Hello,

Does "source node authentication" mechanism is implemented in Z-stack? or if it is not implemented by default then does TI solution support additional implementation of "source node authentication" mechanism ?

Even I don't know what is the meaning of this.

I found this here -

Defense Strategies And Security Best Practice Recommendations

A few of the security practices which are recommended while implementing a ZigBee WPAN networks are:

Source node authentication should be implemented across all the nodes if the ZigBee vendor supports it, this will help in the identification of the transmitting node.

Dhanraj,

This is talking about Link Keys assigned by the Trust Center, also see page 14 of www.energy.gov/.../Securing_ZigBee_Wireless_Networks.pdf

This is basically "High Security" mode from R20 which now comes standard in R21, which is supported by Z-Stack: http://processors.wiki.ti.com/index.php/What%27s_New_in_ZigBee_3.0

Basically its similar to install code technique. correct me if i am wrong.

Not the same as install codes, which are optional to enhance security between the trust center and joining device for joining the network. Once in the network a link key is assigned by the Trust Center and established for two nodes so that they can exchange information privately.
