The pairing problem is to enable two devices, which share no prior context with each other, to agree upon a security association that they can use to protect their subsequent communication. Secure pairing should offer guarantees of the association partner's identity and it should be resistant to eavesdropping or to a man-in the middle attack. We propose a user friendly solution to this problem. Keys extracted from images of the participants are used for authentication. Details of the SAfE pairing system are presented along with a discussion of the security features and a usability analysis.
