Polar Codes based on Bit Flipping Improved BP Decoding Algorithm
Guangtongxin yanjiu, 2021 Polar codes is the only coding scheme in the world that has been proved that the Shannon threshold is reachable. Because of the high time delay caused by the serial characteristic of Successive Cancellation (SC) decoding, the Belief Propagation (BP ...

Eliminating eBPF Tracing Overhead on Untraced Processes
Current eBPF-based kernel extensions affect entire systems, and are coarse-grained. For some use cases, like tracing, operators are more interested in tracing a subset of processes (e.g., belonging to a container) rather than all processes.

fProcessor: NonIntrusive and On-the-Fly File Data Preprocessing Using eBPF
IEEE AccessThis paper introduces fProcessor, a tool designed for nonintrusive, on-the-fly preprocessing of data being written to files. “Nonintrusive” means that fProcessor requires no modifications to existing code, allowing applications to remain ...

An Abnormal File Access Detection Model for Containers Based on eBPF Listening
MathematicsWith the widespread adoption of container technology, its shared kernel architecture has made abnormal file access behavior a key precursor to container escape and lateral attacks, necessitating precise and efficient runtime detection mechanisms. However,
