Abstract
To improve known encryption methods for communication in non-secured wireless networks, the invention proposes using an active key for encryption, in each instance, and sending along a new key in the messages, in each instance, which key, after it has been received completely, becomes the key used, and, once again, another new key is exchanged. This allows dynamic encryption, which allows an interception-proof connection, starting from a secure initial exchange of keys, for example.
Claims10
Method for the encryption of data within the scope of a data transmission between two nodes of a communication network, in which a message (6) to be sent between the two nodes is encrypted in the transmission node, using an active key (3), and transmitted to the reception node, and decrypted there using the active key (3),
- wherein the message, aside from a header (8) and a user data part (10), also has an encryption data part (9) in which data of a new key (4) are sent, and, after complete sending and reception of the new key (4), both nodes replace the active key (3) with the new key (4) for further communication.
