摘要
Methods and apparatus are provided for secure and reliable transmission of messages over a silent alarm channel. A plurality of messages are transmitted by obtaining the plurality of messages; and transmitting the plurality of messages on a forward-secure channel to a receiver, wherein the forward-secure channel comprises a buffer having a plurality of entries, wherein each of the entries stores one of the messages and wherein at least one of the plurality of messages is maintained in the forward-secure channel after a receiver reads the channel. Two levels of encryption are optionally performed on the forward-secure channel. The messages carried by the disclosed silent alarm channels can comprise, for example, (i) entries in a security log; (ii) one-time passwords derived by authentication tokens; or (iii) tampering notifications from one or more sensor devices.
