The organization has invited potential applicants to solve a visual code posted at website.

The challenge has also been "seeded" to social media sites, blogs and forums.

A spokesman said the campaign aimed to raise the profile of GCHQ to an audience that would otherwise be difficult to reach.

"The target audience for this particular campaign is one that may not typically be attracted to traditional advertising methods and may be unaware that GCHQ is recruiting for these kinds of roles," the spokesman said.

"Their skills may be ideally suited to our work and yet they may not understand how they could apply them to a working environment, particularly one where they have the opportunity to contribute so much."

The competition began in secret on November 3rd and will continue until December 12th.

imageTwo researchers from the University of California at Davis Hao Chen and Lian Cai found a way to determine, which keys have been pressed on the screen’s keypad of OC Android by measuring the shift of vibration and wobbliness of the device that were measured by the built-in accelerometer. This is important, because the data from the accelerometers were not considered as a potential vector of attack, and thus freely available to any application on any Smartphone or pad.

Eavesdropping of keylogging on a desktop or laptop computer with Windows or Mac is incredibly simple: install the appropriate program (or Trojan virus it will do for you), set up where it should be saved or sent the stolen key’s codes, and that is all! When it comes to Smartphones, however, the complex systems of access restrictions make this approach almost impossible unless the side-channels will be used. Strictly speaking, a side-channel is open source of information, which helps the attacker to crack the cryptographic system. In a broader sense, a side-channel may be a light indicator on the router that blinks during the data being transferred, or the keylogging’ sounds of a keypad. [Note: here were mention the real variety of attacks] In other words, the side-channels are characteristics of the system, which potential danger is overlooked.
