摘要： Methods for establishing secure point-to-point communications in a trunked radio system include receiving, at a trunking controller, a request from a source endpoint for a traffic channel for confidential communications between the source endpoint and a destination endpoint using a shared unique first symmetric key. The trunking controller provides keying material related to the symmetric key over the secured control channel to at least one of the source or destination endpoints and assigns a traffic channel. Moreover, in response to the request, the controller assigns a traffic channel. The keying material enables the unique first symmetric key to be securely established between the source and destination endpoints.

摘要： Techniques are provided for enabling application steering/blocking in a secure network which includes a network entity, and a first tunnel endpoint coupled to the network entity over an encrypted tunnel. The first tunnel endpoint associates at least a first Security Parameter Index (SPI) to a first application identifier to generate first mapping information (MI), communicates the first MI to the network entity, and transmits an encrypted message to the network entity over the encrypted tunnel. The encrypted message includes an encrypted packet and an unencrypted header including the first SPI. The network entity determines the first SPI from the unencrypted header, determines the first application identifier based on the first SPI and the first MI, and identifies a first application associated with the first application identifier. The network entity can still perform application steering/blocking even though traffic passing through the tunnel is encrypted.

摘要： A method as provided enables mutual authentication of nodes in a wireless communication network. The method includes processing at a first node a beacon message received from a second node, wherein the beacon message comprises a first nonce value (step 405). An association request message comprising a certificate of the first node, a first signed block of authentication data, and a second nonce value is then transmitted from the first node to the second node (step 410). The second node can then verify a signature of the certificate of the first node and verify a signature of the first signed block of authentication data. An association reply message received from the second node is then processed at the first node (step 415), whereby the first node verifies a signature of a certificate of the second node and verifies a signature of a second signed block of authentication data.

摘要： An intermediate device of a network includes network and transport layers, a dispatcher, a splitter and a connections database. The splitter intercepts a message packet in the network layer and modifies the network routing header and transport header of the message packet to form a modified message packet. The dispatcher receives modified message packets from the transport layer, recovers information from the message packets, passes the modified message packets back to the transport layer and adapts the transport layer to adapt communication dependent upon the information recovered from the message packets. The connections database stores the original source address, the original destination address, the original source port identifier and the original destination port identifier of an incoming message packet. A message packet is modified, with reference to the connections database, so that message packets from the first and second nodes are routed through the dispatcher.
