Example of Context in GCM Encryption
For illustrative purposes we consider the case of a GCM encrypt operation that generates the final MAC
tag, where the whole message is small enough to be processed with one descriptor. AESU mode register
bits 56-63 (ECM, AUX, CM, and ED) should be set to 10_100_01_1. Only context registers 11–12 must

partially computed GHASH(H, AAD, ciphertext), where the last GHASH iteration is not
computed.
In the case of GCM with ICV, the final MAC tag written here as the result of GCM processing is
truncated to 8, 12, or 16 (no truncation) bytes as defined in ICV size register. Note that any size
from 1 to 16 bytes can be specified in ICV size register but any value other than 8 or 12
automatically defaults to 16 bytes.
Registers 3–4 contain the received MAC tag, in case of inbound processing using GCM with ICV.
This can be a 8, 12 or 16-byte block as specified by the ICV size register.
Registers 5–6 contain the counter value Y
continue processing a message. Note that the same value read when saving context should be
written to these registers when restoring the context, since it is automatically incremented after
every processed block.
In the case of GCM-GHASH, these registers are not used.
Register 7 contains the total length of the additional authenticated data (AAD) in bits. This is the
total AAD length irrespective of whether AAD is split in multiple descriptors. It is required when
AUX1=1 and the current descriptor processes the last segment of AAD or text data. It is also
required if the whole message is already processed and the current descriptor only computes the
final MAC tag.
Register 8 contains the total length of the plaintext/ciphertext or IV in bits. This is required only
when AUX1=1 (see
then total IV length should be provided; otherwise, the total length of text data should be provided.
Registers 9–10 contain the initial counter value Y
processing and needs to be provided only if the message is split into multiple descriptors and for
those descriptors that come after IV processing is complete. Otherwise, the value provided here is
ignored and overwritten with computed Y
In case of GCM-GHASH cipher mode setting, the constant H from GHASH(H, AAD, ciphertext)
should be provided in these registers. Note that in the general case this may not be to be equal to
E(K, {0}
Register 11 contains the length (in bits) of the AAD part processed in the current descriptor. If the
current descriptor does not process AAD, then the register should be zero. If AAD is not split into
multiple descriptors, then this field should contain the total AAD length. The value written here
should be divisible by 128 for all AAD segments except for the last one, which can be any number
of bits. Note, however, that the actual AAD stream supplied to the AES engine through the FIFOs
has to be zero-padded to an integral number of 16-byte blocks.
Register 12 contains the length (in bits) of the IV part processed in the current descriptor. Similar
remarks apply for IV in register 12 as for AAD in register 11.
In case of GCM-GHASH, this register is not used.
