The Protected Keyboard AN140

The Protected Keyboard AN 140 is fully analogous to ordinary keyboard. It is used in cases when the distances from computer to the border of object (where supposed offender can be) are small and the generators of masking electro-magnetic noise could not be implemented. This device doesn't create any additional information leakage channels. Also Protected Keyboard AN 140 ensures the guaranteed protection of data inputted by operator. The form of AN 140 is performed in Figure 3, the construction of device is based on patented method of information protection.

The main feature of AN 140 is that its original interface for transferring the keystrokes Scan Codes is used. Due to such a solution information inputted from Protected Keyboard can't be intercepted from electro-magnetic emission leakage channels.
