A Trapdoor Hash Based Mechanism for Stream Authentication
Abstract—
Digital streaming Internet applications such as online gaming, multimedia
playback, presentations, news feeds, and stock quotes involve end-users with very
low tolerance for high latency, low data rates, and playback interruption. To
protect such delay-sensitive streams against malicious attacks, security
mechanisms need to be designed to efficiently process long sequence of bits. We
study the problem of efficient authentication for real-time and delay-sensitive
streams commonly seen in content distribution, multicast, and peer-to-peer
networks. We propose a novel signature amortization technique based on trapdoor
hash functions for authenticating individual data blocks in a stream. Our technique
provides: 1) Resilience against transmission losses of intermediate blocks in the
stream; 2) Small and constant memory/compute requirements at the sender and
receiver; 3) Minimal constant communication overhead needed for transmission of
authenticating information. Our proposed technique renders authentication of
digital streams practical and efficient. We substantiate this claim by constructing
DL-SA, a discrete-log-based instantiation of the proposed technique. DL-SA
provides adaptive stream verification, where the receiver has control over
modulating computation cost versus buffer size. Our performance analysis
demonstrates that DL-SA incurs the least per-block communication and signature
generation overheads compared to existing schemes with comparable features.
