发明名称 METHODS AND APPARATUS FOR SOURCE AUTHENTICATION OF MESSAGES THAT ARE SECURED WITH A GROUP KEY
摘要 Methods, systems and apparatus are provided for source authentication. In accordance with the disclosed embodiments, a key-management server generates (920) a key-delivery message that includes a key data transport payload secured with a group key, and a source authentication payload. Upon receiving the key-delivery message at a communication device, the communication device may verify (930) whether the source authentication payload of the key-delivery message is valid. When the source authentication payload is determined to be valid (940), the communication device thereby authenticates that the key-delivery message was transmitted by the key-management server.
