我们提出了一种针对特定应用程序定制的对称加密原语：外包存储。该设置假设内存受限的计算设备通过让其他（不受信任的）设备保存它们应请求返回的信息的副本来增加其可用的易失性或永久性内存的量。例如，Web服务器通常为每个客户端连接保存大量数据，从用户偏好到数据库凭据等技术信息。如果每个会话的数据量相当大，那么忙碌的服务器迟早会耗尽内存。对此的一个可接受的解决方案是让服务器将会话数据加密到其自身，并让客户端存储密文，同意客户端在每个后续请求中再现密文（例如，通过cookie），以便在需要时可以恢复会话数据。
We put forward a symmetric encryption primitive tailored towards a specific application: outsourced storage. The setting assumes a memory-bounded computing device that inflates the amount of volatile or permanent memory available to it by letting other (untrusted) devices hold encryptions of information that they return on request. For instance, web servers typically hold for each of the client connections they manage a multitude of data, ranging from user preferences to technical information like database credentials. If the amount of data per session is considerable, busy servers sooner or later run out of memory. One admissible solution to this is to let the server encrypt the session data to itself and to let the client store the ciphertext, with the agreement that the client reproduce the ciphertext in each subsequent request (e.g., via a cookie) so that the session data can be recovered when required.
