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: 040954 19 BOOTSTRAPPFNG AUTHENTICATION USING DISTFNGUISILED RANDOM CHALLENGES ABSTRACT A COMMUNICATIONS SYSTEM AND METHOD OF BOOTSTRAPPING MOBILE STATION AUTHEATICATION AND ESTABLISHING A SECURE ENCRYPTION KEY ARE DISCLOSED. IN ONE EMBODIMENT OF THE CARRIMUNICATIOAS NETWORK, A DISTINGUISHED RANDOM CHALLENGE IS RESERVED FOR GENERATION OF A SECURE ENCRYPTION KEY, WHEREIN THE DISTINGUISHED RANDOM CHALLCRIGE IS NOT USED FOR AUTHENTICATION OF A MOBILE STATION. THE DISTING:UI@HCD RANDOM CHALLENGE IS STORED AT A MOBILE STATION'S MOBILE EQUIPMENT AND USED TO GENERATE A SECURE ENCRYPTION KEY, AND A BOOTSTRAPPING FUNCTION IN THE NETWORK USES A NORMAL RANDOM CHALLENGE TO AUTHENTICATE THE MOBILE STATION AND THE DISTINGUISHED RANDOM CHALLENGE TO GENERATE THE SECLVE CRICRYPTIOO KEY. 0

Abstract: Apparatus and method are disclosed for digital authentication and verification. In one embodiment, authentication involves storing a cryptographic key and a look up table (LUT), generating an access code using the cryptographic key; generating multiple parallel BPSK symbols based upon the access code; converting the BPSK symbols into multiple tones encoded with the access code using the LUT; and outputting the multiple tones encoded with the access code for authentication. In another embodiment, verification involves receiving multiple tones encoded with an access code; generating multiple parallel BPSK symbols from the multiple tones; converting the BPSK symbols into an encoded interleaved bit stream of the access code; de-interleaving the encoded interleaved bit stream; and recovering the access code from the encoded de-interleaved bit stream.

Abstract: Embodiments describe a method and / or system (200) whereby a secret key in a cryptographic system may be replaced without revealing the secret key. One embodiment comprises creating a first private key (210) and corresponding first public key. A second private key associated with the first private key and a second public key corresponding to the second private key are also created (220). The second private key is output once (230) such that it can be re-created and the second public key is output when outputting the first public key (240). The first private key is used for authentication (260). The method further comprises re-creating the second private key; and using the second private key for authentication. Another embodiment comprises creating a private key and corresponding public key with associated system parameter (410); outputting the system parameter when outputting the public key (430); and using the private key for authentication (460). The method may further comprise creating a new private key using the previous key and the system parameter (470).

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.
