SHIELD: Encrypting Persistent Data of LSM-KVS from Monolithic to Disaggregated Storage

Summary: Proposes two encryption designs for LSM-KVS persistent data in monolithic and DS: an instance-level approach and SHIELD, with fine-grained write-path encryption and per-file keys. WAL buffering and a metadata-enabled DS key-sharing cache reduce overhead; RocksDB shows 0–32% (instance) and 0–36% (SHIELD). (summarized by gpt-5-nano on Feb 09 2026)
