    Abstract: System, computer readable medium and method for decryption. The method may include receiving, by a third computerized system and from a fourth computerized system, a first encrypted file entity key and signed access metadata. The first encrypted file entity key is created by encrypting a file entity key by a first computerized system using an encryption key of a second computerized system. The signed access metadata is signed by the file entity key. The encrypted file entity is created by encrypting a file entity by the first computerized system using the file entity key. Sending, by the third computerized system, the signed access metadata and the first encrypted file entity key to the second computerized system. Receiving a response from the second computerized system. Determining, based on the response from the second computerized system, whether to facilitate a decryption of the encrypted file entity by the fourth computerized entity.

    Abstract: An approach is proposed that contemplates systems, methods, and computer-readable storage mediums to support receiving, from a computerized system, a first encrypted file entity key and signed access metadata, wherein the first encrypted file entity key is created by encrypting a file entity key using a first encryption key, the signed access metadata is signed by the file entity key and the encrypted file entity is created by encrypting a file entity using the file entity key. The approach then determines whether to facilitate the decryption of the encrypted file entity by the computerized system and sends a second encrypted file entity key to the computerized system if it is determined to facilitate the decryption. The approach prevents the computerized system to decrypt the encrypted file entity if it is determined not to facilitate the decryption of the encrypted file entity by the computerized system.

    Abstract translation: 提出了一种考虑系统，方法和计算机可读存储介质以支持从计算机系统接收第一加密文件实体密钥和签名的访问元数据的方法，其中通过加密文件实体来创建第一加密文件实体密钥 密钥使用第一加密密钥，签名的访问元数据由文件实体密钥签名，并且通过使用文件实体密钥加密文件实体来创建加密的文件实体。 该方法然后确定是否便利计算机化系统对加密文件实体进行解密，并且如果确定促进解密，则将第二加密文件实体密钥发送到计算机化系统。 如果确定不方便计算机化系统对加密文件实体的解密，则该方法防止计算机化系统解密加密文件实体。
