From the EMSK, the CMI

48、AA-SPI3gpp2”) The MN-AAA-SPI indicates the specific security association between the AT and HAAA and algorithm used in computation of the MN-AAA Authentication Extension. If the value of this computed MN-AAA-SPI is equal to or smaller than 255, then an integer value of 256 shall be added to the comp
49、uted value. If the MN-AAA-SPI collides with another SPI value already allocated for the AT, then the SPI value shall be monotonically incremented until the SPI value has no collision for that AT. From the CMIP4-MN-RK, the MN-HA key and its associated MN-HA-SPI shall be derived as follows: MN-HA Key = HMAC-SHA-256 (CMIP4-MN-RK, “MN-HA3gpp2”, HA IP Address) MN-HA-SPI = HMAC-SHA-256 (MN-HA key, “3GPP2-MN-HA-SPI3gpp2”) The MN-HA-SPI indicates the specific security association between the AT and HA and algorithm used in computation of the
