Assignee: QUALCOMM INCORPORATED
Field: Digital communication (Electrical engineering)
Classification: CPC H  G | IPC H

Claim 0:
1. A method for providing broadcast communications security performed by a processor of a device, comprising:
generating a beacon type message;
cryptographically signing the beacon type message at least in part using a certificate to generate a signed beacon message, wherein cryptographically signing the beacon type message at least in part using the certificate to generate the signed beacon type message comprises:
generating a message payload;
generating a digital signature using at least in part the certificate and a private key of the device, the private key corresponding to a public key of the device associated with the certificate, wherein generating the digital signature using at least in part the certificate and the private key comprises:
generating a hash of the certificate;
combining the device message, a determined signing timestamp, and the hash of the certificate to form an authenticated payload; and
generating the digital signature using at least in part the authenticated payload, the certificate, and the private key;

generating a certificate identifying hash of the certificate; and
embedding the message payload, the digital signature, and the certificate identifying hash in the beacon type message to generate the signed beacon type message; and

sending the signed beacon type message in one or more broadcast transmissions from the device.
