| Abstract | 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. |
