Why is ccm_soft used in the Mesh SDK?

Marius Heil

Hi,

I am wondering why the ccm library uses the software aes encryption. Is there anything wrong with the hardware encryption so that it should not be used?

    Sorry. Looks like I was wrong. That happened after long hours of looking through encryption papers and attack methods and I must have been exhausted ;-) Maybe I will try to use the nordic ccm implementation, I haven't yet found a good one. i need one that keeps its internal state when called more than once, because most that I've found will only encrypt a stream if the stream is given in one call.
