TLDR
In this paper, a method for transmitting and receiving a secure message is proposed. But this method is restricted to the first secret values (400) being known only to the originating device and one or more intended recipient devices of the message.Abstract:
A method for transmitting and receiving a secure message. Transmission is by generating, using a device identifier (408), an application identifier (406) and an application value (412), of a message value (502), combining the message value (502) with one or more first secret values (400), said secret values (400) being known substantially only to the originating device and one or more intended recipient devices of the message, to establish a secret message value (506), applying the secret message value (506) and the message to an encoding process (602) to form a secure message block (604), and combining an address (616, 618) with a device identifier (408), the application identifier (406), the application value (412) and the secure message block (604), to form a secure message (606) for transmission which is decodable by the one or more of said intended recipient devices which thereby recover the message, the address, the device identifier, the application identifier and the application value.read more

Preliminary destination-dependent evaluation of message content
Edward K. Y. Jung,Royce A. Levien,Robert W. Lord,Mark A. Malamud,William Henry Mangione-Smith,John D. Rinaldo +5 more
TL;DR: In this article, a system, method, computer program product, and carrier are described for causing message content to undergo an evaluation mode at least partly dependent upon one or more message content destinations and indicating at least one outcome of the evaluation mode before detecting an apparent authorization to transmit the message content.

End-to-end encryption system and method of operation
TL;DR: In this article, an efficient end-to-end encryption system including key management procedures for providing secure, financial data communication between a system user at one of a plurality of transaction terminals of one of the plurality of acquirer institutions and one of an issuer institutions, with selected elements of the data being encrypted, decrypted and processed using a onetime session key which is similarly encrypted with master keys and efficiently sent along with the specific segments of the request and response messages.

Tokenless biometric transaction authorization system
TL;DR: A tokenless identification system and method for authorization of transactions and transmissions is described in this article, which is based on a correlative comparison of a unique biometrics sample, such as a finger print or voice recording, gathered directly from the person of an unknown user, with an authenticated biometric sample of the same type obtained and stored previously.

Digital signature with auditing bits
Bruce Schneier,John Kelsey +1 more
TL;DR: In this paper, the authors proposed a method for digitally signing a message by a tamper-resistant device to generate a digital signature. The method includes the step of hashing the message to form message bits; and encrypting with a private key the message bits, redundancy bits for the security of the signature, and auditing bits to form the digital signature for the message.
