Claim Text:
1. A method for transmitting a message from a sender to a receiver indicating a potential attack on a protected resource, comprising: obtaining said message, wherein a content of said message is not previously known to said receiver; encrypting, using at least one hardware device, said message using an authenticated encryption scheme, wherein said authenticated encryption scheme employs a secret key shared by said sender and said receiver, wherein said authenticated encryption scheme comprises an integrity check of said message; combining, using at least one hardware device, said message encrypted using said authenticated encryption scheme with a tokencode generated by a security token to generate a one-time passcode, wherein said one-time passcode is based on a forward secure pseudo random number derived from said secret key such that said secret key remains secure in a forward time direction; and transmitting said one-time passcode to a receiver.
