摘要： 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.

摘要： A constrained proxy key is used to secure communications between two devices via an intermediary device. A first proxy key is generated at a host device (key generator device) based on a shared secret key, one or more constraints on the first proxy key, and a key derivation function. At least the shared secret key and key derivation function are known to the host device an a client device (authentication device). The first proxy key is sent to a proxy device to use in authenticating communications with the client device. An authenticated message is generated by the proxy device using the first proxy key and sent to the client device. The client device locally generates a second proxy key using the key derivation function, one or more constraints, and the shared secret key for authenticating the proxy device. The proxy device is authenticated if the client device successfully accesses the authenticated message from the proxy device using the second proxy key.

摘要： A cryptographically secure pseudo-random number generator is configured to obtain one or more unpredictable sources of entropy that provide a seed. A current internal state of the number generator is modified as a function of the current internal state and the seed to accumulate entropy. The modified internal state may be obtained by using non-linear feedback shift register operations on the internal state and the seed. A pseudo-random number is then generated based on the modified internal state of the number generator. The one or more unpredictable sources of entropy may be combined into the seed. The internal state of the number generator may be continually modified with additional seeds obtained from the one or more unpredictable sources and the current internal state. Additionally, the internal state of the number generator may be modified on demand with a new seed received from a calling application.

摘要： A feature is provided that facilitates securely creating, and/or replacing cryptographic keys. A first key pair is created comprising first private key and first public key. A second (spare) key pair is created comprising second private key and second public key. The second key pair is associated with the first private key. The second key pair is divided into shares and distributed to at least two shareholders. When the first key pair is to be replace, the second key pair is recreated and authenticated with at least a portion of the distributed shares. A trust level is associated with the second key pair corresponding to a trust level of the first key pair. The first key pair may be invalidated upon authentication of the second key pair. Further configurations provide for the creation of additional spare key pairs.

摘要： An apparatus and method for authentication having a processor and at least one activator coupled to the processor is claimed. A signature generator is coupled to the processor and capable of generating a secure identifier. An emitter coupled to the signal generator capable of emitting the secure identifier. A receiver receives the emitted secure identifier and verifies that the secure identifier was appropriately transmitted. The public key corresponding to the key identifier transmitted is accessed to determine the validity of the secure identifier using the accessed key and that the time indicated in the received secure identifier is verified to be within acceptable time tolerances.

摘要： One example provides a broadcast device configured to display an advertisement for viewing by a user and a mobile client device configured to capture information relating to the advertisement from the broadcast device. The mobile client device determines whether the captured information is sufficient to allow the mobile client device to generate an electronic coupon. If it is, the mobile client device generates a coupon may be stored in the mobile client device and subsequently presented at a point-of-sale device as part of a transaction. If the captured information is insufficient, the mobile client device may request additional information from an advertiser server either directly or via the broadcast device.

摘要： To inhibit cross-site forgery attacks, different types/classes of cookies are used. A first cookie and a second cookie are generated by a web server and provided to a client browser during a web session. The first cookie defines a first set of use conditions for when the first cookie is to be used within the web session. The second cookie defines a second set of use conditions for when the second cookie is to be used within the web session. The client browser determines which (if any) of the first cookie or second cookie to send to the web server based on the use conditions defined within each cookie and the operation(s) sought by the client browser. The web server may grant different or the same privileges to operation(s) being sought by the client browser depending on whether the first or second cookie is sent by the client browser.

摘要： A hand-held token can be operated to generate an acoustic signal representing the digital signature generated by a private key of a public key/private key pair. Verifiers that might be located at, e.g., buildings, in vehicles, at bank ATMs, etc. receive the signal and retrieve the corresponding public key to selectively grant access authorization to components served by the verifiers. Methods and systems permit adding and removing a token from the access list of a verifier. Other methods and systems enable the token to be used with several verifiers that are nearby each other, such as might be the case with multiple vehicles owned by the same user and parked nearby each other, without more than one verifier being operated to grant access.
