Abstract: Method and apparatus for secure transmissions. Each user is provided a registration key. A long-time updated broadcast key is encrypted using the registration key and provided periodically to a user. A short-time updated key is encrypted using the broadcast key and provided periodically to a user. Broadcasts are then encrypted using the short-time key, wherein the user decrypts the broadcast message using the short-time key.

Abstract: A method of authenticating anonymous users while reducing potential for "middleman" fraud includes the step of constructing a puzzle in response to information received from a software user. The puzzle includes the received information. The puzzle is sent to the user by a software provider. The user solves the puzzle and returns the solution to the provider. The puzzle includes a portion of a value derived from an encrypted "cookie" and an exponentiation of the derived value. The cookie includes information about the user.

Abstract: A method for constructing keyed integer permutations over the set Z N . where N can be factored into p and q, or N can be prime. N bits are permuted by deriving a keyed permutation of representative indices. When N is factorable into p and q, the set of indices are divided into two portions. The portions undergo iterative processing called "rounds," and in each round, a first half-round function operates on the first portion to form a first half-round value; the first half-round value and the second portion are added together by a modulo-p adder to form a first output value; a second half-round function operates on the second portion to form a second half-round value; and the second half-round value and the first portion are added together by a modulo-q adder to form a second output value. In this manner, outputs of the rounds are reordered. If N is prime and not less than 13, then N is separated into composite values s and t, and two sets are formed with s and t elements, respectively. Each set is then permuted using the method for when N is not prime. At the end of each round, the two blocks are combined using a mixing operation.

Abstract: A system and method for digital tickets. An issuer provides a digital ticket to a portable wireless devices such as a sonic token, e.g., acoustic key fob or wireless telephone. The ticket can include a ticket index that may be encrypted. When entry is desired into an entity (such as a movie theater) whose access is controlled by a verifier, a user manipulates the token to wirelessly (e.g., acoustically) transmit the ticket index to the verifier, which grants access if the ticket is valid and has not previously been used or voided.

Abstract: Un procedimiento para transmisiones seguras en un canal de radiodifusión, comprendiendo el procedimiento: obtener (714) una clave a corto plazo (800) para un mensaje para su transmisión, correspondiendo la clave a corto plazo a un identificador de clave a corto plazo; determinar (702) una clave de acceso de radiodifusión para el mensaje, correspondiendo la clave de acceso de radiodifusión a un identificador de clave de acceso (804); cifrar (716) el mensaje con la clave a corto plazo; formar (718) una cabecera de protocolo de Internet que comprenda el identificador de clave a corto plazo; y transmitir (718) el mensaje cifrado en el canal de radiodifusión con la cabecera de protocolo de Internet, en el que la clave a corto plazo (714) se calcula en función del identificador de clave a corto plazo y de la clave de acceso de radiodifusión.
