Features/VirtioCrypto: Difference between revisions

Revision as of 02:05, 13 September 2016

The virtio crypto device is a virtual crypto device, and is a kind of virtual hardware accelerator for virtual machines. The encryption and decryption requests are placed in the data queue, and handled by the real crypto accelerators finally. The second queue is the control queue, which is used to create or destroy sessions for symmetric algorithms, and control some advanced features in the future. The virtio crypto device can provide seven crypto services: CIPHER, MAC, HASH, AEAD, KDF, ASYM, PRIMITIVE.

Code

Virtio-crypto specification: Gonglei's virtio.git
Virtio-crypto linux driver: Gonglei's virtio-crypto-linux-driver.git
QEMU: Gonglei's qemu.git
Cryptodev-linux: Cryptodev-linux's website Cryptodev-linux is implemented as a standalone module that requires no dependencies other than a stock linux kernel.

Quickstart

Host:

Step 1: Use the cryptodev-linux as the client, the cryptodev.ko should be insert on the host.

Cryptodev:

 $ git clone https://github.com/cryptodev-linux/cryptodev-linux.git
 $ cd cryptodev-linux
 $ make; make install

Step 2: Build qemu with cryptodev-linux support

QEMU:

 $ git clone -b virtio-crypto https://github.com/gongleiarei/qemu
 $ cd qemu
 $ ./configure --target-list=x86_64-softmmu
 $ make

Guest:

Step 1: Build and install virtio-crypto linux driver.

 $ git clone https://github.com/gongleiarei/virtio-crypto-linux-driver.git
 $ cd virtio-crypto-linux-driver
 $ make;make install

Step 2: use cryptodev-linux test the crypto functions

Testing

Use the cryptodev-linux module to test the crypto functions in the guest.

$ git clone https://github.com/gongleiarei/virtio-crypto-linux-driver.git
$ cd virtio-crypto-linux-driver
$ make
&
