Abstract
One aspect involves receiving by a tag of wireless communications that utilize a first security provision, and wireless communications that utilize a second security provision different from the first security provision. A different aspect involves receiving by an entity of an authentication request that is based on a first digital certificate unknown to the entity, and determining by the entity, without external authentication of the first digital certificate, whether the first digital certificate is in a trust relationship with a second digital certificate that is different from the first digital certificate and that is known to the entity.
