SAM4CP [DATASHEET]

43051E–ATPL–08/14

summarizes the different cases.

Depending on the mode, there are other ways of clearing the DATRDY flag. See

“AES Interrupt Status

In PDC mode, reading the AES_ODATARx before the last data transfer may lead to unpredictable results.

41.4.5 Galois Counter Mode (GCM)

41.4.5.1 Description

GCM comprises the AES engine in CTR mode along with a universal hash function (GHASH engine) that is defined over

a binary Galois field to produce a message authentication tag (the AES CTR engine and the GHASH engine are depicted

Figure 41-5, ”GCM Block Diagram”

The GHASH engine processes data packets after the AES operation. GCM provides assurance of the confidentiality of

data through the AES Counter mode of operation for encryption. Authenticity of the confidential data is assured through

the GHASH engine. GCM can also provide assurance of data that is not encrypted. Refer to the

NIST Special Publication

800-38D Recommendation

for more complete information.

GCM can be used with or without the PDC master. Messages may be processed as a single complete packet of data or

they may be broken into multiple packets of data over time.

GCM processing is computed on 128-bit input data fields. There is no support for unaligned data. The AES key length

can be whatever length is supported by the AES module.

The recommended programming procedure when using PDC is described in

Section 41.4.5.3
