TRANSPORT LAYER SECURITY (TLS) BASED METHOD TO GENERATE AND USE A UNIQUE PERSISTENT NODE IDENTITY, AND CORRESPONDING CLIENT AND SERVER

摘要

A Transport Layer Security, abbreviated TLS, based method to generate and use a unique persistent node identity for identifying and authenticating a client (1) in a telecommunication network (2) comprises establishing a secure TLS connection between the client (1) and a server (3) and generating at the client (1) and the server (3) a shared secret key value K through a computational algorithm with a difficulty condition D obtained from a difficulty controller (7) and limiting the number of valid node identities.
