support HLS Authentication for C++

Hi
Where is the relevant code? How to enable HLS at server side
for example HLS 5 - Galois Message Authentication Code (GMAC)

Hello Mikko Kurunsaari,

Using the latest version from today

I am trying work with DLMS_AUTHENTICATION_HIGH_GMAC
Got a coredump , see below
(gdb) p block->c3 >> 24
$1 = 1099511627708
AES is 255 array, so it crashed.
I've tried to change code to r0 ^= Shift((AES[block->c3 >> 24 ) & 0xFF], 8);
but then server side return InvalidConnection.

(gdb) r
Starting program: /home/micgur01/work/cleanDLMS/Gurux.DLMS.cpp/GuruxDLMSClientExample/bin/gurux.dlms.client.bin
InitializeConnection

Program received signal SIGSEGV, Segmentation fault.

---Type <return> to continue, or q <return> to quit---

By the way, only DLMS_AUTHENTICATION_LOW is working
others can not connect at all, and DLMS_AUTHENTICATION_HIGH_GMAC results coredump.
Could you please help?
Maybe need more settings to change, rather then authentication option?

Thanks,
Michael

Hi

Gurux.DLMS.cpp example as is, yep CGXDLMSSecureClient
CGXDLMSSecureClient cl(useLogicalNameReferencing, clientAddress, serverAddress, authentication, password, interfaceType);

Linux Ubuntu(64 bit)

BR,

Hi

Just check it on raspberry pi3 , Ubuntu Mate 32bit ( both client and server).
It looks ok, using GMAC - no coredump, print all info
Looks like 32/64 bit problem

it still problematic using server and client with different architecture, one 32 and other 64.

By the way , other HLS did not even start any object prints.

Thanks,
Michael
