Our department’s professor Seungwon Shin’s research team has announced findings that the data prefetching feature in Apple’s new M-series processors can be more effectively exploited for traditional cache attacks. Data prefetching is one of the key optimization functions of a processor, used to reduce memory access time by preloading data into the cache that the program is expected to need.\u00a0<\/span><\/div>\n
\u00a0<\/div>\n
Processors typically provide hardware-based prefetching along with a set of instructions to support software-based prefetching. Professor Seungwon Shin’s team conducted a comparative analysis of the Instruction Set Architectures (ISA) of x86 and ARM, proving that the data prefetching feature on ARM-based processors can be more effectively utilized for cache attacks. <\/span><\/div>\n
Through this research, they devised three new cache-based attacks and demonstrated that a covert channel implemented on Apple’s M-series processors could transmit data at over three times the speed of traditional cache attacks. Additionally, they proved approximately 8 times performance improvement in side-channel attacks that extract encryption keys compared to previous works.\u00a0<\/span><\/div>\n
\u00a0<\/div>\n
Professor Seungwon Shin’s team emphasized the significance of starting the research on security vulnerabilities in ARM-based processors, especially as Apple has started to manufacture desktop processors based on ARM architecture.<\/span><\/div>\n
This study will be presented at USENIX Security, one of the top conferences in computer security, in August 2024 and can be found on the conference’s website.\u00a0<\/span><\/div>\n
