The entropy in the CPU execution time jitter is magnified by the CPU Jitter Random Number Generator. The CPU Jitter Random Number Generator uses the CPU execution timing jitter to generate a bit stream which complies with different statistical measurements that determine the bit stream is random. The CPU Jitter Random Number Generator delivers entropy which follows information theoretical requirements. Based on these studies and the implementation, the caller can assume that one bit of data extracted from the CPU Jitter Random Number Generator holds one bit of entropy. The CPU Jitter Random Number Generator provides a decentralized source of entropy, i.e. every caller can operate on a private state of the entropy pool. The RNG does not have any dependencies on any other service in the kernel. The RNG only needs a high-resolution time stamp. Further design details, the cryptographic assessment and large array of test results are documented at http://www.chronox.de/jent.html.

* | crypto: echainiv - Add encrypted chain IV generatorHerbert Xu2015-05-221-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a new AEAD IV generator echainiv. It is intended to replace the existing skcipher IV generator eseqiv. If the underlying AEAD algorithm is using the old AEAD interface, then echainiv will simply use its IV generator. Otherwise, echainiv will encrypt a counter just like eseqiv but it'll first xor it against a previously stored IV similar to chainiv. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* | crypto: seqiv - Add support for new AEAD interfaceHerbert Xu2015-05-221-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch converts the seqiv IV generator to work with the new AEAD interface where IV generators are just normal AEAD algorithms. Full backwards compatibility is paramount at this point since no users have yet switched over to the new interface. Nor can they switch to the new interface until IV generation is fully supported by it. So this means we are adding two versions of seqiv alongside the existing one. The first one is the one that will be used when the underlying AEAD algorithm has switched over to the new AEAD interface. The second one handles the current case where the underlying AEAD algorithm still uses the old interface. Both versions export themselves through the new AEAD interface.

* | crypto: 842 - change 842 alg to use softwareDan Streetman2015-05-111-4/+3
|/ | | | | | | | | | | | | | | | | | | | | | Change the crypto 842 compression alg to use the software 842 compression and decompression library. Add the crypto driver_name as "842-generic". Remove the fallback to LZO compression. Previously, this crypto compression alg attemped 842 compression using PowerPC hardware, and fell back to LZO compression and decompression if the 842 PowerPC hardware was unavailable or failed. This should not fall back to any other compression method, however; users of this crypto compression alg can fallback if desired, and transparent fallback tricks callers into thinking they are getting 842 compression when they actually get LZO compression - the failure of the 842 hardware should not be transparent to the caller. The crypto compression alg for a hardware device also should not be located in crypto/ so this is now a software-only implementation that uses the 842 software compression/decompression library.

The idea of the multi-buffer algorihtm is to put data streams from multiple jobs in a wide (AVX2) register and then take advantage of SIMD instructions to do crypto computation on several buffers simultaneously. The multi-buffer crypto daemon is also responsbile for flushing the remaining buffers to complete the computation if no new buffers arrive for a while.
