Claim 15:
16. A system comprising:
one or more hardware processors; and
at least one computer-readable storage medium having stored therein instructions which, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
receiving, by a relying node in a network environment, attestation information from an attester node in the network environment as part of a unidirectional push of information from the attester node according to a unidirectional link layer communication scheme that implements either 802.1× unidirectional discovery and authentication or one or more link layer unidirectional discovery protocols;
verifying a trustworthiness of the attester node by identifying a level of trust of the attester node from the attestation information, wherein the attestation information includes signed synchronization information previously received by the relying node and the attester node; and controlling network service access of the attester node through the relying node in the network environment based on the level of trust of the attester node identified from the attestation information.
