DESCRIPTION

The MB91401 is a network security LSI incorporating a Fujitsu’s 32-bit, FR-family RISC microcontroller with 10/
100Base-T MAC Controller, encryption function and authentication function. The LSI contains an encryption
authentication hardware accelerator that boosts the LSI’s performance for encryption and authentication commu-
nication (IKE/IPsec/SSL) to be demanded fur ther.

The MAC controller has a packet filtering function that reduces the load on the CPU for an increasing amount of
packet processing. In addition, the board has the External interface for high-speed data communication with
various external hosts, USB ports as general-purpose interfaces, and various card interfaces.

FEATURES

••••

Encryption and authentication processing by hardware accelerator function

The LSI performs processing five times faster than by the conventional combination of encryption/authentication
hardware macros and software or about 400 times faster than by software only. In addition, CPU processing load
factor to be involved in the encryption and the authentication processing can be decreased to 1/5 or less.
Also, the LSI uses the embedded accelerator to execute that public-key encryption algorithm about 100 times
faster than by software processing, which generally puts an extremely heavy load microcontrollers.
