Table 17-18 Lookup AATV Attributes for EAP-AKA (continued)
DescriptionAttribute
An optional string attribute that contains the name of the AKA algorithm
used to authenticate the user. This attribute is optional if a default value is
configured for the realm. The value is case-sensitive.
AKA-Algorithm
A fixed-length binary string (octets) attribute that contains the 48-bit sequence
number, which is used to authenticate the user.
AKA-Sequence-Number
An optional fixed-length binary string (octets) attribute that contains a 16-bit
value. The value indicates whether the AKA-Sequence-Number is used for
AKA-Mode
a Circuit Switched or Packet Switched authentication. This attribute is optional
if a default value is configured for the realm.
AND
Optional Reply item, such as, Session-Timeout and Idle-Timeout.
Other reply attributes
Lookup AATV Functionality and Return Events
The Pseudonym Lookup AATV attempts to retrieve the Real-Username from its
database.
• If the information is found, the Lookup AATV updates the cur_request list of
the authreq with the specified output, and a RETRIEVE_SUCCESS message is
returned.
• If the information is not available, a RETRIEVE_ERROR message is returned.
• The Lookup AATV can check if the Pseudonym-Username has expired based on
the Pseudonym-Expiration-Time. If the Pseudonym-Username has expired,
a RETRIEVE_ERROR message is returned, and the cur_request list of the
authreq is not updated. If the AATV does not check for an expired entry, the
Pseudonym-Expiration-Time is returned. Subsequently, the HP-UX AAA
Server checks for the expiration.
The Pseudonym-Expiration-Time values represent the following:
— Last-Used-Pseudonym-Expiration-Time -- If the Pseudonym-Username
matches the Last-Used-Pseudonym-Username
— Last-Assigned-Pseudonym-Expiration-Time -- If the
Pseudonym-Username matches the Last-Assigned-Pseudonym-Username
• A successful mapping can also return user credentials and general reply-items. If
the user credentials are returned, these credentials are appended to the
cur_request list of the authreq, as specified.
Generating Authentication Vectors Using A3, A8, and AKA Algorithms
If authentication vectors are not retrieved from a datastore or supplied by an external
AuC, they must be generated using A3 and A8 algorithms for EAP-SIM or the AKA
algorithm for EAP-AKA.
