A quick try on google revealed a couple of hits indicating that yes DSP chips are used for IPSec encryption/decryption.

Seeing that, and knowing that a DSP ( digital signal processor ) is a computationally speedy IC used for processing complex signals associated with real time audio and video, it occurs to me that why couldn't the architecture be used to service the computationally intense processing that IPSEC entails?
