• We proposed an efficient authentication scheme for H.264/Scalable Video Coding.
• We implemented and evaluated schemeʼs performance in lossy wireless mobile network.
• The proposed scheme achieves higher verification rate compared to existing scheme.
• The proposed scheme has lower communication overhead and decoding delay.
• The proposed scheme preserves the scalabilities of H.264/Scalable Video Coding.

In this paper, a bit stream-based authentication scheme for H.264/Scalable Video Coding (SVC) is proposed. The proposed scheme seamlessly integrates cryptographic algorithms and Erasure Correction Codes (ECCs) to SVC video streams such that the authenticated streams are format compliant with the SVC specifications and preserve the three-dimensional scalability (i.e., spatial, quality and temporal) of the original streams. We implement our scheme on a smart phone and study its performance over a realistic bursty packet-lossy wireless mobile network. Our analysis and experimental results show that the scheme achieves very high verification rates with lower communication overhead and much smaller decoding delay compared with the existing solutions.
