摘要:
A method and apparatus for over-the-air provisioning of authentication credentials at an access device via a first access system, wherein the authentication credentials are for a second access system lacking an over-the-air provisioning procedure. For example, the second access system may be a 3GPP system using AKA authentication methods. The first access system may be CDMA, using an OTASP or IOTA procedure. Provisioning the authentication credentials may include provisioning any of a 3GPP AKA authentication root key (K), AKA authentication related parameters, an AKA authentication algorithm to be used in the 3GPP authentication, or authentication algorithm customization parameters.

A mutual authentication method is provided for securely agreeing application-security keys with mobile terminals supporting legacy Subscriber Identity Modules (e.g., GSM SIM and CDMA2000 R-UIM, which do not support 3G AKA mechanisms). A challenge-response key exchange is implemented between a bootstrapping server function (BSF) and mobile terminal (MT). The BSF generates an authentication challenge and sends it to the MT under a server-authenticated public key mechanism. The MT receives the challenge and determines whether it originates from the BSF based on a bootstrapping server certificate. The MT formulates a response to the authentication challenge based on keys derived from the authentication challenge and a pre-shared secret key. The BSF receives the authentication response and verifies whether it originates from the MT. Once verified, the BSF and MT independently calculate an application security key that the BSF sends to a requesting network application function to establish secure communications with the MT.

Mobile commerce authentication and authorization systems enable currently existing point-of-sale devices that are neither structurally nor systemically altered to conduct financial transactions with a customer using an access terminal across a wireless communications system. The point-of-sale devices receive an input from a payment instrument replacement, which identifies the transaction to the point-of-sale device as a transaction including an access terminal. Authentication of the user of the access terminal is achieved at least by application of position and/or location determinable features of the access terminal, the position and/or location of a point-of-sale device of a vendor or merchant where the customer seeks to purchase goods or services, and the payment sum entered on the point-of-sale device. A payment matching server may assist in processing the location data and the payment sum amount across communications network.

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.

The mobile commerce authentication and authorization system allows a user of a currently existing mobile wireless communications instrument to conduct financial transactions, including purchases, across a wireless communications system using location data to authorize and authenticate the user and the transaction. The location of the mobile wireless communications instrument and the location of a vendor point-of-sale device are matched with a payment sum. Authentication of the mobile wireless communications instrument user is achieved at least by application of the position and/or location determinable features of the mobile wireless communications instrument, the position and/or location of a point-of-sale device of a vendor or merchant where the instrument user seeks to purchase goods or services, and the payment sum entered on the point-of-sale device. A transaction matching subsystem located in a wireless customer server hub may assist in processing the location data and the payment sum across the wireless communications network.

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.

A secure seeding and reseeding scheme is provided for pseudorandom number generators by using a pre-stored initialization seed. This scheme initializes a pseudorandom number generator into an unknown state even when entropy collection is unavailable. A primary seed file and a shadow seed file are maintained with initialization seed information in a secure file system. If the primary seed file is corrupted, the pseudorandom number generator is seeded with the content of the shadow seed file. Additionally, a trusted timer or clock may be mixed with the pre-stored initialization seed to add entropy even when the pre-stored seed information has been compromised.

Disclosed is a method for virtual pairing of a first peer device with a second peer device. In the method, a nonce is generated at the first peer device for use in virtually pairing the first and second peer devices to establish a first-type wireless connection. The nonce is forwarded from the first peer device to the second peer device over an already established second-type wireless connection between the first and second peer devices. At least one new key is generated from the nonce and a shared key for the already established second-type wireless connection. The first peer device is virtually paired with the second peer device using the at least one new key to establish the first-type wireless connection between the first and second peer devices.

Device authentication is based on the ability of a human to synchronize the movements of his or her fingers. A pairing procedure for two wireless devices may thus involve a synchronization test that is based on the relative timing of actuations of input devices on each of the wireless devices. In some aspects a synchronization test involves determining whether actuations of user input devices on two different wireless devices occurred within a defined time interval. In some aspects a synchronization test involves comparing time intervals defined by multiple actuations of user input devices on two wireless devices.
