A method, system and devices for enabling secure pairing between two communication devices equipped with a minimal user interface includes determining a verification pattern based upon security information exchanged between the two communication devices and presenting the verification pattern in a manner that can be perceived by a user who can determine whether the verification patterns are the same. The verification patterns may be presented as flashing light displays, such as flashing sequences of a light emitting diode, or as sounds, such as tones or click patterns emitted by a speaker. If a user perceives that the verification patterns emitted by both communication devices are the same, the user may so indicate by pressing a button on each of the devices. Obtaining such user confirmation of the verification patterns enables establishing a secure pairing between the two communication devices that is protected from active and passive eavesdropping.
