SIMF: Single-Instruction Multiple-Flush Mechanism for Processor Temporal Isolation

Abstract Microarchitectural timing attacks exploit shared on-core state components like caches and TLBs, which are traditionally mitigated inefficiently using software-based flushing instructions. This paper introduces SIMF (Single-Instruction Multiple-Flush), a specialized hardware mechanism implemented
