Security Engine (SEC) 3.0
This chapter describes the functionality of Freescale’s integrated security engine (SEC 3.0). It addresses
the following topics:
The SEC 3.0 is designed to off-load computationally intensive security functions, such as key generation
and exchange, authentication, and bulk encryption from the processor core of the SoC. It is optimized to
process all cryptographic algorithms associated with IPsec, IKE, SSL/TLS, iSCSI, SRTP, 802.11i,
WiMAX, 3G, A5/3 for GSM and EDGE, and GEA3 for GPRS. The SEC 3.0 is derived from integrated
security cores found in other members of the PowerQUICC II and PowerQUICC III families.
The security engine includes eight different execution units (EUs). Where data flows in and out of an EU,
each has buffer FIFOs of at least 256 bytes. EU types and features include the following:
