Dear Developers,

We are working on IoTivity Secured application. We have following doubts 
regarding security in IoTivity for which we require guidance.


1. The provisioning client and server (Justworks, Random PIN) given in 
(<Iotivity out Root>/../../csdk/../provisioning/samples/) works properly when I 
run two servers simultaneously.


While provisioning the owned devices, Provisioning client asks for Device ID 
and Subject ID. Is it required to run two servers for provisioning the servers 
for permissions?


2. I couldn't able to find any asymmetric key transfer type examples in the 
same directory, Where the asymmetric type ownership transfer example placed?.


If it is not supported yet, Is there plan to release with next version of 
IoTivity?


3. As per the trailing mail CK Manager is removed and mbedTLS is implemented, 
Is it only for SSL/TLS, RNG implementation or total TinyDTLS is replaced by 
mbedTLS?


4. If mbedTLS is future of IoTivity Security, then can we use mbedTLS 
certificate generation to implement security in Server?


5. I could find rootca.crt file in Security folder is it for embedTLS 
implementation?, If so, in practical application is it required to place 
generated crt file in with server?

Hi Shreyas,

Please note ckm manager was removed in 
https://gerrit.iotivity.org/gerrit/#/c/12029/, it was replaced by mbedTLS 
library.

@randeep: can you guide how to use certificate mode in the security code.

Kind Regards
Habib

Dear Developers,


  I tried building IoTivity (SECURED=1) by all ways shown on below llink:

1.scons SECURED=1
2.scons SECURED =1 resource
3../auto_build.sh linux_secured

https://openconnectivity.org/wp-content/uploads/2016/01/Habib-Virji.pdf

I am not able to find the folder ck_manager in 
<iotivity>/out/linux/x86_64/release/resource/csdk/securtiy/provisioning/
and in below path i didn't find samples in ck_manager:
<iotivity>/out/linux/x86_64/debug/resource/csdk/securtiy/provisioning/

Innovation is change that unlocks new value..!!

Thanks & Regards,
