The sources provide a comprehensive analysis of methods for securing image data, focusing on integrating Public Key Cryptography (PKC) directly into image sensors and signal processing pipelines. The technical report advocates for the use of Elliptic Curve Cryptography (ECC) over RSA for on-sensor security due to ECC's advantages in speed, power efficiency, and smaller silicon area, arguing that security must be established at the point of creation, safeguarded by a Hardware Root of Trust (RoT). Concurrently, the academic paper discusses mitigating backdoors and security threats, such as subliminal channels in IP cameras, by proposing a backdoor-free Random Number Generator (RNG) that harvests entropy from the image sensor's dark shot noise without requiring additional hardware. A third source investigates hybrid encryption schemes, such as ECC combined with symmetric algorithms like Hill Cipher or AES, for general image encryption, evaluating their performance based on metrics like encryption time and entropy to determine the most suitable approach for varying application needs.
