Abstract:
Devices and methods use close range communication links, such as near field communication (NFC) protocol links, to enable users to authenticate mobile devices to one another to create or expand secure multicast groups. Once the two or more devices establish a close range communication peer-to-peer link the devices exchange multicast group communication data sufficient to permit the devices to receive or send multicast messages. Long range wireless or wired network communication links are then used for multicast message communications. Proximity limits of the close range communication P2P link enables mutual trust to be presumed among devices, reducing the need for security and authentication signaling. The limited range of close range communication P2Plinks renders multicast groups established in this manner less vulnerable to eavesdropping and intrusion. Embodiments enable users to initiate secure multicast group participation merely by bringing two or more devices into close proximity.
Abstract:
Providing for management of a dynamic mobile coupon (DMC) at a mobile device is described herein. Particularly, dynamic characteristics associated with the DMC, such as a redeemable value, can be utilized to browse, sort, search, recall, or redeem the DMC utilizing a user interface of the mobile device. 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, selling the DMC, and so on. Accordingly, provided is an efficient and personable way to manage mobile coupons in a mobile operating environment and provide increased value and utility for a user of such coupons.
Abstract:
Ancillary service capability data is received in real time from participating electrical vehicles (EVs) connected through EV charging equipment to a power grid. Aggregate offers based on the ancillary service capability data from participating EVs are generated and matched with requests received from electrical power generating entities for ancillary service electrical power. Associated with the matches ancillary power is transferred from batteries of one or more EV batteries to the power grid and based on received transaction parameters transaction payment is made.
Abstract:
Un procedimiento para comunicaciones inalámbricas por un nodo inalámbrico en una red inalámbrica entre iguales, P2P, que comprende: generar un valor de la métrica de conectividad, CM, indicativo de un número de otros nodos inalámbricos de la red inalámbrica P2P a la que el nodo inalámbrico está conectado; transmitir (402) el valor de CM; y que se caracteriza por: transmitir la información de conectividad completa mantenida por el nodo inalámbrico a una frecuencia determinada sobre la base del valor de CM.
Abstract:
Un sistema de Administracion (MS) administra privilegios de firmas para entidades que deseen firmas criptograficas, y una Autoridad Certificada (CA) proporciona un servicio de firmas criptograficas. El MS registra las entidades para el servicio de firmas criptograficas, determina los privilegios de las firmas para cada entidad, y procesa peticiones de firmas de entidades. Para el registro, el MS obtiene informacion de registro para la entidad e invoca a la CA para generar un certificado de identidad para la entidad. Este certificado de identidad contiene informacion criptografica usada para identificar de manera unica la entidad. Para la generacion de firmas, el MS recibe una peticion de firma de la entidad, autentifica la entidad, autoriza o niega la peticion sobre la base de los privilegios de firmas almacenados para la entidad, e invoca a la CA para generar la firma si la firma es autorizada. La CA proporciona el servicio de firmas criptograficas y genera firmas y certificados de acuerdo a lo dictado por el MS.
