A bootable CD-ROM from a reliable source to verify signatures would be much
safer than no signatures at all. Even just running the signature
verification program from CD-ROM would make an attacker's problem more
difficult.
BTW - The problem is not trusted hardware. It is software that can isolate
untrusted programs and protect itself. Anything with an A or B NCSC
security rating would certainly be attractive. Trusted signature
verification hardware accessed by a compromised system can't be trusted.
(How do you know what was given to the hardware to be verified? How do you
know that the answer came from the hardware?)
