With the ever-increasing virtualization of software and hardware, the privacy of user-sensitive data is a fundamental concern in computation outsourcing. Secure processors enable a trusted execution environment to guarantee security properties based on the principles of isolation, sealing, and integrity. However, the shared hardware resources within the microarchitecture are increasingly being used by co-located adversarial software to create timing-based side-channel attacks. State-of-the-art secure processors implement thestrong isolationprimitive to enable non-interference for shared hardware but suffer from frequent state purging and resource utilization overheads, leading to degraded performance. This article proposes ASM, an adaptive secure multicore architecture that enables a reconfigurable, yet strongly isolated execution environment. For outsourced security-critical processes, the proposed security kernel and hardware extensions allow either a given process to execute using all available cores or co-execute multiple processes on strongly isolated clusters of cores. This spatio-temporal execution environment is configured based on resource demands of processes, such that the secure processor mitigates state purging overheads and maximizes hardware resource utilization.
