Highly Trustworthy In-Sensor Cryptography for Image Encryption and Authentication

Abstract: The prevailing transmission of image information over the Internet of Things demands trustworthy cryptography for high security and privacy. State-of-the-art security modules are usually physically separated from the sensory terminals that capture images, which unavoidably exposes image information to various attacks during the transmission process. Here we develop in-sensor cryptography that enables capturing images and producing security keys in the same hardware devices. The generated key inherently binds t… Show more

“…In addition, the integration of biosensors and memristive devices for cognitive computing of biosignals can provide possibilities for on-skin computing and diagnosis. In addition, the random nature of memristive devices can be exploited in some applications, such as encryption techniques 409 and stochastic computing, where device variability is not a flaw but rather an attribute that can be leveraged (Figure 30b). Overall, further improvements in memristive devices, algorithms, architectures, and systems will enable memristive technology to reach its full potential in nextgeneration computing.…”

“…Chai et al developed an in-sensor cryptography based on phototransistor arrays in which the entropy source from the physical structure of the hardware provided the foundation for generating irreproducible keys. [10] This in-hardware cryptography could encrypt the captured image and demonstrate great application potential in image information transmission.…”

“…As a class of devices that convert light signals into electrical signals, PDs can process the information transmitted by light, with a broad scope of applications in image sensing, encrypted optical communications, wearable health monitoring, military defense, etc. [6][7][8][9][10][11] Similar to the sensory neurons in the retina of the human visual systems, OSDs can process and store visual information while sensing optical stimuli, enabling the integration of perception, computational, and memory functions required for pattern recognition and object detection in a single device. [12][13][14] Fundamental and critical biological synaptic behaviors can be emulated on OSDs through modulation of synaptic weights by optical stimuli.…”
