KNX Data Secure
|
||
|
|
===============
|
||
|
|
|
||
|
|
Implementation Notes
|
||
|
|
--------------------
|
||
|
|
* Implementation based on application note AN158 v07 KNX Data Security
|
||
|
|
* AES-128 is implemented in software, no hardware acceleration used currently
|
||
|
|
* Secure device setup with ETS-5.7.x tested and working
|
||
|
|
* Secure group communication needs more testing
|
||
|
|
* Support for FDSK generation
|
||
|
|
* Support for P2P mode prepared
|
||
|
|
* No support for LTE-mode[T_Data_Tag_Group] (zone key table is already there) currently
|
||
|
|
* No support roles (and no plan to implement this in the near future)
|
||
|
|
|
||
|
|
ToDo:
|
||
|
|
-----
|
||
|
|
* Add support for AN192 v04 Coupler security extensions (a.k.a. Secure Proxy which translates between unsecured and secured devices)
|
||
|
|
* Handle S-A_Sync Service when initially the last valid sequence nummer is not known during runtime, i.e. group communication
|
||
|
|
* handle MasterReset according to spec. for security interface object
|
||
|
|
|
||
|
|
Development environment
|
||
|
|
-----------------------
|
||
|
|
* see linux example on how to generate the FDSK string which needs to be entered in the ETS
|
||
|
|
* use BAU57B0, but fake the mask by setting _deviceObj.maskVersion(0x07B0). This "emulates" a TP1 device which is reachable over an IP router
|
||
|
|
* To generate a KNX ETS product database with support for KNX Data Secure, use the latest version of the CreateKnxProd tool which supports schema version 20.
