hi,
I would like to run a 100Mb/s tor exit node, but I have issues wrt power consumption.
reading http://ortizaudio.blogspot.fr/2011/10/using-dreamplugs-crypto-chip.html it seems dreamplugs has *fast* aes-128-ecb.
Does anyone have any experience running a node based on cheap crypto chip (dreamplug, marvell 88F6282, sheeva-core, padlock, ...) ? What performance can I expect out of these ?
regards, sv

I once meassured the performance of the padlock crypto chip on a VIA Esther C7 1500 MHz processor. Result: AES-128 cbc with padlock is about 14 times faster compared to the C7 with padlock disabled.

Unfortunately AES is not the primary CPU consumer on Tor nodes right now; we spend a lot more time doing bignum computation for TAP circuits. Crypto accelerators don't work very well for bignums.
It's not a perfect equivalence, but "openssl speed rsa" should give a reasonable estimate of how well your chip will do for TAP circuit creation. Here's a dual-core Westmere at 2.1 GHz (should be fairly close to a modern Xeon core):
sign verify sign/s verify/s rsa 512 bits 0.000105s 0.000007s 9548.7 137778.7 rsa 1024 bits 0.000340s 0.000021s 2941.1 48539.0 rsa 2048 bits 0.002205s 0.000070s 453.4 14362.8 rsa 4096 bits 0.016398s 0.000260s 61.0 3840.3
A single Xeon core can currently handle most of a 100 Mbps exit node's traffic, so you should look for a dual-core chip that delivers at least 1500 sign/s on rsa-1024. Unfortunately I doubt there are any ARM chips that can compete.

First step is, run "openssl speed rsa" and post the output to the list. While you're at it you may as well post the AES and SHA results as well. Heck, just run the whole "openssl speed" test (should take less than 20 minutes) and post the whole thing. :)
Also details on what CPU/RAM it has, and information about the kernel and OpenSSL package you are testing, would be useful. "dmesg" output and the contents of /proc/cpuinfo may be helpful.

The pi doesn't have any as I'm aware of, I was looking into any and all small boards that posses the marvell kirkwood chipset which is supported by cryptodev module which openssl can be compiled to utilize. The cheapest one seems to be the v2 pogoplug, which can be had for as cheap as $20 USD off amazon.
here's some good info: http://www.altechnative.net/2011/05/22/hardware-accelerated-ssl-on-marvell-k...
Here's a brief overview of what I've tried to get working on my debian squeeze pogoplug. http://forum.doozan.com/read.php?2,9619
Here's a good listing of common plug boards and which processors they contain, including the pi: http://archlinuxarm.org/platforms
Perhaps if enough are interested we could form a small group to work on this again. mail me directly if interested.
The output from the pogo 'openssl speed rsa' is as follows (keep in mind this is WITHOUT cryptodev support enabled). If someone points me to the appropriate place on the wiki I'll be happy to fill in the required info.

The RasPi is nice but it's also not terribly powerful. It definitely has its limits. For example, I found out the hard way last weekend that trying to run an Etherpad-Lite on a RasPi is a great way to run one into the ground...

I have a RasPi Model B Rev 2 running etherpad-lite and a Tor-Relay. Slow as shit, but it works. :-)
Happily, it DOES appear that there may be some hope for the Allwinner A20 based Cubieboard 2 (I haven't checked for the original Cubieboard yet):
"The Security System (SS) is one encrypt/ decrypt function accelerator that is suitable for a variety of applications. It supports both encryption and decryption. Several modes are supported by the SS module.
It features:
AES, DES, 3DES, SHA-1, MD5 are supported by this system ECB, CBC, CNT modes for AES/DES/3DES 128-bit, 192-bit and 256-bit key size for AES 160-bit hardware PRNG with 192-bit seed 32-word RX FIFO and 32-word TX FIFO for high speed application Support CPU mode and DMA mode Interrupt support"
http://dl.linux-sunxi.org/A20/A20%20User%20Manual%202013-03-22.pdf
So, it may be a little help, anyway.
The Cubieboard 2 is great for small Tor relays - it'd definitely be more capable than a Raspberry Pi model B as it has double the RAM and 2 more powerful cores with ARMv7 instead of ARMv6.
It's also almost double the price (for considerably more than double the computer), but I don't expect that to last long.
