Security Engine (SEC) 2.1
This chapter describes the functionality of the integrated security engine (SEC 2.1) of the MPC8544E. It
addresses the following topics:
The SEC 2.1 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 MPC8544E. It is
optimized to process all the algorithms associated with IPSec, IKE, SSL/TLS, iSCSI, SRTP, and 802.11i.
The SEC 2.1 is derived from integrated security cores found in other members of the PowerQUICC family,
including the SEC 2.0, the version implemented in the MPC8555E and MPC8541E.
The security engine’s execution units (EUs) and primary features include the following:
