EnclaveCache: A Secure and Scalable Key-value Cache in Multi-tenant Clouds using Intel SGX

Abstract

With in-memory key-value caches such as Redis and Memcached being a key component for many systems to improve throughput and reduce latency, cloud caches have been widely adopted for small companies to deploy their own cache systems. However, data security is still a major concern, which affects the adoption of cloud caches. Tenant’s data stored in a multi-tenant cloud environment faces threats from both co-located other tenants, as well as the untrusted cloud provider.
