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: Methods and apparatus are presented herein for encrypting and authentication data, such that some of data can be transmitted in the clear but still be authenticated by the sender. A set of cleartext positions and/or a set of ciphertext positions are used to specify which data blocks will be used to generate an input checksum value and an output checksum value. These checksums are then used to generate an authentication tag.

Abstract: A method for permitting encrypted communications between two stations which are operable with compatible encryption algorithms that accept encryption keys having work factors with respectively different values, comprising: determining a lowest one of the different work factor values: providing an initial encryption key with a given work factor value; comparing the given work factor value with the lowest one of the different work factor values; and wherein, if the given work factor value is greater than the lowest one of the different work factor values, the method further comprises: deriving from the initial encryption key a final encryption key having a work factor value not greater than the lowest one of the different work factor values; and using the final encryption key for the encrypted communications.

Abstract: Systems and methods of securing wireless communications between a network and a subscriber station include inserting a marker denoting an encryption type within a random value used for authentication, calculating a first session key and a first response value as a function of the random value, then calculating a second session key and a second response value as a function of the random value, first session key and first response value. The two levels of session keys and response values may be used by upgraded subscriber stations and network access points to prevent attackers from intercepting authentication triplets.

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: An apparatus for providing authentication of a mobile station in a wireless communication system. The present invention takes the number dialed by the mobile station user and computes the 24 bit number (AUTH-DATA) for authentication in accordance with a hashing function that has the following characteristics. The hashing function takes as its input at least the entire dialed digit string contained in the request for service and the number of digits. In a preferred embodiment, the ordering of the digits affects the result, as well as, the values of the digits. The preferred embodiment of the hashing function also accepts some or all of the mobile station identifier data. The function provides as output a number of suitable size for input to a second calculation of an authentication signature, such as the 24 bits required for AUTH-DATA. The output number is created in such a way that there is a minimum likelihood that other sets of dialed digits may create the same result.
