TECHNIQUES TO MITIGATE CACHE-BASED SIDE-CHANNEL ATTACKS - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18214870 Titled 'TECHNIQUES TO MITIGATE CACHE-BASED SIDE-CHANNEL ATTACKS'
Simplified Explanation
The abstract discusses various techniques to protect against cache-based side-channel attacks. These attacks involve accessing sensitive data stored in a cache. One approach mentioned is assigning a class of service (COS) to different cores of a process. This helps determine if a potentially malicious application is trying to access a cache line in a processor cache, and alerts the operating system accordingly. Another technique involves marking certain pages in an application's memory address space as unflushable. This prevents a potentially malicious application from accessing sensitive data that is loaded into the processor cache. Overall, these methods aim to mitigate or prevent cache-based side-channel attacks.
Original Abstract Submitted
Examples include techniques to mitigate or prevent cache-based side-channel attacks to a cache. Examples include use of assigned class of service (COS) assigned to cores of a process to determine whether to notify an OS of a potential malicious application attempting to access a cache line cached to a processor cache. Examples also include marking pages in an application memory address space of a processor cache as unflushable to prevent a potentially malicious application from accessing sensitive data loaded to the application memory address space of the processor cache.
