It may be that the methods Eugene cites are diversions to discourage looking too close at what is hidden in encryption packages. Public key escrow probably morphed into the usual secret government arrangements with comsec suppliers. Nothing encourages greater use of crypto than to believe it is secure, says those who laugh at how easy it is to foster faith in prayerful mathematics and cold dead hands. Meanwhile the secret keepers remain at maximum paranoia and make sure their bosses are too, to keep the endless bounty of research and counterintelligence funds coming. The hoohah the last few days about DoD ramping up even more its aggression against "cyber-security" attacks indicates that the spies cannot ever be too suspicious that somebody is out hoodwinking their hoodwink. Best to spy at home especially where the "best" inventors and implementors are dreaming of a lottery win. Enlisting crypto programmers and suppliers in the booty-fest is as simple as offering irresistable contracts, lipsticked with patriotism and rouged with being among the "smartest people in the world," not overlook lifetime economic security -- just as outlined in contract soliticitations and recruiting ads for NSA and CIA. The spies' retirement fund is as sweet as betrayal.
