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 updatedkey is encrypted using the broadcast key. The short-time key is available with each broadcast message,wherein sufficient information to calculate the short-time key is provided in an Internet protocol headerpreceding the broadcast content. Broadcasts are then encrypted using the short-time key, wherein the user decrypts the broadcast message using the short-time key.

Abstract: Un procedimiento que comprende: generar un secreto maestro compartido, en el que el secreto maestro compartido comprende una clave maestra por pares, PMK; generar un conjunto de datos de clave efímera compartida, en el que el conjunto de datos de clave efímera compartida se genera independiente del secreto maestro compartido, y en el que una duración de validez del conjunto de datos de clave efímera compartida es menor que una duración de validez del secreto maestro compartido; obtener una clave transitoria por pares, PTK, basada en el secreto maestro compartido; y cifrar al menos un mensaje que se va a transmitir a al menos una estación (118, 120) en base al menos al secreto maestro compartido, a la PTK y al conjunto de datos de clave efímera compartida.

Abstract: A puzzle-based protocol is provided that allows a token and verifier to agree on a secure symmetric key for authentication between the token and verifier. A token stores a secret key and one or more puzzle-generating algorithms. The verifier independently obtains a plurality of puzzles associated with the token, pseudorandomly selects at least one of the puzzles, and solves it to obtain a puzzle secret and a puzzle identifier. The verifier generates a verifier key based on the puzzle secret. The verifier sends the puzzle identifier and an encoded version of the verifier key to the token. The token regenerates the puzzle secret using its puzzle-generating algorithms and the puzzle identifier. The token sends an encoded response to the verifier indicating that it knows the verifier key. The token and verifier may use the verifier key as a symmetric key for subsequent authentications.

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 and apparatus for decrypting stream ciphers. An SSC2-type stream cipher is decrypted by utilizing the period of LFG output and the correlation of the LSBs of LSFR output. A dynamic probability of error for each bit of a data stream is calculated to determine whether a particular bit should be inverted.
