Processing Overview
Page 5
The BCM5802 performs authentication using the DSA algorithm for an IPsec session during IKE handshake in the following
stages:
1
Fetch command context and message through DMA.
2
If the required operation is to sign message, generate a random number and compute r and s values using SHA-1 and
key setup execution units.
3
If the required operation is to verify signature, compute v value using SHA-1 and key setup execution units.
4
Write the output to the output buffer.
