. LRW was discarded, because it was not secure if the encyption key
itself is encrypted with LRW.

XTS does not have this problem. The implementation is pretty straightforward,
a new function was added to gf128mul to handle GF(128) elements in ble format.
Four testvectors from the specification
	http://grouper.ieee.org/groups/1619/email/pdf00086.pdf
were added, and they verify on my system.

      [CRYPTO] aead: Add authenc · 3c09f17c
      由 Herbert Xu 提交于 
      This patch adds the authenc algorithm which constructs an AEAD algorithm
from an asynchronous block cipher and a hash.  The construction is done
by concatenating the encrypted result from the cipher with the output
from the hash, as is used by the IPsec ESP protocol.

The authenc algorithm exists as a template with four parameters:

	authenc(auth, authsize, enc, enckeylen).

The authentication algorithm, the authentication size (i.e., truncating
the output of the authentication algorithm), the encryption algorithm,
and the encryption key length.  Both the size field and the key length
field are in bytes.  For example, AES-128 with SHA1-HMAC would be
represented by

	authenc(hmac(sha1), 12, cbc(aes), 16)

The key for the authenc algorithm is the concatenation of the keys for
the authentication algorithm with the encryption algorithm.  For the
above example, if a key of length 36 bytes is given, then hmac(sha1)
would receive the first 20 bytes while the last 16 would be given to
cbc(aes).

      [CRYPTO] api: Add aead crypto type · 1ae97820
      由 Herbert Xu 提交于 
      This patch adds crypto_aead which is the interface for AEAD
(Authenticated Encryption with Associated Data) algorithms.

AEAD algorithms perform authentication and encryption in one
step.  Traditionally users (such as IPsec) would use two
different crypto algorithms to perform these.  With AEAD
this comes down to one algorithm and one operation.

Of course if traditional algorithms were used we'd still
be doing two operations underneath.  However, real AEAD
algorithms may allow the underlying operations to be
optimised as well.

      [CRYPTO] seed: New cipher algorithm · e2ee95b8
      由 Hye-Shik Chang 提交于 
      This patch adds support for the SEED cipher (RFC4269).

This patch have been used in few VPN appliance vendors in Korea for
several years.  And it was verified by KISA, who developed the
algorithm itself.

As its importance in Korean banking industry, it would be great
if linux incorporates the support.
