Authentication Systems

The notion of digital identity cannot be fully understood without considering the concept of authentication. The aim of digital identity is simply to formalize the individualization of access to computer networks, conditional by the existence of means of verifying the digital identity of users or objects. We therefore need to be able to authenticate equipment, services and individual users, whether for local or broader networks, wired or wireless systems and client-server or distributed architectures. All aspects relating to private access, i.e. access control to information and resources reserved to certain entities, are dependent on authentication.
