| Abstract: | In a forensic setting breaking the encryption of Android phones of suspects is very relevant to obtain evidence. Cache eviction attacks are a method that can be used for this. Those attacks can be used to profile an application, i.e. obtain information on timings within the execution. These timings could be used as the basis for further attacks, such as fault-injection attacks or to obtain information about the execution flow of the victim program. We show Flush+Reload profiling on OpenSSL AES, and Prime+Probe profiling on the RSA implementation used to verify ARM TrustZone applications (trustlets). These attacks are executed in a bare-metal environment, which leads to reliable results due to the lack of operating system interference. In addition to the attacks we provide an overview of the state of the art of ARM cache side-channel attacks. |
