Biometric based authenticated key exchange

摘要

A method includes receiving a first biometric data set representative of a first biometric sample provided by a user and public parameters. The method includes generating a first set of exchange information based thereon and communicating it to a system server. The method includes receiving a second set of exchange information based on the public parameters and a second biometric data set representative of a second biometric sample and is symmetric with respect to the first set of exchange information. The method includes computing a session key for the communication session by applying a first hash function based on a hash key to a subset of the second set of exchange information and a second hash function based on a projected key to a subset of the first set of exchange information. The method includes using the session key in communications during the communication session.
