Process and system for data transmission

#Field of the Invention

#The present invention relates to a process and a system for data transmission.

#Description of the Related Art

#A more complete appreciation of the invention and many of the attendant advantages thereof will be readily obtained as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings, wherein:

#FIG. 1 shows a block diagram with the individual components for the encryption of data and for the transfer of the encrypted data.

#FIG. 2 shows a block diagram with the individual components for the authentication and decryption of the encrypted data.

#Referring now to the drawings, wherein like reference numerals designate identical or corresponding parts throughout the several views.

#In FIG. 1, the reference mark 10 refers to a central module. The central module 10 can, for example, be formed as a software module of a network server. The central module 10 can also, of course, be formed completely as a hardware module with appropriate electronic circuits. In FIG. 1, the reference mark D refers to electronic data. The data D can be electronic data of any kind, for example E-mail messages, texts, animations, audio files, video files, or electronic data of any other kind. In FIG. 1, the reference mark A refers to authentication data and the reference mark S refers to an electronic key. The authentication data A can, for example, include a user name and a password or pass phrase. The electronic key S can, for example, consist of a symmetrical electronic key with a secret key or an asymmetrical electronic key with a public key and a private key. The authentication data A are stored as assigned to the electronic key S while, for example, with the central module 10 including a corresponding table. In FIG. 1, the reference mark 40 refers to a communications network. The communications network can, for example, refer to the Internet and can be constructed from various networks of differing technologies. Thus, the communications network can include GSM networks, UMTS networks, WLAN networks, Ethernet networks, UWB networks, or networks of any other kind. As shown in FIG. 1, the central module 10 can in particular be connected to the communications network 40. Data D can be encrypted by means of the electronic key S and an encryption module of the central module 10. Such encryption can refer to any encryption algorithm, for example a DES algorithm (DES: data encryption standard), a PGP algorithm (PGP: pretty good privacy), an IDEA algorithm (IDEA: international data encryption standard), or any other encryption algorithm. Encrypted data vD are generated by the encryption of the data D. The authentication data A and the electronic key S can moreover be stored as assigned to an identification iD of the data, so that the authentication data A and the electronic key S are valid only with reference to data that can be identified by the identification iD of the data. Corresponding tables can of course also be provided for in the central module 10 with reference to the identification iD of the data.

#In FIG. 1, reference mark 20 refers to a communications terminal. The communications terminal 20 can be any terminal of a user, for example a mobile computer such as a notebook or a PDA (PDA: personal digital assistant), a mobile telephone, a games console, a permanently installed computer, or any other communications terminal. As shown in FIG. 1, the communications terminal 20 can be connected to the communications network 40. Such a connection can refer to a wireless connection, such as a WLAN connection, a GSM connection, or any other wireless connection, or to a wire-based connection, such as a twisted-pair Ethernet connection, or any other wire-based connection.
