A key tree is produced so as to include a plurality of subtrees that are ... 05/03/07 - 20070098176 - Wireless lan security system and method A wireless LAN security system and method. The system includes a separate server managing an encryption key and an authentication certificate used for security, and providing the encryption key and the authentication certificate to an apparatus that requests them. Such apparatus including a wireless LAN terminal requesting the encryption key ... 04/19/07 - 20070086591 - Method and apparatus for establishing a security association A method for establishing a security association between a client and a service node for the purpose of pushing information from the service node to the client, where the client and a key server share a base secret. The method comprises sending a request for generation and provision of a ... 04/05/07 - 20070076889 - Pre-generation of generic session keys for use in communicating within communications environments Generic session keys are pre-generated and stored in a pool of session keys for later use in communicating within a communications environment. The session keys that are stored in the pool are pre-encrypted with the private key of the entity storing those keys. To communicate between entities, a pre-encrypted session ... 12/21/06 - 20060285694 - Method and system for managing key of home device in broadcast encryption (be) system A method and a system for managing a key of a home device in a broadcast encryption system are provided. A hierarchical structure of a group set comprising a plurality of nodes corresponding to the home server and a plurality of nodes corresponding to the home device is formed. A ... 09/21/06 - 20060210085 - Method and apparatus for expiring encrypted data One embodiment of the present invention provides a system that can expire encrypted-data. During operation, the system receives an expiry-request that includes object-identifying information, which can be used to identify a set of database objects that contain the encrypted-data, wherein a database object can be a table, a partition, a ... 08/31/06 - 20060193474 - Content distribution using set of session keys A method includes generating a set of session keys and encrypting content utilizing the set of session keys to generate encrypted content. The set of session keys is transmitted. The encrypted content is transmitted to a content destination, so as to enable the content destination, utilizing the set of session ... 07/13/06 - 20060153388 - Integrated and monolithic package structure of acoustic wave device An integrated and monolithic package structure of acoustic wave device is provided that includes a first device, a conjunction layer, a second device and a conductive layer. The first device is placed in a way of face up, the second device is placed in a way of face down, and ... 10/13/05 - 20050226424 - Key allocating method and key allocation system for encrypted communication Both a management server and a validation server are installed. Both a terminal and a terminal register setting information which is usable in an encrypted communication in the management server. When carrying out the encrypted communication, the management server searches the registered setting information for coincident setting information. The management ... 07/21/05 - 20050157880 - Computer system having an autonomous process for centralized cryptographic key administration In scalable multi-process and possibly multi-node application environments, the management of sensitive data, such as cryptographic keys, is complicated by the number of processes, the frequency at which they are created and destroyed, and by the desire to avoid storing any keys in the clear in these processes or in ... 06/30/05 - 20050141720 - Encrypted communication system, key delivery server thereof, terminal device and key sharing method Provided is a method for updating a group key in a highly secure manner and at high speed. A method includes: a step of making subscriber terminals (20) perform a part of decryption of an encrypted group key used to decrypt the information before distribution of the group key; a ... ### FreshPatents.com Support |
