Abstract
Various embodiments enable broadcast communications security. Various embodiments enable the authentication of broadcast communications. Various embodiments may enable asymmetric authentication and integrity protection of small size messages, such as one or more signed messages totaling a length of 250 bytes or less. Various embodiments may support cryptographic signing of beacon type messages using certificates. Various embodiments may include generating a beacon type message, cryptographically signing the beacon type message at least in part using a certificate to generate a signed beacon message, and sending the signed beacon type message in one or more broadcast transmissions in conjunction with, or independently of, certificate information used to verify the signed beacon message.
