Abstract
A process includes communicating by a first device, with a second device. The communicating includes the first device receiving data from the second device that represents a certificate. The certificate binds a hierarchy of logical identifiers to a cryptographic key. The hierarchy of identifiers includes a first logical identifier that corresponds to a group membership. The process includes authenticating, by the first device, the second device based on the certificate. The process includes allowing, by the first device, a secure connection to be set up between the first device and the second device based on whether the first logical identifier represents that the second device is a member of a first group of devices of which the first device is a member.
