Aria: Tolerating Skewed Workloads in Secure In-memory Key-value Stores

The recent advent of the hardware trusted execution environment (TEE), e.g., Intel SGX, enables encrypted and integrity-verified in-memory key-value (KV) stores. However, due to the architectural limitations of the hardware, it is non-trivial to build a secure in-memory KV store with SGX without compromising the performance. The reason comes from (i) the limited memory capacity the SGX TEE provide...
