Abstract: A method for secure transmission of a data stream between at least one sender and at least one recipient comprises packetizing the data stream into a plurality of data packets of data bits. Each data packet is split into at least two subpackets and the subpackets are encrypted with a one-time pad stored at the sender. The encrypted subpackets are transmitted to the receiver by transmitting one of the two encrypted subpackets over a first transmission path and transmitting another one of the two encrypted subpackets over a second transmission path wherein the first transmission path is different from the second transmission path. At the receiver, the encrypted subpackets are decrypted using an identical copy of the one-time pad stored at the receiver and the information of the data packet is restored from the at least two subpackets. Furthermore, a system for secure transmission is provided.
