SGAC & CSWG

Review of PAP11 Standards

sgac comments
SGAC Comments

SAE J2847-1

The term premise is incorrectly used in several places in the document.  The correct term is premises. 

RESPONSE: Editorial fix will be made this next revision of j2847

The definition of “Interoperability” is weak.  It would be more appropriate to use the definition developed by the GWAC. 

RESPONSE: proposed definition:  "The condition where components of a system, relative to each other, are able to work together to perform the intended operation of the total system. Information interoperability is the capability of two or more networks, systems, devices, applications, or components to share and readily use information securely and effectively with little or no inconvenience for the user.”

SGIP Grid-Interop 2010, Chicago, Ill

sgac comments1
SAE J2847-1 (cont)

The standard seems to assume an architecture with all communications from the vehicle to the grid flowing through the electric meter. The standard would be better constructed were it to clearly separate the syntactic and semantic communications from the physical communications path.

RESPONSE:  Section 4.4 and all sequence diagrams will be removed from j2847 (j2847 will focus only on the messages).  

SGAC Comments

SGIP Grid-Interop 2010, Chicago, Ill

sgac comments2
SAE J2836-1

Same misuse of the work premise when the work premises should be used.  

RESPONSE: Editorial fix will be made this revision

Same comment regarding definition of interoperability on page 10.  

RESPONSE:  Same interoperability definition will be used as in J2847-1

SAE J1772™      No Comments

SGAC Comments

SGIP Grid-Interop 2010, Chicago, Ill

cswg comments
SAE J2847-1

Remove all references to cybersecurity and develop a separate, corresponding cyber-security document. Because there are many missing cybersecurity requirements, it is recommended that Section 4.3.1.2 and all references to cybersecurity be removed from this document and that another document or documents be developed to address cybersecurity for these information exchanges.

RESPONSE: Change will be made this revision.  New document has been created (SAE J2931)

CSWG Comments

SGIP Grid-Interop 2010, Chicago, Ill

csqg comments
SAE J2847-1

Remove the mapping to SEP2.0  in order to separate semantic standards from their mappings to different protocols that will have different cybersecurity technologies. Because the SEP 2.0 protocol is not yet defined, may not be used by utility operational systems, and because other protocols could be used to support the messages defined in Section 4.3 in different architectures with different cyber-security technologies, it is recommended that Section 4.4 be removed in order to keep the semantic standards separate from the various protocols which could transport those messages. 

RESPONSE: Change will be made this revision.  New document has been created: SAE J2931

CSQG Comments

SGIP Grid-Interop 2010, Chicago, Ill

cswg comments1
SAE J2847-1

Ensure consistency with the results of other PAPs. Role of the Internet Protocol Suite (IPS) in the Smart Grid, developed as an output of PAP 01,[1] does not include EAP (RFC 3748), but instead identifies EAP-TLS (RFC 5216), which in turn references EAP (RFC 3748). Consistency between PAP 1 and PAP 11 would be a good goal, but is not absolutely required. 

RESPONSE: will work to coordinate between PAPs. (refer to IETF IPS working group proposed this week during GB meeting)

CSWG Comments

SGIP Grid-Interop 2010, Chicago, Ill

cswg comments2
SAE 2846-1

Reference the FIPS-approved list of cryptography suites. The acceptable cyber cryptography suites are listed, which may limit future applicability. It is suggested that the document reference the Federal Information Processing Standard (FIPS)-approved list of cryptography suites.  

RESPONSE:  Will bring to SAE - use FIPS as general standard

References to unfinalized IETF RFCs should be removed. The reference to IETF RFC 4492 should be removed until the IETF finalizes the RFC.  

RESPONSE:  Yes, will review and make changes as necessary 

CSWG Comments

SGIP Grid-Interop 2010, Chicago, Ill

cswg comments3
SAE J2836

It is recommended that this standard be accepted as is, but that additional cybersecurity Use Cases be developed during the next V2G PAP and/or DEWG efforts.  

RESPONSE: A subgroup will be formed within the V2G DEWG to develop v2g cybersecurity use cases

The normative and informative reference document list within SAE J2836/1 should also be reviewed to determine if any cybersecurity requirements in those documents need to be updated or enhanced.  

RESPONSE:  SAE will coordinate with CSWG 

CSWG Comments

SGIP Grid-Interop 2010, Chicago, Ill

cswg comments4
SAE J1772

If PLC, wireless, or other potentially radiating technology is used for the communications, the traffic between the PEV and the EVSE should be encrypted.

RESPONSE:  it's going to be covered in other standards. security will be an important issue.

The normative and informative reference document list within SAE J1772-TM should be reviewed to determine if any cybersecurity requirements in those documents need to be updated or enhanced.  

RESPONSE: SAE will coordinate with CSWG
