| 20100202455 | METHOD FOR SECURE NETWORK BASED ROUTE OPTIMIZATION IN MOBILE NETWORKS - The present invention provides a method of route optimization involving a first mobile device associated with a first home gateway. One embodiment of the method is implemented in a first mobility forwarding entity and includes registering the first mobile device at the first mobility forwarding entity. The first mobile device is registered using a session key included in a registration message transmitted by the first mobile device. The embodiment also includes establishing a secure route between the first mobility forwarding entity and a terminating node using the session key. The secure route bypasses the first home gateway. | 08-12-2010 |
| 20110051912 | Secure Key Management in Conferencing System - Principles of the invention provide one or more secure key management protocols for use in a communication environment such as a conferencing system. For example, a method for managing a conference between two or more parties in a communication system comprises the following steps. An identity based authenticated key exchange operation is performed between a conference management element of the communication system and each of the two or more parties seeking to participate in the conference, wherein messages exchanged between the conference management element and the two or more parties are encrypted based on respective identities of recipients of the messages, and further wherein the conference management element receives from each party during the key authentication operation a random key component that is computed based on a random number selected by the party. The conference management element sends to each party a set comprising the random key components computed by the parties. The conference management element receives from each party a random group key component, wherein the random group key component is computed by each party via a computation based on the random number used by the party during the key authentication operation and the random key components computed by a subset of others of the two or more parties seeking to participate in the conference. The conference management element sends to each party a set comprising the random group key components computed by the parties such that each party can compute the same group key for use in communicating with each other party through the conference management element. | 03-03-2011 |
| 20110055567 | Secure Key Management in Multimedia Communication System - Principles of the invention provide one or more secure key management protocols for use in communication environments such as a media plane of a multimedia communication system. For example, a method for performing an authenticated key agreement protocol, in accordance with a multimedia communication system, between a first party and a second party comprises, at the first party, the following steps. Note that encryption/decryption is performed in accordance with an identity based encryption operation. At least one private key for the first party is obtained from a key service. A first message comprising an encrypted first random key component is sent from the first party to the second party, the first random key component having been computed at the first party, and the first message having been encrypted using a public key of the second party. A second message comprising an encrypted random key component pair is received at the first party from the second party, the random key component pair having been formed from the first random key component and a second random key component computed at the second party, and the second message having been encrypted at the second party using a public key of the first party. The second message is decrypted by the first party using the private key obtained by the first party from the key service to obtain the second random key component. A third message comprising the second random key component is sent from the first party to the second party, the third message having been encrypted using the public key of the second party. The first party computes a secure key based on the second random key component, the secure key being used for conducting at least one call session with the second party via a media plane of the multimedia communication system. | 03-03-2011 |

| 20100235890 | Communication of Session-Specific Information to User Equipment from an Access Network - In conjunction with establishment of a session between an access network and user equipment of a communication system, session-specific information is transmitted from the access network to the user equipment. The session-specific information transmitted from the access network to the user equipment comprises information to be utilized in an authentication protocol carried out between the user equipment and an authentication server of the system. For example, the session-specific information transmitted from the access network to the user equipment may comprise an identifier of a gateway coupled between the access network and the authentication server. | 09-16-2010 |
| 20100303238 | Session Key Generation and Distribution with Multiple Security Associations per Protocol Instance - A single instance of a session key generation protocol is executed in a manner that generates a plurality of security associations between user equipment and a first network element of a communication system. In one aspect, a first one of the security associations is utilized to secure data sent between the user equipment and the first network element in an ongoing communication. In conjunction with a handoff of the ongoing communication from the first network element to a second network element of the communication system, another one of the security associations is selected, and the other selected security association is utilized to secure data sent between the user equipment and the second network element in the ongoing communication. The security associations may comprise respective sets of session keys derived from a single pairwise master key. | 12-02-2010 |
