CC3120: Are 4096 bit RSA keys supported for authentication in an Enterprise network?

What variable are you getting the value 0x41336 from?

Sorry, should have been more clear. When we tried a 4096 bit RSA key, the slcb_DeviceFatalErrorEvtHdlr() gets called with the following values:

pSlDeviceFatal->Id = SL_DEVICE_EVENT_FATAL_DEVICE_ABORT
pSlDeviceFatal->Data.DeviceAssert.Code = 0x41336
pSlDeviceFatal->Data.DeviceAssert.Value = 0

Hello,

Any further info on this? The fundamental question we have is whether the CC3120 supports 4096 bit RSA keys during connection to an Enterprise network. If so, then the question is what could be causing the fatal errors mentioned above.

Thanks much!

Hi Ed,

I believe this is the case, but I will double check. What host processor are you using? I wonder if the timeout on the API call response itself is too short, since this is something to be controlled per platform when not using CC3220

Hi Aaron,

Thank you for the reply. We are using a MSP430F5253 as the host, and we are not implementing the timestamp feature, so every API call has an infinite timeout. So I think the error I'm getting is a valid fatal error from the CC3120.

I see what you mean. I'll look into this and get back to you.

Hi Shlomi,

I'm referring to this document: www.ti.com/.../swru455

While the crypto algorithm information is contained in the section on secure sockets, I was hoping it applied to enterprise connections also. Is there similar information available for enterprise connections? I apologize if it exists somewhere, but I don't recall seeing it.

In any event, thank you for the answer!

Hello Ed,

I do not see similar info under the WLAN section.

It might be valuable to add it for the complete picture.

Thanks,

Shlomi
