摘要：

Multi-core is widely used for mobile devices due to high performance and good energy efficiency. For maintaining cores' cache coherency, mobile multi-core integrated new hardware ARM CCI. In this study, we focus on the security aspect of mobile multi-core. We monitor cache coherency operations that occur among PSL related processes' inter core communication. After simple analysis, we can sneak android PSL information. Some preliminary results show that we could efficiently identify PSL pattern. This is a significant security violation in terms of confidentiality. In addition, mobile multi-cores are already prevalent, the attack is practical, and it can be easily spread.
