</h1>
<p class="class_5">
<font style="font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;">Security mechanisms for ITS consist of a number of parts. An important part for interoperability is a common format for data elements being transferred between ITS stations for security purposes.</font>

<p class="class_5">
<font style="font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;">The present document intends to provide such a format definition. A special focus is to include as much as possible from existing standards. At the same time, the major goal is simplicity and extensibility of data structures.</font>

An example for a reason to increase the
<font style="font-family: Courier New;">
protocol_version
<font style="font-family: Times New Roman;">

<font style="font-family: Courier New;">
unknown
<font style="font-family: Times New Roman;">
case in clause 5.4. This header field can be ignored by old implementations, if the syntax is kept identical and the versions are compatible. Hence, the

Usage of ITS-AID and SSPs

</h8>
<p class="class_5">
<font style="font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;">An incoming secured message should only be accepted by the receiver if the payload of the secured message is consistent with the ITS-AID and SSP in the certificate. This consistency should be checked in two ways:</font>

<font style="font-family: Times New Roman; font-size: 10pt; font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;">
Within the security processing, the ITS-AID in the certificate can be checked for consistency with the
<font style="font-family: Courier New;">
its_aid
<font style="font-family: Times New Roman;">field in the SecuredMessage format.</font>

<font style="font-family: Times New Roman; font-size: 10pt; font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;">At the point at which the data is processed (which may be in the receiving facilities layer or in the receiving application layer), the data can be checked for consistency with the ITS-AID and the SSP from the certificate. Architecturally, this check is carried out by the processing entity that processes the data payload of the SecuredMessage, not by the security processing services. This is because the security processing services cannot and should not be expected to be able to parse the data of all possible different applications and facilities. Thus, a full definition of a data exchange for applications or facilities that use signed messages should include a specification of the ITS-AID, a specification of the SSP, and a definition of what it means for the data itself to be consistent with the ITS-AID and SSP.</font>

If they are, the group reserves an ITS-AID and defines an SSP.</font>

<font style="font-family: Times New Roman; font-size: 10pt; font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;">On the receiving side, the data processing entity (which may be an application or the facilities layer) uses the ITS-AID and SSP from the certificate to check that the data is consistent with those permissions. This means that the ITS-AID and SSP should be made available to the data processing entity, for example by passing them across an interface from the security processing, or by passing the entire certificate and letting the data processing entity extract the ITS-AID and SSP from the certificate, or by some other means.</font>

NOTE 1:
<img border="0" height="1" src="data:image/gif;base64,R0lGODlhAQABAAD/ACwAAAAAAQABAAACADs%3D" width="18"/>
The ITS-AID and SSP are contained in the certificate, which is cryptographically authenticated and authorized by the Authorization Authority. Because of this cryptographic authentication, it is impossible for the certificate holder to change their permissions without causing cryptographic authentication to fail.

NOTE 2:
<img border="0" height="1" src="data:image/gif;base64,R0lGODlhAQABAAD/ACwAAAAAAQABAAACADs%3D" width="18"/>
The ETSI TS 103 097 certificate format allows a certificate to contain multiple (ITS-AID, SSP) pairs. In this case, the receiving side processing is expected to know which ITS-AID is to be used in conjunction with an incoming message.

<p class="class_5">
<font style="font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;">One way to make the concept of SSP future proof is to add the version number of the corresponding facility to the SSP.</font>
</p>
<p class="class_5">
<font style="font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;">The interpretation of the SSP is specific for each facility. One possible way to implement it is to use a bit map to define which permissions a sender is authorized to use.</font>
</p>
<p class="class_5">
<font style="font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;">The bit value "1" then means that the sender is authorized to use the corresponding feature and consequently the bit value "0" means that the sender is not authorized to use it.</font>
