We use grip pattern based biometrics as a secure side channel to achieve pre-authentication in a protocol that sets up a secure channel between two hand held devices. The protocol efficiently calculates a shared secret key from biometric data. The protocol is used in an application where grip pattern based biometrics is used to control access to police hand guns. Key Words: Ad-hoc authentication, fuzzy cryptography, biometrics;
