METHOD AND SYSTEM FOR SECURING INSTRUCTION CACHES USING SUBSTANTIALLY RANDOM INSTRUCTION MAPPING SCHEME |
摘要 |
A method and system is provided for securing micro-architectural instruction caches (I-caches). Securing an I-cache involves maintaining a different substantially random instruction mapping policy into an I-cache for each of multiple processes, and for each process, performing a substantially random mapping scheme for mapping a process instruction into the I-cache based on the substantially random instruction mapping policy for said process. Securing the I-cache may further involve dynamically partitioning the I-cache into multiple logical partitions, and sharing access to the I-cache by an I-cache mapping policy that provides access to each I-cache partition by only one logical processor.
