    Abstract: PROBLEM TO BE SOLVED: To provide multisigning-protocol for robust multiple party digital signatures.
    SOLUTION: Embodiments describe a system and/or method for multiple party digital signatures. According to a first aspect, the method includes: establishing a first validity range for a first key; establishing a first validity range for at least a second key; and determining if the validity range of the first key overlaps the first validity range of at least the second key. A certificate is signed with the first validity range of the first key and the first validity range of at least the second key if the validity ranges overlap. According to another embodiment, signage of the certificate is refused if the first validity range of the first key does not overlap with the first validity range of at least the second key.

    Abstract: Techniques for associating software with hardware using cryptography are described. The software is identified by a software identifier (ID), and the hardware is identified by a hardware ID. The software is hashed to obtain a code digest. A code signature is generated for the code digest, software ID, and hardware ID. A code image is formed with the software, software ID, code signature, and a certificate. The certificate contains cryptographic information used to authenticate the certificate and validate the code signature. The code image is loaded onto a device. The device validates the software to hardware association prior to executing the software. For the validation, the device authenticates the certificate with a certificate authority public key embedded within the device. The device also validates t he code signature using the cryptographic information contained in the certificate, information in the code image, and the hardware ID embedded within the device.

    Abstract: This disclosure is directed to techniques for selection of wireless network interfaces for data communication within an access terminal. The techniques may rely on a set of interface selection rules to identify network interfaces that are eligible to serve a particular communication application or the type of traffic forwarded on behalf of another device. In addition, each network interface may be assigned a priority. Upon identifying eligible interfaces, e.g., interfaces that satisfy all of the interface selection rules, the techniques may involve selection of the eligible interface having the highest priority. The assigned priority may be dynamically adjusted based on the connection state of the interfaces, prioritization according to changes in system latency, interface cost, and the like.

    Abstract: Dynamic mobile coupons (DMCs) having a variable commercial value and/or other variable coupon characteristic are provided herein. By way of example, a DMC can be distributed to a mobile device based on criteria established by a sponsor of the DMC. A redemption value of the DMC can be variable and dynamically established based at least in part on data associated with a recipient mobile device. Upon redemption of the DMC at a retail entity, the value is fixed and applied to a transaction. Details of the transaction are provided to a remote clearinghouse that performs mediation and indemnification functions to finalize the transaction. As described, the subject disclosure provides a DMC that facilitates a rich and flexible mechanism to generate purchasing incentive for consumers in a mobile environment.

    Abstract: Providing for management of a dynamic mobile coupon (DMC) at a mobile dev ice is described herein. Particularly, dynamic characteristics associated wi th the DMC, such as a redeemable value, can be utilized to browse, sort, sea rch, recall, or redeem the DMC utilizing a user interface of the mobile devi ce. In other aspects, a DMC management application can interact with server components to backup and store DMC data, synchronize dynamic information (e. g., a dynamic redeemable value), access or manage a user profile, interface with other mobile devices to accomplish sharing, trading, exchanging, sellin g the DMC, and so on. Accordingly, provided is an efficient and personable w ay to manage mobile coupons in a mobile operating environment and provide in creased value and utility for a user of such coupons.
