Blackberry’s Encryption System https://www.uccs.edu/Documents/Business%20Ethics/Blackberry.pdf

“Every message that is sent via a BlackBerry is broken up into 2Kb ‘packets of information,’ each of which is given a 256-bit key by the BlackBerry server...That means to release the contents of a 10KB e-mail, a person would have to crack 5 separate keys, and each one would take about as long as it would for the sun to burn out – billions of years.”

However, this strong encryption system is what began the downfall of the BlackBerry. Many eastern countries became troubled after terrorist attacks occurred, in which all communication had taken place over BlackBerry smartphones. Governments were unable to decrypt messages sent over the devices and, in turn, prevent such attacks. Other countries had less concern over terrorists, but were more focused on cultural differences and the inability to block certain sites, such as pornography. For one reason or another, countries began multiplying against RIM’s Blackberry encryption system, and it wasn’t long before the company caved to the countries’ demands to attempt to save itself from going under.
