Canadian MP Pushes for Legislation to Lower BlackBerry Security

The BlackBerry makes it hard for law enforcement to investigate crimes

The security of the BlackBerry smartphones and their communications, one of the features that has made them so popular, is making certain police investigations impossible, a Liberal member of the Canadian Parliament argues. Therefore, she has reintroduced a bill that forces wireless service providers to make the technology easier to tap.

The BlackBerry represents one of Canada's best examples of successful businesses. The widespread smartphone is designed and manufactured by Research In Motion (RIM), a company headquartered in Waterloo, Ontario. In October 2008, RIM was included on the list of "Canada's Top 100 Employers."

Initially designed for the corporate environment, the BlackBerry was quickly adopted by businessmen, politicians, security professionals, law enforcement officials and generally anyone concerned with the privacy of their messages. Even the President of the United States is using such a device, most likely with some modifications made to it.

RIM develops all of the handset's underlying software in-house, including the BlackBerry Enterprise Server (BES), used by providers and enterprises to interconnect the smartphones. BES employs strong encryption for all communications, making it nearly impossible for them to be intercepted.

According to Supt. Pat Fogerty of the Combined Forces Special Enforcement Unit of British Columbia, the criminals also prefer using these devices to avoid being caught. "They completely know that this technology is to their advantage, and they will stay on that technology until such time that there is new technology that will be even more secure," he comments for CBC News.

In addition to the "built-in" security, the outlaws apparently also employ extra software to add multiple layers of encryption to their transmissions. This is not to the liking of Liberal MP Marlene Jennings, who says that wiretapping is "an essential tool for the battle against crime."

Ms. Jennings is currently pushing for a bill dating back to 2005 that would force telecommunications providers to adapt their technologies and make it easier to intercept communications. Entitled "the Modernization of Investigative Techniques Act (MITA)," the bill was introduced and rejected two times before, in 2006 and 2007.

The companies have expressed concerns over the costs of meeting the requirements formulated in this proposed act, but the Liberal MP explains that the government could cover part of them. According to CBC News, Canada already has problems with the wiretapping legislation, which, for example, does not currently require obtaining a warrant in order to force providers into disclosing information about their customers.

Hmmm... I don't follow the logic of the RCMP and Ms Jennings. To conduct a wiretap, the law enforcement authorities in question need a warrant from a judge. If they have a warrant, can they not ask RIM and/or the service provider for help in accessing the phone calls in question? If they don't have a warrant, then the technical difficulties with evesdropping on the system are irrelevant. Or am I missing something here?

Hello Paul,

Thank you for commenting.

The wireless provider only serves as carrier for the data. It does not perform the encryption on its end. This means that if a provider is served with a warrant, the best it can do is provide the authorities with the encrypted data that is passed along from a device to another. It does not have the means to decrypt it, because it has no role in encrypting it in the first place.

Furthermore, the encryption used by the BlackBerry is 256-bit AES, a very strong algorithm that has not been cracked yet, so there is no chance for the authorities to decrypt the data, without the proper keys.

The interesting thing is that this is not actually limited to the BlackBerry. For example, such strong encryption can also be used for e-mail messages sent from desktop computer e-mail clients. I encrypt the e-mail on my end with a key, then send it to you. On your end you have another key, which can be used to decrypt it. This means our Internet service providers will only "see" the encrypted data when they pass it along.

In order to decrypt it, the authorities would have to get the key from you. To do this, they would require a search warrant for your computer. This can very well happen, but then it exceeds the purpose of wiretapping, which aims at intercepting the conversations without your knowledge in order to build a case against you.

Hope this clears things up a bit.
