Carl is right. They want to GAK all keys including signature keys. Now think, to whom in your life are you willing to grant unlimited power of attorney? Your spouse? Your lawyer? Your banker? Your employer? Your government?

Giving away your signature key is worse. Not only can any key holder act FOR you, he can act AS you. "We've got you cold perp. You signed this child porn that was posted to alt.binary.etc. You can make your calls from jail." Who needs entrapment.

But, though things have gotten pretty bad these last 40 years, there are still courts, expert witnesses, and standards for signature verification. Experts are called upon to give testimony about the likelihood that a signature is that of the person claimed (by one side or the other). Though there have been few tests of digital signatures that I know of (I think Utah has a law...), this government access to identities (GAI) will throw a spanner in efforts to get digital signatures widely accepted. Once it gets shown in open court that Joe Blow can claim he did not sign a document and the government will have to admit that this is a possibility, and admits that anyone in government with access to the escrowed data base could have done the signing....well, digital signatures will lose much of their value immediately. Inasmuch as unforgeable digital signatures are critical for electronic commerce, a fact even Clinton cannot ignore, I expect this weakness to help sink Clipper III. As Carl noted, Cypherpunk Deep Cover Agent Micali has been doing a good job in planting logic bombs in these schemes...I urge we approve his bonus. --Tim May Boycott "Big Brother Inside" software!
