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: A method for authentication that comprises:- (a) Providing at least a PIN and a confidential public key to an authorising computer; (b) Establishing a communication link between the authorising computer and at least one receiver remote from the computer, the communication link is not constrained by being a secure link; (c) Receiving, at the receiver, at least one acoustic signal representative of at least one private key-generated signal, the receiver transforming the acoustic signal to a signature signal; (d) Receiving, at the receiver, the PIN, the PIN being received separately from the acoustic signal; (e) Encrypting the signature signal with the PIN to render an encrypted signature signal; and (f) Sending the encrypted signature signal to the authorising computer for verification of the signature using the PIN and confidential public key.

Abstract: Method and apparatus for controlling access to a secure network, system or application is disclosed. In one embodiment, an apparatus for requesting authentication includes a storage medium that stores a cryptographic key, a processor that generates an access code using the cryptographic key, a converter that converts the access code into sound waves, and an audio output unit that outputs the sound waves encoded with the access code for authentication. An apparatus for granting authentication includes a storage medium that stores a cryptographic key, an audio input unit that receives sound waves encoded with a access code, a converter that recovers the access code from the sound waves, and a processor that generates a second access code using the cryptographic key and grants authentication if the access code corresponds to the second access code.
