Eurekalert April 26, 2024 A team of researchers in the US (UC San Diego, University of North Carolina, Purdue University, Georgia Tech, industry) introduced novel attack primitives that enable adversaries to leak (read) and manipulate (write) the path history register (PHR) and the prediction history tables (PHTs) of the conditional branch predictor in high-performance CPUs. These primitives enable two new classes of attacks: first, it can recover the entire control flow history of a victim program by exploiting read primitives as demonstrated by a practical secret-image recovery based on capturing the entire control flow of libjpeg routines. It can also […]

Better cybersecurity with new material
Science Daily September 4, 2023 Perovskite light emitting diodes (PeLEDs) has the potential to revolutionize the fields of optical communication and lighting devices, due to their simplicity of fabrication and outstanding optical properties. An international team of researchers (Sweden, Chile) has demonstrated that PeLEDs could be used in the field of quantum technologies by implementing a highly secure quantum random number generator (QRNG) which is posed to replace classical random number generators in applications such as encryption and gambling, and therefore need to be cheap, fast and have integration capabilities. Using a compact metal-halide PeLED source, the team generated random […]
