TL;DR: A deep-learning-based image encryption and decryption network (DeepEDN) is proposed to fulfill the process of encrypting and decrypting the medical image and can achieve a high level of security with a good performance in efficiency.

TL;DR: CaSE utilizes TrustZone and Cache-as-RAM technique to create a cache-based isolated execution environment, which can protect both code and data of security-sensitive applications against the compromised OS and the cold boot attack.

TL;DR: A new attack called SurfingAttack is designed that would enable multiple rounds of interactions between the voice-controlled device and the attacker over a longer distance and without the need to be in line-of-sight, and enables new attack scenarios, such as hijacking a mobile Short Message Service passcode, making ghost fraud calls without owners’ knowledge, etc.
