Zusammenfassung:A communication system (100) includes a first communication terminal (110) and a second communication terminal (120). The first communication terminal (110) generates a first shared key (SKA), and the second communication terminal (120) generates a second shared key (SKB). The first communication terminal (110) stores the second shared key (SKB) of the second communication terminal (120), and the second communication terminal (120) stores the first shared key (SKA) of the first communication terminal (110). The first communication terminal (110) sends a challenge string (CS1) to the second communication terminal (120), the second communication terminal (120) generates a response string (RS1) by performing reversible encryption operations to the challenge string (CS1) with the first shared key (SKA) and the second shared key (SKB), the second communication terminal (120) sends the response string (RS1) to the first communication terminal (110), and the first communication terminal (110) verifies the response string (RS1).
