ARCHITECTURAL PRINCIPLES FOR SECURE STREAMING & SECURE ADAPTATION
IN THE DEVELOPING SCALABLE VIDEO CODING (SVC) STANDARD

ABSTRACT
Scalable video coding has long been known to provide important
functionalities such as low-complexity adaptation for diverse clients
with different resources and for delivery over heterogeneous net-
works with time-varying available bandwidths. Recent advance-
ments in scalable video coding have significantly improved the achiev-
able compression performance, and the Scalable Video Coding (SVC)
standard is currently under intense development. An additional capa-
bility of scalable coding, which we believe has received less attention
than it deserves, is the possibility with careful cross-layer design to
support secure adaptive streaming at an untrustworthy sender and se-
cure adaptation at an untrustworthy mid-network node. Building on
the Secure Scalable Streaming framework for video, and its realiza-
tion within the JPEG-2000 Security (JPSEC) standard, we describe
the architectural principles and design details necessary so that SVC
