Abstract :

Data confidentiality over mobile devices can be difficult to secure due to a
lack of computing power and weak supporting encryption components.  However,
modern devices often have multiple wireless interfaces with diverse channel
capacities and security capabilities.  We show that the availability of
diverse, heterogenous links (physical or logical) between nodes in a network
can be used to increase data confidentiality, on top of the availability or
strength of underlying encryption techniques.  We introduce a new security
approach using multiple channels to transmit data securely, based on the idea
of deliberate corruption, and information reduction, and analyze its security
using the information theoretic concept of secrecy capacity, and the wiretap
channel.  Our work introduces the idea of channel design with security in mind.
