Resumé:
In this thesis, we study the use of the identity in the authentication mechanisms and
improve the access control in different kinds of networks . The identity can be biometric
public features, simple strings (email addresses, login...), etc. The goal of our work is
to improve the security of the system using this identity without any compromise. We
have two main parts in the thesis depending on the deployed identity. The first part is
dedicated to systems using biometric features. We have studied the use of biometric and
developed new algorithms for Home Network and e-Passports authentication mechanisms.
The cryptographic parameters will be generated using the biometric templates and hence
personalized for the user. The second part is dedicated to systems using simple string like
email addresses as identifier to access to services. The study was done on IP Multimedia
Subsystem (IMS). Our contribution in this context consists in a new authentication
mechanism relying on Identity Based Cryptography (IBC) for the IMS architecture. The
goal was to authenticate the users using their public and private identifiers to overcome
known weakness in the Authentication and Key Agreement (AKA) protocol.
In both cases, the use of identity in the authentication was helpful to the system from
the perspectives of performance and security.
