Abstract: Storing and retrieving ciphertext in data storage can include determining a first ciphertext value for a first data chunk to be saved to a client-server data storage system using an encrypted chunk hash value associated with the first data chunk as an initial value, and storing the first data chunk on a server in the client-server data storage system in response to determining that the first ciphertext value is a unique ciphertext value. Also, storing and retrieving ciphertext in data storage can include decrypting a ciphertext value for a second data chunk received from a client in the client-server data storage system and based on an encrypted chunk hash value associated with the second data chunk, and sending the second data chunk to the client in response to determining that the decrypted ciphertext value corresponds to an original data chunk saved to the server by the client.

Abstract translation: 在数据存储中存储和检索密文可以包括使用与第一数据块相关联的加密块哈希值作为初始值来确定要保存到客户端 - 服务器数据存储系统的第一数据块的第一密文值，并存储 响应于确定第一密文值是唯一的密文值，在客户机 - 服务器数据存储系统中的服务器上的第一数据块。 此外，在数据存储中存储和检索密文可以包括解密从客户机 - 服务器数据存储系统中的客户端接收的第二数据块的密文值，并且基于与第二数据块相关联的加密块哈希值， 响应于确定解密的密文值对应于由客户端保存到服务器的原始数据块，向客户端发送第二数据块。
