And getting back to my original question, is it pointless to search

for a secure DSP that fits my needs?

It's not pointless. But I'd go for a low-volume, full-custom ASIC

with the algorithms in an implant ROM (to thrwart microscopic

examination) and enough heavy-duty potting material applied to the

chip that it would be difficult to deprocess it and E-beam it.

If you instead use a standard DSP chip, even with security measures the

adversary already has an idea of how to penetrate it
