PDC / PMU Authentication

Nov 6, 2011 at 3:23 PM

All - I have been reading the IEEE C37.118 Spec and I am interested in researching the security aspects of the protocol.  I did not see any information concerning security authentication between the PMU and the PDC.  Does anyone know specifically which specification defines the handshaking between the PDC and PMU when authentication is performed for the devices?

Yours question is very good!

At this time, there is no specific requirement for PMU to PDC communications security. The IEEE C37.118 specification does not require specific security or authentication.

The NASPI PDC Requirements Jan 2011 draft document, section 5.4 states:

"A production-grade synchrophasor system that is considered to be a critical cyber asset will be required to meet the security requirements of NERC CIP standards."

Thanks - I will take a look at the sites.  Your explanation really clears up my confusion - I was scouring IEEE, and ACM trying to find security standards for C37.118.  The closest thing I could find is a vague reference to DNPv3.  

Thanks Again.
