The invention relates to a method for accessing a data memory (128) of a cloud computer system (102) by means of a gateway computer system (100), wherein the gateway computer system is connected to the cloud computer system by means of a network (106), wherein the gateway computer system stores authentication data (118) of a user (114) for authentication with respect to the cloud computer system and at least one cryptographic key (120), comprising the following steps: establishing a secured connection (110) between a first terminal (112) of the user and the gateway computer system, transferring a file (101) from the terminal to the gateway computer system via the secured connection, - establishing a session (154) between the gateway computer system and the cloud computer system by means of the network, authenticating the user with respect to the cloud computer system by means of the gateway computer system by using the session, in that the gateway computer system accesses the authentication data of the user stored in the gateway computer system for the authentication of the user, encrypting the file by means of the gateway computer system by using the cryptographic key, transferring the encrypted file (132) from the gateway computer system to the cloud computer system by means of the session, storing the encrypted file in the data memory of the cloud computer system. |
