According to the India Times, the Indian Department of Telecommunications has succeeded in decrypting messages sent to Blackberry devices:

“Decompression is being tested in operator’s network with three successful testing on Bharti Airtel, Reliance Communication and BPL Mobile,” a source in DoT said. He, however, added that the solution reached upon would not be shared with anybody including the national telecom service providers like BSNL or MTNL.

There has been talk about this before, and RIM has always maintained that they don’t have the encryption keys used by their clients.

There has been no independent confirmation of an attack against the Blackberry encryption yet, and I find it hard to believe; data between the Blackberry and the Enterprise Server it connects to is encrypted with either 3DES or AES encryption.

The BlackBerry Enterprise Solution offers two transport encryption options, Advanced Encryption Standard (AES) and Triple Data Encryption Standard (Triple DES)*, for all data transmitted between BlackBerry® Enterprise Server and BlackBerry smartphones.

Private encryption keys are generated in a secure, two-way authenticated environment and are assigned to each BlackBerry smartphone user. Each secret key is stored only in the user’s secure enterprise account (i.e., Microsoft® Exchange, IBM® Lotus® Domino® or Novell® GroupWise®) and on their BlackBerry smartphone and can be regenerated wirelessly by the user.
