  Currently, special attention is being paid to scenarios where the
interconnection of devices with heterogeneous computational and communication
capabilities it is required. It is essential to integrate security services
during the stages of design and deployment of these networks since many of
these scenarios provide critical services such as medical health, payment
systems, military affairs, access control, e-banking, etc. This work analyses
several cryptographic primitives related to entity authentication providing
robust solutions according to device capabilities.
