# The WiMAX module currently takes no configuration.
|
||
|
|
#
|
||
|
|
# It should be listed in the "authorize" and "preacct" sections.
|
||
|
|
# This enables the module to fix the horrible binary version
|
||
|
|
# of Calling-Station-Id to the normal format, as specified in
|
||
|
|
# RFC 3580, Section 3.21.
|

|
|
#
|

|
|
# In order to calculate the various WiMAX keys, the module should
|
||
|
|
# be listed in the "post-auth" section. If EAP authentication
|
||
|
|
# has been used, AND the EAP method derives MSK and EMSK, then
|
||
|
|
# the various WiMAX keys can be calculated.

|
|

|

|
|
# Some useful things to remember:
|
||
|
|
#
|
||
|
|
# WiMAX-MSK = EAP MSK, but is 64 octets.
|

|
|
#

# MIP-RK = MIP-RK-1 | MIP-RK-2
|
||
|
|
#

|
|
# MIP-SPI = first 4 octets of HMAC-SHA256(MIP-RK, "SPI CMIP PMIP")
|
