The present invention provides a method for secure transmission of information, comprising the steps of generating a first message at a sender device , the first message comprising first message data and a second symmetric key, the second symmetric key corresponding to a second 10 message, encrypting the first message with a first symmetric key to obtain a first encrypted message at the sender device, transmitting the first encrypted message from the sender device to a receiver device and decrypting the first encrypted message with the first symmetric key at the receiver device to obtain the first message data and the second symmetric 15 key at the receiver device. Further, a system therefor is also provided.
