METHOD AND ASSEMBLY FOR ESTABLISHING A SECURE COMMUNICATION BETWEEN A FIRST NETWORK DEVICE (INITIATOR) AND A SECOND NETWORK DEVICE (RESPONDER)

摘要

The invention relates to a method for establishing a secure communication between a first network device (initiator) and a second network device (responder) in a communications network, and to an assembly of network devices that is suitable for this purpose, characterised in that, using a symmetric cryptosystem, in which both network devices each use the same secrets as a key for coding and decoding datasets, a respective separate authentication is carried out in relation to the first and the second network device, before generation of a secret to be used as a common key for secure communication.
