Secure Communications Between Multi-Capacity Devices with Authentication Support by Network Operators
In this paper, the authors propose to benefit from each natural network authentication procedure provided by operators to allow mutual authentication between two multi-capacity devices and guarantee the same security level to both of them. Operators can agree providing jointly this authentication service so multi-operator crossed authentication infrastructures can take place for instance over internet. As such, users needing strongly secure interconnectivity (e.g. SIP usage or over ad hoc infrastructures) can access to this service through Internet with no huge extra costs contrary to PKI or Kerberos solutions.
