A content syndication access control solution is provided. An illustrative content syndication access control system comprises: a syndication subscriber for acquiring a authorized content syndication feed; content syndication providing means for authorizing the syndication subscriber according to a public key and submitting content to a syndication server; and the syndication server for performing an authorization on content items according to the public key and a symmetric key and encrypting the authorized content items and the symmetric key, and generating the content syndication feed according to the encrypted content items and the symmetric key. By means of the system, the granularity of access control can become finer, and the consolidated content feed maintains all access control information, so existing access control remains valid.
