• Abstract: Delivering high-quality, secure 360{\deg} video content introduces unique challenges, primarily due to the high bitrates and interactive demands of immersive media. Traditional HTTPS-based methods, although widely used, face limitations in computational efficiency and scalability when securing these high-resolution streams. To address these issues, this paper proposes a novel framework integrating Attribute-Based Encryption (ABE) with selective encryption techniques tailored specifically for tiled 360{\deg} video streaming. Our approach employs selective encryption of frames at varying levels to reduce computational overhead while ensuring robust protection against unauthorized access. Moreover, we explore viewport-adaptive encryption, dynamically encrypting more frames within tiles occupying larger portions of the viewer's field of view. This targeted method significantly enhances security in critical viewing areas without unnecessary overhead in peripheral regions. We deploy and evaluate our proposed approach using the CloudLab testbed, comparing its performance against traditional HTTPS streaming. Experimental results demonstrate that our ABE-based model achieves reduced computational load on intermediate caches, improves cache hit rates, and maintains comparable visual quality to HTTPS, as assessed by Video Multimethod Assessment Fusion (VMAF).

  Homomorphic Encryption (FHE) enables computations on encrypted data, preserving confidentiality without the need for decryption. Traditional FHE methods often encrypt images by monolithic data blocks, instead of pixels. We propose and implement a pixel-level homomorphic encryption approach, iCHEETAH, based on the CKKS scheme.

  BlockCopy is a scheme that accelerates pretrained frame-based CNNs to process video more efficiently.

Features of non-selected regions are simply copied from the preceding frame, reducing the number of computations and latency.
