The All-out Attack strategy reveals that miners can exploit Pay-Per-Share schemes to maximize gains while leaving honest miners and pool operators at a disadvantage.
Relay nodes can reconstruct semantic information with surprising accuracy, exposing a critical privacy flaw in current SemCom systems.
A stealthy low-power backdoor attack can selectively manipulate semantic inference in shared-access wireless networks, exposing significant vulnerabilities in current SemCom systems.
A simple tweak to a known blockchain attack鈥攍imiting the withholding time鈥攜ields 22x greater rewards for attackers in realistic scenarios, exposing a major weakness in pooled mining incentives.
Sharing randomness across all servers in a graph-based database system boosts private information retrieval capacity, outperforming schemes where randomness is tied to individual message replicas.
