Abstract:
PROBLEM TO BE SOLVED: To provide a method and a system for efficiently establishing secure communications between mobile devices in a wireless network. SOLUTION: The system utilizes public key cryptography and unique hardware identifiers that enables authorizations for accessing wireless networks, such as picocells. Furthermore, the system eliminates from a mobile user the need for maintaining a plurality of secrets, such as user identifier/password pairs, PINs, or encryption keys, for accessing each device. Wireless devices distributed throughout an enterprise becomes capable of being efficiently initialized for secure communications. Well-known public key cryptography and machine unique identifiers are utilized to establish a secure channel and initialize the wireless devices. The wireless devices are enabled, to be paired or permanently associated by a user or a network administrator. Well-known public key cryptography and machine unique identifiers are utilized to establish a secure channel and associate the devices with each other. COPYRIGHT: (C)2010,JPO&INPIT

PROBLEM TO BE SOLVED: To provide a method and a system for efficiently establishing secure communication between mobile devices in a radio network. SOLUTION: This method enables the permission of the access to a radio network such as pico-cell by using a public key encryption and an inherent hardware identifer. This method eliminates the need to hold a plurality secrets, such as a pair of user identifers/passwords, PIN, or an encryption key, to access the devices which may need access respectively for mobile user. Wireless devices distributed to a whole enterprise can be efficiently initialized for secure communication. COPYRIGHT: (C)2006,JPO&NCIPI

Abstract:
Un metodo y sistema para establecer eficientemente comunicaciones seguras entre dispositivos moviles en una red de radio. La presente invencion utiliza criptografia de clave publica e identificadores de equipo fisico unicos para permitir autorizacion para acceso a redes inalambricas tales como picoceldas. La presente invencion evita que el usuario movil mantenga una pluralidad de secretos tales como pares de clave/identificador de usuario, PINs o claves de cifrado, para acceso a cada dispositivo al cual pueda requerir accesar. Dispositivos inalambricos a traves de una empresa se activan para ser inicializados eficientemente para comunicaciones seguras. Identificadores unicos de maquina y criptografia de clave publica bien conocidos, se utilizan para establecer un canal seguro e inicializar los dispositivos inalambricos. Dispositivos inalambricos se activan para formar en pares o asociar permanentemente por un usuario o un administrador de red. Identificadores unicos de maquina y criptografia de clave publica bien conocidos, se utilizan para establecer un canal seguro y asociar los dispositivos entre si. Esto es extremadamente util para asociar audifonos inalambricos o microtelefono inalambrico con un telefono o asociar un raton inalambrico con una computadora.
Abstract:
Un método para inicializar comunicaciones seguras entre un primer dispositivo (1003) y un segundo dispositivo (1001), teniendo dichos primer y segundo dispositivos una clave pública de una Autoridad Certificadora (1005) y un certificado (1050) de dispositivo, teniendo cada uno de dichos certificados de dispositivo un identificador (1015) de hardware único asociado a dicho dispositivo respectivo, y una clave (1040) pública asociada a dicho dispositivo respectivo, comprendiendo dicho método las operaciones de: establecer (1010) una sesión entre dicho primer dispositivo y dicho segundo dispositivo; negociar la encriptación en una sesión bidireccional y los requerimientos de la autentificación mutua entre dicho primer y dicho segundo dispositivo; intercambiar certificados de dispositivo de dicho primer dispositivo y dicho segundo dispositivo; verificar criptográficamente el certificado recibido utilizando la clave pública de dicha Autoridad Certificadora; cada uno de dicho primer y dicho segundo dispositivos crea un desafío y lo envía al otro de entre dichos primer y segundo dispositivos, cada uno de dicho primer y dicho segundo dispositivos responde (1070) a dichos desafíos respectivos firmando dicho desafío recibido, utilizando la clave privada del dispositivo receptor, residiendo dichas claves privadas en una memoria protegida respectiva en cada uno de dichos dispositivos; cada uno de dicho primer dispositivo y dicho segundo dispositivo devuelve dicho desafío firmado; verificar criptográficamente que la firma del desafío firmado recibido corresponde al desafío enviado previamente por dicho dispositivo receptor; establecer un acuerdo de clave entre dicho primer y dicho segundo dispositivos; y, establecer comunicaciones seguras si tienen éxito todas las operaciones de verificación anteriores.

Abstract:
A multinode, multicast communications network has a distributed control for the creation, administration and operational mode selection operative in each of the nodes of the network. Each node is provided with a Set Manager for controlling either creation of, administration or access to a set of users to whom a multicast is to be directed. The Set Manager maintains a record of the local membership of all users associated with the node in which the Set Manager resides. A given Set Manager for each designated set of users is assigned the task of being the Set Leader to maintain membership information about the entire set of users in the multicast group. One of the Set Managers in the communications network is designated to be the Registrar which maintains a list of all the Set Leaders in the network. The Registrar insures that there is one and only one Set Leader for each set of users, answers inquiries about the membership of the sets and directs inquiries to appropriate Set Leaders if necessary. All of the set creation, administration and control functions can therefore be carried out by any node of the system and provision is made to assume the function at a new node when failure or partition in the network occurs.
