    摘要: 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.

    摘要: A method and apparatus for secure generation of a short-term key SK for viewing information content in a Multicast-broadcast-multimedia system are described. A short-term key is generated by a memory module residing in user equipment (UE) only when the source of the information used to generate the short-term key can be validated. A short-term key can be generated by a Broadcast Access Key (BAK) or a derivative of BAK and a changing value with a Message Authentication Code (MAC) appended to the changing value. A short-term key (SK) can also be generated by using a private key and a short-term key (SK) manager with a corresponding public key distributed to the memory module residing in the user equipment (UE), using a digital signature.

    摘要: In a communication system in which two communication entities seek to have a private or confidential communication session, a trust relationship needs first be established. The trust relationship is based on the determination of a shared secret which in turn is generated from contextual information. The contextual information can be derived from the circumstances surrounding the communication session. For example, the contextual information can include topological information, time-based information, and transactional information. The shared secret may be self-generated or received from a third party. In either event, the shared secret may be used as key material for any cryptographic protocol used between the communication entities.

    摘要: 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.

    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: 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.
