Foil 21 Export Restrictions on Cryptography

From Basic Principles of Java and Internet Security CPS616 Web Technologies -- Spring 98. by Geoffrey C. Fox


1 The US government has established restrictions on the "quality" of encryption software that can be exported
2 This actually translates into general restrictions on security quality as vendors do not want two types of software -- one domestic and one foreign!
3 Note one can break "low quality" encryption e.g. RSA155 (best technology using 512 binary bits) would take 10,000 PC's a few months to break
  • However the bad guys might to do this to break into Fort Knox but wouldn't bother for your credit card number!
4 Sun ingeniously released latest software using cryptography produced entirely outside the USA and so again the government is attempting something that is bound to fail!
