An important challenge for supporting multimedia applications in the Internet of
Things is the security heterogeneity of wired and wireless sensor and actuator networks.
In this work, we design a new and efficient media-aware security framework
for facilitating various multimedia applications in the Internet of Things. First,
we present a novel multimedia traffic classification and analysis method for handling
the heterogeneity of diverse applications. Then a media-aware traffic security
architecture is proposed based on the given traffic classification to enable various
multimedia services being available anywhere and anytime. Furthermore, we provide
a design rule and strategy to achieve a good trade-off between a system’s
flexibility and efficiency. To the best of our knowledge, this study is the first to provide
general media-aware security architecture by jointly considering the characteristics
of multimedia traffic, security service, and the Internet of Things.
