Abstract
In this work, we propose a novel secure key agreement
protocol, Secure Key Agreement using Pure Ordered
Biometrics (SKA-POB), in which the cryptographic keys are
generated using an ordered set of biometrics, without any
other helper data. The proposed approach is realized using iris
biometrics. Our protocol makes use of hash functions, and we
propose a window-based comparison strategy and a window reset
method. This way, performance is maximized without sacrificing
security. SKA-POB protocol works in round manner, allowing to
successfully terminate with key establishment as early as possible
so that the complexity is reduced for both client and server sides.
Additionally, we employ multi-criteria analyses for our proposed
SKA-POB protocol and we provide verification results in terms of
performance analysis together with randomness, distinctiveness
and attack complexity through security analysis. Results show
that highly random and secure keys can be generated with almost
no error and with very low complexity
