摘要： Various systems and methods for detecting and preventing side-channel attacks, including attacks aimed at discovering the location of KASLR-randomized privileged code sections in virtual memory address space, are described. In an example, a computing system includes electronic operations for detecting unauthorized attempts to access kernel virtual memory pages via trap entry detection, with operations including: generating a trap page with a physical memory address; assigning a phantom page at an open location in the privileged portion of the virtual memory address space; generating a plurality of phantom page table entries corresponding to an otherwise-unmapped privileged virtual memory region; placing the trap page in physical memory and placing the phantom page table entry in a page table map; and detecting an access to the trap page via the phantom page table entry, to trigger a response to a potential attack.

摘要： The disclosure generally provides methods, systems and apparatus to construct a Physically Unclonable Function (PUF) value for an electronic package based on the package's internal components and their interconnects. In one embodiment, the package is a System-On-Chip (SOC) having a plurality of dielets and a plurality of interconnect connecting the dielets. Each of the dielets and each of the interconnects (at one or more locations) may define an entropy source. each entropy source may have an entropy value. Each entropy source communicates an initial entropy value to a PUF aggregator. The PUF aggregator receives and/or aggregates the various entropies from the various entropy sources to construct the native SOC PUF value. The native SOC PUF value defines the authentic PUF value of the SOC at SOC release. Any deviation from the native SOC PUF value may be deemed a security breach of the SOC.

摘要： In one embodiment, memory cell includes a control gate, a floating gate, a substrate comprising a source region and a drain region, a first isolator between the control gate and floating gate, and a second isolator between the floating gate and the substrate. The memory cell is configured to have a retention time that is within a statistical window around a selected lifespan. The selected lifespan may be less than ten years, such as, for example, less than one year, less than one month, or less than one week.
