Abstract: Embodiments describe techniques in connection with configuring a firewall and/or reducing network traffic. According to an embodiment is a method for configuring a firewall to reduce unwanted network traffic. The method includes executing a web-server and detecting a passive socket has been created. The method also includes establishing contact with a firewall and requesting the firewall to permit flows directed to the passive socket. According to some embodiments, the method can include closing the web-server and destroying the passive socket. The firewall can be contacted with the destroyed passive socket information and can be sent a request to deny flows directed to the destroyed passive socket. If the passive socket is closed, the method can automatically revoke the request to the firewall to permit flows directed to the passive socket.

Abstract: Efficient transmission of cryptographic information in secure real time protocol. A transmitting terminal may be used to encrypt data with a session key derived from a bit-stream. The bit-stream may be sent with header information to the receiving terminal. To conserve bandwidth, the information may be divided into portions, and each portion transmitted with an encrypted data packet. The receiving terminal may be used to recover the bit-stream from the information portions in the packet headers, and use the bit-stream to derive the session key. The session key may be used to decrypt the data.

Abstract: A communications system and method of bootstrapping mobile station authentication and establishing a secure encryption key are disclosed. In one embodiment of the communications network, a distinguished random challenge is reserved for generation of a secure encryption key, wherein the distinguished random challenge is not used for authentication of a mobile station. The distinguished random challenge is stored at a mobile station's mobile equipment and used to generate a secure encryption key, and a bootstrapping function in the network uses a normal random challenge to authenticate the mobile station and the distinguished random challenge to generate the secure encryption key.

Abstract: In a communication system in which two communication entities seek to have a private or confidential communication session, a trust relationship needs first be established. The trust relationship is based on the determination of a shared secret which in turn is generated from contextual information. The contextual information can be derived from the circumstances surrounding the communication session. For example, the contextual information can include topological information, time-based information, and transactional information. The shared secret may be self-generated or received from a third party. In either event, the shared secret may be used as key material for any cryptographic protocol used between the communication entities.

Abstract: A subscriber station (110, 112) may be configured with a processing system having first and second security protocols (210, f2). The processing system uses the first security protocol (210) to generate a pseudo-secret key from a challenge received from a service provider, and uses the second security protocol (f2) to generate a response to the challenge from the pseudo-secret key.
