Ad-hoc networks are subject to malicious attacks given their wireless nature and high dynamicity. Various security issues have been raised so far, especially access control. Our work focuses on a light and distributed AAA infrastructure that supports authentication and authorization. We make use of a distributed protocol based on the threshold cryptography theory, and the ISO 9798-3 authentication protocol standard. Access to the network is also controlled by an ACCESS TOKEN generated by the AAA service and referring to some Cryptographically Generated Addresses
