摘要： A method for establishing a secret key between two nodes in a communication network, in particular in a wireless local area network (WLAN), includes concealment of the fact that a key exchange occurs, one of the nodes—first node (B)—broadcasts one or more packets (Pi) that can be received by the other node—second node (A)—, wherein the packets (Pi) contain each a first key (Ki) and wherein the packets (Pi) are each encrypted with a second key (ki) before being sent, the second node (A) randomly chooses one packet (Pm) from the packets (Pi) received and breaks the encryption of the chosen packet (Pm) in order to obtain the first key (Km), and the second node (A) initiates a key exchange protocol, wherein the second node (A) encrypts the message to be sent for initiating the key exchange protocol with the revealed key (Km).
