A system, method, and computer readable medium is disclosed for accessing an object that is encrypted within at least a tertiary-level encryption key scheme. This includes receiving a request to access blocks making up an object by content management system and using a top-level encryption key from a key management service, a namespace encryption key from a namespace encryption key database, and a respective block encryption keys protecting the blocks making up the object. Using these keys, the system can decrypt the block encryption keys using the namespace encryption key and decrypt the blocks using the block encryption keys, thereby providing access to the object.

Tertiary-level encryption key scheme

One variation of a system for implementing a key-value data store includes one or more processors, storage media and instructions stored in the storage media which, when executed by the system cause the system to: receive a request store a particular key-value item; request a first networked distributed data storage system to store the particular key-value item; based on a determination that a set of one or more offload criteria is satisfied: retrieve a first set of key-value items from the first networked distributed data storage system, and request a second networked distributed data storage system to store the first set of key-value items in a first set of one or more data objects. The first networked distributed data storage system can have a lower data write latency and a higher data storage cost than the second networked distributed data storage system.
