According to the method, a first communication device (1), such as an RFID reader, authenticates a second communication device (3), such as an RFID tag, by using an asymmetric authentication protocol based on a generated a session key. The tag authenticates the reader by using a symmetric communication protocol based on a generated other session key. At least a portion of the session key is used to generate the other session key."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Authentication by use of symmetric and asymmetric cryptography","description":"The present invention concerns a mutual authentication method in a communication system.
