64-bit encryption broken after four years

James Middleton, vnunet.com 30 Sep 2002

After millions of hours of processor work and four years of human effort, the RC5 64-bit encryption algorithm has finally been broken.

After 15,769,938,165,961,326,592 keys, a PC in Tokyo returned the winning solution to the Distributed.net key servers.
Expert Attempts to Crack RSA Encryption

Since the RSA algorithm was publicly announced in 1977, breaking open the codes it generates has gone from being a bad faculty cocktail party parlor trick to a multi national coordinated effort by increasing the length of the asymmetrical keys used in the encryption process. The larger the prime numbers used to generate a key the more time is required to unravel it.

As elegant as that math is, today’s RSA encryption keys require brute force computing to crack. Ten of thousands of processors have been working in concert across the internet to break open a 72 bit key since December of 2002 with no success.

The 1024 bit encryption key used by Cipherphone Cipherphones that will be broken by a similar coordinated effort some time in 22nd century but we make that timeline irrelevant by seamlessly altering the key every second during a secured transmission. Simply put the computer power needed to hack into this system doesn’t exist.

The Nokia N70 with the G-L Cipherphone encryption software is the perfect choice for governmental agencies, politicians, police, lawyers, executives and anyone else who recognizes the need to prevent confidential information from falling into the wrong hands.
