20100208898 | MANAGING GROUP KEYS - In an example, one or more cryptographic keys may be associated with a group. Any member of the group may use the key to encrypt and decrypt information, thereby allowing members of the group to share encrypted information. Domain controllers (DCs) maintain copies of the group's keys. The DCs may synchronize with each other, so that each DC may have a copy of the group's keys. Keys may have expiration dates, and any client connected to a DC may generate a new key when a key is nearing expiration. The various clients may create new keys at differing amounts of time before expiration on various DCs. DCs that store keys early thus may have time to propagate the newly-created keys through synchronization before other DCs are requested to store keys created by other clients. In this way, the creation of an excessive number of new keys may be avoided. | 08-19-2010 |
20110252229 | SECURING PASSWORDS AGAINST DICTIONARY ATTACKS - Described herein are various technologies pertaining to constructions of a password-based authentication protocol that are configured to allow a user to register with and authenticate to an online service without the online service receiving a password or a deterministic function of the password of the user. When registering with an online service, a client computing device establishes a cryptographically strong random secret and stores an encryption of such secret with a data storage device. The storage device also never receives the password or a deterministic function of the password. When the user wishes to authenticate to the online service, the user employs her password to retrieve the encrypted secret from the storage device, decrypts such secret, and utilizes the decrypted secret to answer a cryptographically strong challenge provided to the user by the online service upon the online service receiving a username pertaining to such user. | 10-13-2011 |
20120106738 | LOCATION BROKERING FOR PROVIDING SECURITY, PRIVACY AND SERVICES - Location brokering technique embodiments are presented that employ sensor data captured by a user's mobile device to determine the device's location, encrypt the location data and store it in a database. The location data is encrypted in such a way that it is possible to determine when a user's mobile device is currently in the same vicinity as another user's mobile device who is a member of the same group as the first user. However, the actual location and relative mobility or immobility of the users cannot be ascertained except by the users themselves via a decryption procedure or by trusted components. Services are provided can read the stored encrypted location data, processes it to determine if group members are in the same vicinity, and either respond to user queries about the location of other members of a group the user belongs to, or push this information to appropriate users. | 05-03-2012 |

20090279832 | Hermaphroditic Fibre Optical Connector System - The connector system provides two identical hermaphroditic housings, which accomplish a reliable connection of standard optical fiber connectors without the use of an adaptor. The connector system includes a first housing mounted to a first printed wiring board and a second housing mounted to a second printed wiring board. Each housing supports an optical fiber connector therein. Each housing includes an inner member and an outer member Springs are provided between the inner and outer members to provide biasing of the housings in the mating direction of the optical connectors. | 11-12-2009 |
20130209041 | Multi-Ferrule Optical Fiber Cable Assembly - An optical fiber cable assembly includes an optical fiber cable, an optical fiber connector, and a strain relief member. The optical fiber connector has a housing with at least two ferrules supporting a plurality of optical fibers of the cable. Each ferrule has at least two ribbons of optical fibers therein. The strain relief member has a flexible corrugated conduit. A method is also disclosed. | 08-15-2013 |
20130209042 | Optical Fiber Cable Assembly With Improved Strain Relief - An optical fiber cable assembly includes an optical fiber cable, an optical fiber connector and a strain relief member. The optical fiber connector has a housing supporting a plurality of optical fibers of the cable. The strain relief member has a flexible conduit, a first section and a second section spaced from the first section. The first section is connected to a rear end of the optical fiber connector and the second section is connected to a portion of the optical fiber cable. | 08-15-2013 |
20150023646 | FIBER OPTIC CONNECTOR REMOVAL CLIPS - A removal clip is provided for disconnecting a fiber optic connector from an array of installed fiber optic connectors. The removal clip includes an engagement portion for engaging the connector and a force transmitting structure that allows digital removal force from a user to be applied at a distance from the connector. The engagement portion may be generally U-shaped and includes opposing latch arms configured to accommodate the body of a fiber optic connector. The latch arms permit the engagement portion to snap attach to the connector. The force transmitting structure may include a beam and a handle extending axially or radially from the gripping section. Also included is an assembly of a removal clip attached to a fiber optic connector. | 01-22-2015 |
