Assignee: NILE GLOBAL, INC.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 16:
17. A method of communications, the method comprising:
from a wireless sensor deployed at a customer site, connecting to a wireless access point (AP) deployed at the customer site;
based on a client signature that is generated using a private key stored in a Trusted Platform Module (TPM) of the wireless sensor, performing mutual authentication between the wireless sensor and an authentication server connected to the wireless AP, wherein based on the client signature that is generated using the private key stored in the TPM of the wireless sensor, performing the mutual authentication between the wireless sensor and the authentication server connected to the wireless AP comprises exchanging a server message, a server certificate, a server signature, a client message, a client certificate, and the client signature between the wireless sensor and the authentication server using a Transport Layer Security (TLS) protocol where a TLS client is the wireless sensor;
deriving a Pairwise Transient Key (PTK) for communications between the wireless sensor and the wireless AP in response to a Pre-Master Key (PMK) generated as a result of the mutual authentication; and
at the wireless sensor deployed at the customer site, conducting wireless communications with the wireless AP using the PTK.
