Security Engine (SEC) 2.1
12.1
The position of the SEC 2.1 (henceforth referred to as SEC) in the MPC8544E architecture is shown in
Figure
movement bottleneck normally associated with slave-only cores. The host processor accesses the SEC
through its device drivers using DDR system memory for data storage. The SEC resides in the peripheral
memory map of the processor; therefore, when an application requires cryptographic functions, it simply
creates descriptors for the SEC which define the cryptographic function to be performed and the location
of the data. The SEC’s bus-mastering capability permits the host processor to set up a channel with a few
short register writes, leaving the SEC to perform reads and writes on system memory to complete the
required task.

AFEU—ARC Four execution unit
— Implements a stream cipher compatible with the RC4 algorithm
— 40- to 128-bit programmable key
KEU—Kasumi execution unit
— Implements the Kasumi cipher
— Performs F8 encryption and F9 integrity checking as required for 3GPP
— Additionally performs A5/3 and GEA-3 modes as used in GSM, EDGE, and GPRS
MDEU—Message digest execution unit
— SHA with 160-bit, 224-bit, or 256-bit message digest
— MD5 with 128-bit message digest
— HMAC with either algorithm
RNG—Random number generator
XOR parity generation accelerator for RAID applications
Four crypto-channels, each supporting a queue of commands (descriptor pointers)
— Dynamic assignment of crypto-execution units via an integrated controller
— 256-byte buffer FIFOs on data input and output paths of each execution unit, with flow control
Master/slave logic, with DMA capability
— 36-bit address/64-bit data
— Master interface allows multiple pipelined requests
— DMA blocks can be on any byte boundary
Scatter/gather capability
— Gather capability enables the SEC 2.1 to concatenate multiple segments of memory when
— Similarly, scatter capability enables SEC 2.1 to write to multiple segments of memory when
