Hi Rafa, Hi Malisa, Hi Pablo, Hi all, earlier this year I presented some performance results to the LWIG working group and the details can be found at: https://www.ietf.org/proceedings/92/slides/slides-92-lwig-3.pdf
The idea of my presentation at the Dallas IETF meeting was to get some others to enhance the performance investigations to provide others a better idea of what they can expect when using state-of-the-art crypto in IETF protocols as part of their IoT platform. The results would be summarized in an IETF draft, such as in the TLS minimal draft (see https://tools.ietf.org/wg/lwig/draft-ietf-lwig-tls-minimal/). Subsequently, I also worked with my co-worker Manuel on a submission to the NIST lightweight cryptography workshop where we summarized our work. Here is the link to the workshop: http://www.nist.gov/itl/csd/ct/lwc_workshop2015.cfm While it was difficult to find someone who is interested in doing some performance analysis I luckily found some folks, which are on CC, who said that they might be able to contribute some thoughts. Malisa mentioned in the ACE working group meeting that he has done some current consumption measurements. Rafa has done some ECC measurements previously and those might give additional data points. Pablo has done performance measurements and was interested in spending additional time on that subject. We had the chance to chat at the Prague IETF meeting. Here is what I believe we need: * Verification of the existing results. * More data from other crypto libraries (or even DTLS/TLS stacks). * Tests run on other hardware platforms (such as the Cortex M7). * Tests beyond performance, such as RAM usage, flash size, etc. * Tests that focus on other algorithms. If would be great if folks could help with that or provide pointers if they have already done some work. If you are interested please drop me/us a message. I am happy to talk about what we should /shouldn't investigate as part of this exercise. I am convinced that this data is useful for many engineers and researchers. While most folks immediately want to create some new algorithms I believe it is good to know how fast the currently available algorithms are on modern IoT hardware. Ciao Hannes
