Abstract: A storage service receives a binary large object (blob) for storage, and the service creates first and second sets of data chunks from the blob. The chunks in the first set together equal the blob, and the service uses one or more encryption keys to encrypt each of the data chunks in the first set. The chunks in the second set also together equal the blob. The service assigns a message authentication code (MAC) to each data chunk in the second set. The service stores the encrypted data chunks in one or more data stores, and it stores the encryption keys and the MACs as metadata in a metadata memory.
Abstract translation: 存储服务接收用于存储的二进制大对象(blob),并且该服务从该Blob创建第一组和第二组数据块。 第一组中的块一起等于blob,并且该服务使用一个或多个加密密钥来加密第一组中的每个数据块。 第二集中的块也在一起等于斑点。 服务将消息认证码(MAC)分配给第二组中的每个数据块。 该服务将加密的数据块存储在一个或多个数据存储中,并且将加密密钥和MAC作为元数据存储在元数据存储器中。
