Abstract:

Method and management server for revoking group server identifiers of compromised group servers. One method includes determining, with a management server, an identity-based cryptographic signing key based on a group server identifier. The method also includes distributing, via the management server, the identity-based cryptographic signing key to a group server. The method further includes receiving, at the management server, a security status indicating that the security of the group server is compromised. The method also includes, responsive to receiving the security status, distributing, via the management server, a revocation of the group server identifier to a plurality of communication devices.

International Classification:

H04W 40/24

Abstract:

Disclosed herein are methods and systems for maintaining routing tables in an ad-hoc wireless network. In an embodiment, a first node receives, from a second node having a second network address, a first data packet having a third network address as the source address and a fourth network address as the destination address. The first node determines that its server routing table (i) contains a stored server route to the fourth network address and (ii) does not contain a server route to the third network address, and responsively adds, to its server-to-client routing table, a server-to-client route to the third network address with the second network address as the associated next hop. The first node transmits, to the second node at the second network address, a second data packet that has the third network address as the destination address.

US Classification:

4554041, 4555501

Abstract:

A method and apparatus are provided, for accessing a data-capture device in a different domain, by public safety wireless communications equipment, for the purpose of obtaining information at an incident. A dispatch controller of a public safety wireless communications system receives an access token from a server of a non-public-safety network, when an incident occurs. The token allows access to a data-capture device, and is associated with the incident. The dispatch controller sends the token to the data-capture device, receives a data stream, and forwards the data stream to a public safety wireless communication device. The public safety wireless communication device may itself discover and access the data-capture device, and may receive the data stream directly from the data-capture device. The public safety wireless communication device may forward the data stream and/or the access token to other public safety wireless communication devices.

International Classification:

H04L 29/06

US Classification:

726 7

Abstract:

An apparatus for, and method of, single sign-on collaboration among a plurality of mobile devices, includes a server for issuing a first identity token to subsequently authenticate a user of a first of the mobile devices to a service provider, and for generating and sending a collaboration key to the first device based on the first identity token or user authentication. The first device generates and sends a collaboration credential based on the collaboration key to a second device paired with the first device. The server also issues a second identity token to subsequently authenticate to the service provider the user of the second device based on the collaboration credential received from the first device, to support single sign-on collaboration for the user across the plurality of mobile devices.

International Classification:

G06F 21/40

US Classification:

726 9

Abstract:

Multi-factor authentication is enabled across a plurality of communication devices. A user performs authentication by using a first authentication factor on a first of the communication devices, and by using a second authentication factor on a second of the communication devices. A collaboration credential is shared among the devices to enable the devices to collaborate with each other. Both of the authentication factors are bound together. A multi-factor identification token is issued to each device, to support multi-factor authentication for the user across the devices.
