The invention relates to a process for accessing a data storage device (128) of a cloud computer system (102) through a gateway computer system (100) which is connected with the cloud computer system over a network (106) and which stores at least one cryptographic key (120), the cloud computer system being associated with a URL and the gateway computer system being associated with an IP address, the Internet Domain Name System being modified to resolve the domain contained in the URL of the cloud computer system into the IP address of the gateway computer system, this process comprising the following steps:
Setting up a protected connection (110) over the Internet between a first piece of terminal equipment (112) of the user and the gateway computer system by inputting the URL of the cloud computer system into a program of the piece of terminal equipment, and using the modified Domain Name System for name resolution of the URL, so that the protected connection is set up with the gateway computer system instead of with the cloud computer system;Transferring a file (101) over the protected connection from the terminal equipment to the gateway computer system;Setting up a session (154) over the network between the gateway computer system and the cloud computer system;Encrypting the file by the gateway computer system using the cryptographic key;Transferring the encrypted file (132) through the session from the gateway computer system to the cloud computer system;Storing the encrypted file in the data storage device of the cloud computer system. |
