Never is a strong word and an accurate one in this scenario.Never is a strong word.....................
others will vigorously disagree,,but technology is going there..
But then a 16 yr old kid from Ireland cracked RSA back in 2007 when it was said to be "secure" enough for government use.I read somewhere it would take a supercomputer 30+ years to generate keys and try each combination possible... and since administrators can easily change keys, the process would need to start over and over. Sounds pretty impossible to me.
All very true. I doubt there will ever be a way to fully protect an RF radio signal with 100% certainty.But then a 16 yr old kid from Ireland cracked RSA back in 2007 when it was said to be "secure" enough for government use.
WiFi WEP-40 and WEP2 (104) were thought to be secure, yet both were "cracked" within 2 years of being adopted as THE WiFi SECURITY STANDARD for the 21st Century.
The German Enigma machines of WWII were supposedly the pinnacle of encryption technology of their time. Yet the Polish had actually decrypted them even before the outbreak of war in 1939. The Germans added more complexity to it making it harder to crack, so the British threw more computing power (read that as "Ultra", a.k.a. human brains) at it and continued to decrypt it. When timeliness became an issue, the Allies simply stole a machine. Several in fact.
Moore's Law will always win in the end. It all comes down to how much computing power can be thrown at something and how timely it is needed. And as the Allies figured out, if you can't decrypt it quickly, steal a machine and decrypt just like the other guys. We already see a blackmarket in stolen police radios with encryption tech installed. Drug dealers don't leave home without it. The bottom line is, if you can read it legally, someone else is going to figure out how to read it illegally....
