All revenues pledged to the payment of bonds shall be subject to a lien in favor of the holders of such bonds, and all such revenues received by the authority shall be immediately subject to such lien without any physical delivery thereof or further act by the authority. The lien shall be effective as against all parties asserting claims against the authority, whether by way of tort, contract or otherwise, whether or not such parties may have had notice of such lien. The pledge or trust agreement creating the same need not be filed or recorded except in the official minutes of the authority.
