Security Engine (SEC) 2.1
12.4.7.10 KEU IV 1 Register (KEUIV1)
The KEUIV1 register is a general purpose IV register used during the initialization phase of the F8
algorithms for 3GPP, GSM A5/3, EDGE A5/3, GPRS GEA3 and also for the F9 algorithm for 3GPP. The
appropriate value as defined by the standards for each algorithm must be written before a new message is
started. After the initialization phase has been completed, KEUIV1 register is no longer used for the
remainder of F8 or F9 processing. However, if 3GPP F9, is selected, because the KEUIV1 register contains
the direction bit as defined by the 3GPP standard, the KEUIV1 register must be written back during
context switches, to complete the generation of the 3GPP MAC.
Address KEU 0x3_E100
12.4.7.11 KEU ICV_In Register (KEUICV)
If ICV checking is required, then the value to be compared with the computed F9 MAC value must be
written to the ICV_In register before data size is written.
