Summary

0006890: 3d profile messages should have its-aid anyway

Description

Mark Etzel [metzel@securityinnovation.com]:
On yesterday's call you mentioned there had been some concern about the
Generic security profile for other signed messages and ITS-AIDs and
asked if there were still concerns. Since I was a couple minutes late,
I was muted and couldn't respond, but I'd like to address that now.

When we in C2CCC WG Sec made changes in TS 103 097 to remove
message_type and security_profile in favor of adding ITS-AID, I had
assumed that the change applied to all messages, and that the lack of
ITS-AID in the Generic profile was simply an omission. It is my
understanding that certificates have permissions to sign particular
types of messages; this is accomplished by ITS-AIDs. The list of
ITS-AIDs in a certificate permits that certificate to sign any message
containing one of those ITS-AIDs. I don't know what certificate is
permitted to sign a message with no ITS-AID. And, we identify which
certificate to use based on the ITS-AID in the message.

William has emailed WG5 about this as well, but we would strongly
suggest that the intent was to include an ITS-AID in all messages.

Best regards,
Mark
