Abstract: The subject disclosure is directed towards encryption and deduplication integration between computing devices and a network resource. Files are partitioned into data blocks and deduplicated via removal of duplicate data blocks. Using multiple cryptographic keys, each data block is encrypted and stored at the network resource but can only be decrypted by an authorized user, such as domain entity having an appropriate deduplication domain-based cryptographic key. Another cryptographic key referred to as a content-derived cryptographic key ensures that duplicate data blocks encrypt to substantially equivalent encrypted data.

Abstract translation: 主题公开涉及计算设备和网络资源之间的加密和重复数据删除集成。 文件被分割成数据块，并通过删除重复的数据块进行重复数据删除。 使用多个加密密钥，每个数据块被加密并存储在网络资源中，但是只能由授权用户（例如具有适当的基于重复数据删除域的加密密钥的域实体）解密。 被称为内容导出加密密钥的另一密码密钥确保重复的数据块加密到基本相等的加密数据。
