Every single implementation of cryptography would be required to encrypt the message both with the original key and separately with the government master key, and store / transmit both. The master key suddenly becomes very valuable, and the incentive to crack it is enormous. In addition, there would be an enormous amount of ciphertext available that's encrypted with that key, and it would likely be shared widely across government.
Also, wouldn't this require severely limiting the number of permitted encryption algorithms?
- dTal 9y agoA clever system would easily mitigate your first point, probably with some sort of rolling key + key hierarchy (much like SSL and certificate authorities). As to your second point, yes. It would require severely limiting a great deal of things. Consider that "impossible" at your peril.
